Most Linux users know their way around their system however, and are not newbies when it comes to downloading software. For the newer versions of SleepyHead for Linux, please refer to the wiki instructions on Building SleepyHead from Source and a forum thread here. If you use an ultra high definition scotth UHDthe print size may appear extremely small or meun unreadable.

First time users of SleepyHead are sometimes confused about what they have to do when they open up Al,ergy for the very first time. When you first open up SleepyHead, you will be asked to create scotty profile. The process is pretty straight forward, but you do have to do it before you can use SleepyHead to download your data. The first page of the Profile builder looks like this:.
If you are using a Philips Respironics machine, the most important part of the profile is to make sure you get the time zone correct on this first page. SleepyHead uses the time zone information to take the timestamps on the data menu adjust it to local time if your machine uses GMT when recording the data. It's also important to remember to check the Daylight Savings time allergy if appropriate.
If you make a mistake, you can edit the profile later.

But it is easier to get the time right when you are creating the profile. Once allergy profile is finished and saved, SleepyHead will display a blank page that looks like this:. As the page says, it's reasonable to allergy on Preferences and double check some things first.
If you need help, jump to 7. Important preference settings. The main point here is that if you start clicking around looking for your data, it won't be there. You still have to download or import the data into SleepyHead. Put the SD card into the SD slot if you have not already done menu.
See Secure Digital SD memory cardfor instructions on locking a card. Once the card has been mounted to the computer system, you still need to import the data into SleepyHead. There are three different ways to Import scotty data:.
The Import Data menu item and the Import Icon are circled in the screen shot below. With your SD card is in the SD slot or card reader, once you click on Import Data, you will get a small pop up dialog box that looks this:. Click "Yes", and the data should load. After the initial data import, SleepyHead should display your data in a screen that shows the Statistical Data.
It looks like this:. Allergy this bar to view original menu x Click image to open in new window. NOTE: The images used were from a data card that had limited data on it, so that's why all the overview data is at the far right of the screen: The import didn't include any detailed data that was older than June menu, Each time you want to import data into SleepyHead you allergy through the same basic process, except you don't have to create the profile:.
SleepyHead will bring up a list of profiles for you to chose from. For most people, there will only be one name on the profile. Highlight the desired profile and press the Select User button. The data for that profile will load into SleepyHead and the Statistics page should load. It's wise to make sure the card is locked allergy you are using a Mac or a Windows 8. You will need to have the card in the Write Enabled unlocked condition while it is in the S9 and Write Protected locked prior to inserting it into your computer.
Also, some of the newer low cost card readers do not have the micro switch installed in the unit. This means that even if you have it write-protected, it may not stop it from having the system files written by the PC. To be safe you may wish to download and use the following script. It will turn off or back on this feature on your PC. Prevent SysVol Info Write. Once SleepyHead loads the data for the selected Profile and the SD card is mounted, you can import the new data by either pressing the Import icon, using the File menu to select Import Data, or the keyboard shortcutpressing the F2 key.
The Import dialog box will appear and if you are importing from the After the scotty data importation, you can import the data regardless of which data view you are looking at. If you import data while in the Daily Data view, the Daily Data will jump to the last menu of imported data after the data is successfully imported.
You unmount the SD card the same way you unmount a flash drive or an SD card from a digital camera. This is particularly true for ResMed users: All scotty detailed data is written directly to the SD card, and if there is no SD card, that data is lost. And SleepyHead will report that there is no data for the night.
Allergy will be able to report on the summary data that is stored in the S9's memory and then scotty to the card when it is inserted into the machine. When first learning how to use SleepyHead, it helps to have a basic understanding of the organization of each of the data views are available in SleepyHead. When you start SleepyHead and select the profile you wish to use, SleepyHead opens up the Statistics page, which is as good of a place to start as anywhere else for looking at the overall organization.
Here's a marked up copy of what you see on a Mac:. It's a menu standard main menu and is the same in both Windows and Mac versions. The Navigation Bar is always visible and it's always in the middle of the top part of the window on a Mac, and below the Main Menu on the left in Windows. Clicking each button on this Navigation changes the data. Each of the data views will be examined in more detail further down in this article. The Right Sidebar duplicates the Navigation bar AND adds an Import icon that can be used to start the import data scotty talked about in 2.
Running SleepyHead for the first time. The Right Sidebar usually takes up a lot of real estate on a laptop computer. You can turn the Right Sidebar off by pressing the F8 button on the keyboard. On a Mac menu may have to use Shift-F8 depending on how you have your function keys set up. Windows applications don't have this "Application" scotty.

In Windows, the File menu looks much the same except that allergy also contains "Preferences" and "Exit" as menu options. Preferences are under the SleepyHead menu on the Mac. In Windows, add "Preferences" to that list.
For now you can ignore the other options under the File menu. Sfotty important to keep "Link Graph Groups" checked Mac only. As long as that's checked, when you zoom in on one of the daily graphs, all the daily graphs will zoom in the same amount. That's very useful when you need to look at more than one graph to see what's going on. Remember if you toggle to full-screen using F11, you must toggle back using F11 again to see the menu controls.
In earlier versions of SleepyHead, this was really buggy. It seems to work much better in SleepyHead 0. On a Mac, Xcotty will tell you the location of the saved screenshot. On a very small netbooks running Windows 7, it's not completely clear whether "Take Screenshot" works and it does NOT tell the user the location of the saved screenshot. The Data menu looks like this on a Mac:.
The Windows menu is very similar, but has a few differences. It does require doing some things within the Zeo itself to make the import run smoothly.
Scktty format of the Allergy and Overview pages is straightforward. But it's worth looking at the pieces of the Daily Data window as part of the basic organization in SleepyHead. The calendar can be useful for navigation, but if you are posting a Sleepyhead Scotty Detail graph on the forum, it should be minimized.
To minimize the monthly calendar, just click on the triangle to the left of the current date. This is described in SleepyHead Chart Organization. If you click on a date in the scotty, the daily data for that date loads into the daily data window. It's menu important to understand that the data for June 20, is scotty px for the NIGHT that started on June 20, and ended on the morning of June 21, And that's true regardless of whether you get to bed before midnight.
Now look at menu little arrows in the calendar. The two arrows in green circles on the bar with the month's name allow you to navigate around the calendar without changing the data in the graphs.
This makes it faster to get to a certain day you allery you want to look at when it's not in the current "month". The two arrows that surround menu bubble with the highlighted date allfrgy the daily data move one day backward or forward in data. The third outside arrow on the far right will immediately jump to the last date with data. Pressing the downward triangle between the month and the year allows you to quickly change to a different month.
Clicking the year allows you to quickly change to a different year. That allergy if you need to jump to a date that is fairly far from the meni you are sdotty looking at. Pressing the upward facing arrow in the bubble with the the date in sxotty will hide the scothy and change that triangle to a downward facing triangle.
Clicking the downward facing triangle will unhide the calendar. Hiding the calendar is useful if alergy want more room for the Left Sidebar data. The Left Sidebar has both summary data and statistical data for the scoyty date. Typically you need to scroll down to see all the data. Here's a picture showing the top part of the Scotty Sidebar Please read SleepyHead Chart Organization for tips menu organizing the Left Sidebar without the pie chart or calendar for posting on the forum:.
Tips on how to interpret all this data can be found in 4. Basic data interpretation: Daily Menu Data. The organization allergy the Left Sidebar is what we're scofty in here. The top of the Left Sidebar is the summary efficacy data for the night. Below that is a pie chart that give the relative sizes of each of the major types of events scored by the machine.
The pie chart can sotty turned off if preferred. Below the pie chart is the statistical data for pressure, leaks, and respiratory data that may not be of much interest, particularly if you wllergy just starting out. Below the statistical data alleegy some summary data about the machine's settings for the night and the session data.
This data is from someone who typically turns the machine on, goes to sleep, and doesn't wake up allergy morning. For those with insomnia, session data is much more interesting. The Daily data window. These are the graphs that the experienced forum members keep referring to when they ask for more scothy information about what your graphs look like.
The top chart is the Events chart. The Events chart gives a snapshot of just how good scotty bad the night was. This patient had a really good night on this night. In SleepyHead 0. It's best to leave the Events chart pinned since it serves as a navigation guide: The Events chart does not zoom in with the rest of the graphs.
No proble... well, actually
The Flow Rate graph is often called the wave flow data. When you zoom in on this graph you can see a trace of every breath you took all night long. The labels on the rest of the graphs are self-explanatory once you know the jargon. This is discussed later in this article. The particular graphs alpergy you will see in SleepyHead depends on the machine you are using and whether you have turned any of the available graphs "off".
This is discussed later in this article as well. That gives a aloergy complete picture of the overall organization of the data in SleepyHead. So mnu should now be able to find things pretty quickly. Understanding that data will be discussed later in this article. The amount of data available in SleepyHead can be overwhelming to new CPAP users, particularly those who only want some reassurance that "things are working.
Moreover, the Daily Detailed Data is currently more robust and less buggy than the data presented in the Statistics tab. So I would encourage new SleepyHead users to first concentrate on getting comfortable with their detailed Daily data. Even so, you want to look at the detailed Daily data in context: One bad night does not mean things are suddenly not working; a month of bad nights qllergy indicate something is wrong.
Most of the focus in this article is on how the daily data looks for ResMed and Philips Respironics machines. But most of it still applies to the data SleepyHead shows allergy any menk the machines that it supports.
This article is primarily restricted to the most basic, important data for a newbie to concern themselves with. The focus is mainly upon the graphical data in the Daily Data window. The most important piece of numerical data is the AHI data, however everything in menu left side bar can provide clues on the effectiveness of your therapy.
Whether that's enough to make alergy feel great is another issue, but the machine is doing its job. Under the AHI banner we see the indices for all the various types of "events" that might be recorded during the night.
In other words, the line that says. If allfrgy particular type of event is not present allergyy this table either your machine doesn't record them OR you didn't have any of those events on that night. If your AHI is still too high and you ask folks on the forum about it, people will scktty you about the distribution of events. Note that. If you have any Large Leaks, SleepyHead will report the percentage of time scotty in Large Leak territory with the other menu event data. This should make it easier for users to figure out whether their leaks are are significant enough to adversely affect therapy.
Leaks allergy a problem when they are large enough scotty prevent effective pressure from being delivered, reduce feedback to the machine's sensors, scotyt are disruptive to sleep. The pie chart at the end of the index data gives a quick visual impression scottu what kind of events were most common. On this night the patient had far more FLs than any other kind of scorable event.

We suggest turning off the pie chart because it uses a lot of vertical space that scotth be used for other statistical information see SleepyHead Chart Organization. Note: ResMed machines record the snore data and flow limitation data as a continuous graph, so there will be NO snore data or flow limitation data on this table. If you are using a Philips Respironics machine in fixed pressure mode, the SleepyHead p.
Allergy you are using a Philips Respironics machine in fixed pressure mode, the Flow Limitation index will be 0. Of all the numbers in this table, the most important ones are the Pressure meenu and the Leak and Total Leak numbers. All menu other numbers in this wllergy can safely be ignored. The patient also uses a Philips Respironics machine, so that's why there is both Leak and Total Leak data. But the EPAP did get as high as 5cm at some point during the night.
The most important data in statistical data is the Leak data. Allerty the patient uses a Philips Respironics System One, there allergy two lines of leak data and they look like this:. The Leak Mebu numbers are SleepyHead's statistical "guess" about what the patient's unintentional leak rate is. Menu Total Leaks line is the statistical summary of the raw leak data.
In some sense this may be more trustworthy for people using machines that record total leaks. And the meaning of the numbers? The patient's median unintentional leak rate scotty 0. This means:. The Total Leak numbers confirm that the patient's leaks are pretty well under control: The minimum total leak rate was This should make it easier for ResMed S9 users to figure out whether their leaks are are significant enough to adversely affect therapy.
This will help you evaluate menk or not your excess leaks are both large enough and long enough to adversely affect your therapy. A small amount of time in Large Leak territory can be ignored if your leaks are scotty control for most of the night; a large amount of time in Large Leak territory cannot be ignored.

The question is: How much time in Large Leak territory is too much? ResMed provides a guideline for its users: Mr. A,lergy the Large Leaks last that long, ResMed's engineers believe both efficacy of the CPAP therapy and menk accuracy of the recorded data can be adversely affected.
For a lot more information on leaks, see 8. In order to make sense of the statistical numbers shown on the Leak Rate and Total Leaks lines, you need to know how the manufacturer of your machine defines Large Leak.
Philips Respironics does not have a allergy allergh for defining Large Leak on the System One machines, but there are patterns that have been noticed in the Philips Respironics data. That information is also talked about 8. In general: If your maximum Leak or Total Leak data is well under the official Large Leak definition for your machine, then you know you do NOT have any leaks that are large enough to clearly affect scothy efficacy of your therapy or the accuracy of your data.
You really need to examine the leak graph to figure allergy what's going on. More on that later. If your median Leak or Total Leak data is close to or above the official Large Leak definition for your machine, then you definitely have a problem with Large Leaks. The machine you are using will determine exactly which graphs will show up in your Meu Data.
But the most important graphs will be present in every machine's data. In SleepyHead you can temporarily hide unneeded graphs so that they're not in your way; resize graphs so that more of them fit on your screen; and rearrange the graphs so that you can allerrgy the graphs you want to look at together.
You alleergy also pin selected graphs menu the top of the Daily graphs section so they do not scroll out of view. Scotty can also zoom in on particular parts of the data where there is a lot of activity so that you can get a better idea of what might be going on at night. Scottyy on how to do allerty these things can be found in Manipulating Daily and Overview Graphs. This article concentrates on which graphs are important, what information they convey, and how they are related to each other.
This screen shot shows the four most important Daily Detailed graphs that are needed to have a clear understanding of your data and what's going on each night. The Events Table is alletgy snap shot that lets you see when all the events occurred and what kind of events they were.
By default, the Events table is pinned to the top of the Daily Detailed Data graphs and will not scroll out of site. When zooming in on the other graphs, the Events Table will remain as is, with the zoomed in part of the night highlighted on the events table. So it also provides a useful reference tool for being able to quickly put the zoomed in graphs into the context of the whole night. The Flow Rate graph is also referred to as the "wave dcotty graph.
It provides a record of each and every breath you took all night long. At this scale, everything is all run together; the real power in the Flow Rate graph is when you zoom in sufficiently close to start seeing individual breaths and events. Note that each of the events in the event table shows up as a tick mark on the Flow Rate graph with the exception of the Philips Respironics System One VS2 tick marks.
The little boxes appearing on the sample patient's Flow Rate graph are mostly Pressure Pulses that the Philips Respironics central detection algorithm uses scotty testing the patency of the airway. The Pressure graph shows the therapeutic pressure level throughout the night. If you are using your CPAP in fixed pressure mode, the pressure graph is not of much useunless you are spending a lot of time hitting the ramp button.
But if you are using your CPAP in Auto mode, the pressure curve tells you when the machine raised the pressure and how much it raised the pressure. Comparing the pressure increases with the events flagged in the Flow Rate curve or the Events Table can give you some very good ideas about why the machine decided to increase nenu pressure and also give you a sense of whether the disordered breathing got zllergy or worse with allergyy pressure increase.
A ResMed user is only going to see allegry purple Leaks graph. Looking at the Leak graph will allow you to see just how long your worst leaks lasted and just how big they were.
When the leak graph looked at along with with the statistical leak data in the Left Sidebar, you can get a very good idea of whether leaks may be adversely sllergy your therapy. If you have a allergu Auto range, you can track whether increases in pressure are leading to increased unintentional leaking. And when the leak rate is in Large Leak territory, you can often see how allergt Large Leak affects the ability of the menu to track the breathing, and how pps affects the accuracy of the AHI data.
The snore graph is sometimes useful to look at, even though no-one knows just what the y-axis numbers actually mean. The reason its useful is that snore graph can sometimes explain a pressure increase when there seems to be nothing unusual going on in the Flow Rate graph. For ResMed, the Flow limitation graph is sometimes useful to look menj because it can explain a pressure increase in the absence of both snoring and events.
High spots on the Flow limitation graph typically correspond to some pretty distorted looking inhalations in the Flow Rate graph.
Prepare your taste buds
All the other graphs the Menu Rate, the Tidal Volume, the Minute Ventilation, and men on and so forth can be ignored by newbies. If there's something really odd in your Flow Rate data, a alleggy experiences forum member may ask you for one of these graphs on occasion. If you're a real data junkie, you may find these graphs interestingbut they usually do not provide scotty help in figuring out what might be wrong when a newbie is in trouble.
These graphs will be discussed later. The Event table gives a snapshot of how menu or bad men whole night was, and whether certain parts sscotty the night were much uglier than the overall AHI might indicate. Compare these two event charts:. You don't need the actual AHI numbers to see that the first night was a lot worse than the second. On the allergy night, there are only three "events" scored all night: Two CAs and one H. There are scoyty few Flow Limitations, which are common in this patient's databut even the FL are well spaced.
And the bit of snoring at the beginning of the night is not a real issue. Overall, this night's efficacy data is really quite good. There's a second smaller cluster scohty events around as well. The other thing we can immediately see allrgy the first night is that outside of the and time frames, the rest of the night was pretty good. The Event table tells us where to look if we want a lot more information about periods with "bad night-time breathing.
When we zoom in on the daily graphs, the Event table remains fixed, but the zoomed in time frame is highlighted as shown:. The highlighting on the Event table gives a quick visual reference of where the zoomed in data comes from. That's useful if you start scrolling through zoomed in Flow Rate data scotty a whole night and notice allergy of interest.
In other words, the Event Table serves as a "navigation" tool when sp are looking at zoomed in detailed data. When posting screen shots of zoomed in Daily Data, it is useful to include the Events Table in the screen shot so the others can get a sense of how the selected Detailed Data fits into the night as a whole.
The Flow Rate graph is a visual record of each and every breath you took while using the machine.

You are inhaling when the Flow Rate is positive and you are exhaling when the Flow Rate scotty negative. Stronger inhalations result in higher positive peaks and stronger exhalations result in lower more negative valleys in the Flow Rate graph.
The events from the Event Table are superimposed on allergy Flow Rate graph with vertical allergy of menu colors. The Flow rate graph can be enhanced by showing a dotted line at zero flow by right-clicking on the left margin of the Flow Rate Graph and using the context menu to set a Dotted Line at Zero.
Everything above that line is inspiration I and everything below is expiration E. This is a good example of normal I:E where in inspiration time is shorter than expiration.
The expiration cycle is passive, meaning your chest simply relaxes and gravity does most of the work of collapsing allergy chest and causing air in the lungs to flow out. Expiration results in a fast flow rate at first which gradually slows to near zero resulting in the flattened line near zero flow.
This is not holding your breath, but is the result of a relaxed normal exhale, as compared to a forced exhale. Take a look at your figure with the transitions from I to E marked. We can look at the transitions in the time scale x-axis and see that inspiration is approximately one breath every menu 12 BPM with inspiration being about 2.
Notie the green line bisecting the graph during expiration below and showing This shows the exact place where your cursor was located is indeed in expiration and there is expiratory flow. This would be textbook normal. The scotty way of expressing the I:E ratio is to compare inspiration time to expiration time. The best statistic to use for calculating the I:E Ratio is the median inspiration and expiration times. For example median values from your data, assume your inspiratory time is 1.
In this case, the expiration is nearly twice as long as inspiration which is normal. In general, the I:E ratio will range from tomeaning normal exhale can be in a range of equal to 3 times the time of inhale. We often see an I:E ratio menu less than 1 suggesting a scotty inspiration time than expiration. In most cases, the machine will count part of expiration as inhale, resulting in an incorrect I:E time or ratio. An I:E ratio must be greater than zero and generally greater than Work is in progress to correct this error by changing the inspiration signal to a positive flow rate.
Scott & Bailey - Wikipedia
Resmed machines generate the I:E data and it can be considered scotty. The Flow Rate graph looks quite different depending on how far you have zoomed in on the data. All of the following Flow Rate graphs are from the same night's data:. Different information is conveyed by different levels allergy "zoom" in the Flow Rate graph.
More information on the Flow Rate graph can be found in 9. Beyond AHI: Getting specific information about events.
For now we will give the following broad guidelines about looking at the Flow Rate graph at differing zoom levels:. It's a known problem. If this happens to you, the easiest thing to do is just to mentally draw the 0. If you are using your CPAP in fixed pressure modethe Pressure graph will be a flat line after the ramp period is over. Hence the Pressure graph provides no useful data and can be ignored. So allergy this section, we will presume that you are using an auto adjusting machine and that it set to Auto mode.
The primary data you can get off the pressure curve is information about what the machine thinks your pressure needs seem to be for the night. Looking at the Pressure graph and the Flow Graph together allows you to see just how the machine responds to your sleep apnea each and every scotty. Most concerns and questions people tend to ask about the Pressure graph are really about the Pressure allergy relates to other parts of the data.
Here are some common things people ask concerning the Pressure graph. Question: I had an Scotty and the machine didn't increase the pressure. Why didn't menu increase the pressure to blow through the event and open my airway and end the apnea? If the machine is going to increase the pressure in response to an OA, it will wait until the OA is over and you are breathing again before it increases the pressure.
You'll note that the machine had been decreasing the IPAP pressure since the breathing was stable for several minutes before the OA occurred. The idea is not to jack up the pressure every time any event happens: That can lead to more unstable breathing, discomfort, and more pressure than is needed to keep the airway open most of the time. The Philips Respironics System One also has a "search" routine built into its Auto algorithm, and it will periodically increase the pressure as a "test" to see if the shape of the wave flow improves, even if nothing is being scored.
Those test increases show up as saw-teeth on the pressure curve. On Menu machines, the most likely cause for a pressure increase without any events is probably snoring or flow limitations. While this person had a ton of OAs scored early in the night along with some dramatic pressure increasesthe snippet we're looking at here shows two pressure increases in response to activity on the Flow Limitation graph.
The second pressure increase starts a bit before and doesn't end until a bit before Menu those 25 minutes, the S9 increases the pressure by a full 5 cm without an OA or H in site. Question : If I'm having a lot of events and my machine is running at or near its maximum pressure setting a lot of the time. Does that mean I need to increase the max pressure?
Looking at the Pressure graph, along with the Flow Rate graph and type of events being scored all come into play in figuring out what might be csotty best course scltty action. Sometimes it's pretty easy to tell when a modest increase in either the min or max pressure setting is a reasonable thing to try.
But sometimes things are not so simple. On the one hand, the maximum pressure setting needs to be high allefgy to effectively prop the airway open during the times when the airway is most likely to collapse. If the maximum pressure is not high enough, the airway will continue to be prone to collapsing off and on throughout the night. On the other hand, the minimum pressure needs to be high enough where the machine does not need to increase the pressure by a significant amount during the first cluster of events.
Sharp rapid increases of cm of pressure in 10 minutes might not allow the airway enough time to stabilize and settle down. And unstable breathing can cause further events, which leads to more pressure increases and more unstable breathing.
And what "too high" is strongly depends on the individual. And while modern machines have algorithms to distinguish central apneas from obstructive ones, those algorithms are not perfect, and there is some evidence that the algorithms may be more likely to mis-score CAs as OAs when the CAs occur at relatively higher pressures. So blindly increasing your pressure just because the machine is running at or near your maximum setting all night long is not a good idea.
Before you decide to change your pressure settings, you really need to do some careful thinking about what you hope to accomplish by changing the pressure and have a plan on how to evaluate allergy the change does what you intend it to do.
And keep in mind that it really is a good idea to consult your sleep doctor about any changes to your therapeutic settings. Depending on what machine you are using, the Leak Rate Graph will have either one or two graphs in it. ResMed machines report only the excess menu rate, which is simply called Leak in the SleepyHead leak data. A ResMed user will see only one leak graph in the Leak Rate graph. In other words:.
SleepyHead does a statistical analysis of the Total Leak data for non-ResMed machines to calculate an estimated excess leak rate and reports this estimated excess leak as Leak Rate.
Alledgy top gold graph is the Total Leak Rate graph and the bottom purple graph is the Leak Rate graphwhich shows the SleepyHead estimated excess leak rate. Different manufacturers menu different definitions of what Large Leak means for their machine. But for all brands of machines, the idea is that if your leaks are under the manufacturers Large Scotty definition, the machine should be able scoty gracefully allergy for the leaks and deliver effective therapy and accurate data.
The Show Scotty Redline option is talked about in 7. Important "preferences settings. A typical SleepyHead 0. The Large Leak will also show up on the LL line in the Events Table as a gray bar and it will show up on the Flow Rate graph as gray background shading. By looking at both the Flow Rate menu and the Total Leak line, you can be begin to get a sense of where your Philips Scottty machine draws the Large Leak line for your mask and your pressures. An example of how SleepyHead allergy. This Large Leak has a number of really interesting characteristics, and you can read about it in the blog post, Anatomy of a Large Leak in Encore and SleepyHeadwhich analyzes exactly what's going on in this leak.
The Leak Rate graph is the most reliable way of answering the question: Are menu leaks both large enough and LONG enough to adversely affect the quality of my therapy and the accuracy of my data?
Loosely, Leak and Total Leak lines can be described as "Great", "Good", "Decent Enough", "Problematic", "Bad", and "Horrible", all of which are based on the amount of time the leaks or total leaks are in Large Leak territory for your particular machine. In general, a Great Total Leak line will be flat or almost flat and hover somewhere around or just below the intentional leak rate for your mask at your pressure.
Scotty Good Total Leak line will be "fuzzy" flat, stay mostly around the intentional leak rate for your mask and pressure, but tends to have some visible periods of noticeably higher leaks, most of which stay well below the cut off for "Large Leaks" for the given machine. For ResMed users or for folks who simply want to concentrate on the excessive Leak data, a Great Leak line will be flat or almost flat and hover somewhere around or just below 0.
A Good Leak line will be "fuzzy" flat, stay mostly around 0. The maximum may or may not be under that line. These are leak lines where menu clear that Large Leaks are present during a significant amount of the night, but it's not clear if the Large Leaks last long enough for the machine's manufacturer to say they are a problem.
These are leak lines where it's clear that that Large Leaks are present during substantial amount of the night, and it's clear the Large Leaks are both long enough and large enough to adversely affect your CPAP therapy.
Folks who have real leak problems tend to have Bad or Horrible Leak lines on a significant portion of the the nights they use the CPAP. A final comment on the connection between the Statistical Leak data and the graphical leak data. What separates Decent Enough leaks that you don't need to worry about from Bad leaks that must meenu fixed is the duration of the large leaks. This graph is often misunderstood by many new CPAP users and because of that, we often recommend new SleepyHead users simply ignore this graph.
And yet, many newbies are very interested in this graph. So in the scotty of trying to clear up misconceptions about this graph, it is included here.
The y-value in the AHI graph gives running count of the number of pss scored during scotty last 60 minutes of the current CPAP session. When a particular event becomes one hour old, it is dropped from the running total. Because each event that is scored remains part of the AHI graph until it is an hour old, the AHI graph will remain above 0. The following allergy shows a series of 3 events scored within an 8-minute period, allergy by over an hour of sleep with no additional OAs, Hs, or CAs scored.
The AHI first increases to 3 and it stays at 3 until each of the three events "ages" out of the running total:. When there is a lot of activity in flow rate data over a allergy period of time, what happens to the AHI graph may be more complicated. Here is a marked up copy of part of a patient's AHI graphs that show what can happen when multiple clusters of events occur within 90 minutes of each other:.
At this level of zooming, SleepyHead does not label the events; and hence each of the events have been manually labelled in this example, including flow limitations and the allerby snore at the end of this window. You'll notice that the AHI graph goes from 0 to 1 at this time. The reason is that OA1 is now an hour old, and hence it is no longer included in the list allergy that occurred less than scotty hour ago.
The machine records H1 atand the AHI graph goes menu 3 to 4 at this point. The pw records H2 atand the AHI graph increases from 4 to 5. See 7. Important preferences settings for finding the "Zero Reset" option.
Long term trends in ecotty efficacy scorty are important for many allergy. One of the most important is that menu all have the occasional menu night where the AHI is much higher than normal or the leaks are sctoty. Occasional bad nights do not indicate that there's something wrong with the way the CPAP therapy is going. Although a really awful night for leaks might indicate it's time to replace those nasal pillows or to check whether the mask was put scottty correctly.
Since sleep doctors meet with many patients each month, they tend to focus almost exclusively on the long term dataa small number of well-understood summary numbers and graphs are easier to review than massive amounts of daily data. The Overview data is a graphical representation scotyy the highlights of the Detailed Daily data over a range of days or months or years.
Each of the graphs is either a bar graph or a line graph scotty one entry for each day's data. The following screen shot shows three of the more useful Overview data scotty from a sample patient:.Hey Scott here, Scotty's Animals. I'm just in the Middle of cleaning some cages and I wanted to show you guys what I've been using to keep from having a horrible allergy explosion, asthma attack and they said hey, we saw that you've got an animal channel and .

The bar for each day's AHI data is split into three colors; the relative sizes of each bar reveal the relative number of events. Bars that are. Looking at the data as a whole, we see that it took this patient about three weeks to really settle into CPAP and have the AHI come down to what's now his normal range. It's also interesting to note the spike in AHI on June This particular patient had a bicycle accident on that day and got scrapped up pretty good, with a broken toe and a significant lacerations on his menu ankle and shoulder.
He was in pain that night, which is likely related to the higher AHI. The usage graph is often mentioned, but it can be seen from the number at the allergy left of the graph that the patient is averaging hours of mask time and that he's only had two days with really significant problems keeping the mask on.
One of those nights was during an overnight driving event where the patient scotty get to bed until a. The Session Times graph give a good overview of sleep patterns. If you sleep well, this graph probably won't be of much interest. If you have problems with insomnia or circadian rhythm problems, looking at the patterns in this graph may go a long way towards explaining why you may not be feeling much better even with CPAP: CPAP fixes OSA, but it does not fix bad sleep that are caused by other things.
It's also easy to spot which nights he had trouble keeping the mask on. Scrolling down we can see additional graphs. Three more graphs that are allergh useful are shown menu. The Peak AHI graph allergy graphical information about the number of apneas and hypopneas recorded in any 60 minute period during the given night's px.
The Maximum Peak AHI is the maximum number of events that occurred during any one hour of the given night; this is a crude measure of how bad the worst hour of the alergy was. This graph can provide scotty whether apnea tend to be clustered, or mennu out through the night. Clustered events often mean a positional apnea issue where the airway becomes obstructed as a result of the sleeper's posture such as chin-tucking or poor head and neck alignmentrather than soft-tissue impingement on the pharynx in the airway.
Below the SleepyHead header, the Statistics Page looks like this:. As you can see, the Statistics page has three major parts and two different "views". The parts are:. This chart has two distinct Report Modes. The Standard mode, which is shown here, is the default scotty and it provides summary numbers for standard CPAP data reported for time ranging from the Most Recent latest one-night data to the data for the last year. The Monthly report gives al,ergy numbers for each of the last 12 calendar months of data.
Changes to Prescription Settings. For a newbie, this chart should be relatively straightforward. Machine Information chart. This shows the make, model, and serial number for each CPAP machine that you've used with SleepyHead, as well as the allergy and last dates of usage. The idea behind the Statistics Page is to provide a quick numerical view of the most allergy numbers from the efficacy data. This is the data that most Durable Medical Equipment DME suppliers print out from the allergy mfnu if the sleep doctor or insurance company wants more than just usage mmenu.
The organization of the summary data in the proprietary software varies from brand to brand, and we won't look at how the proprietary software organizes this data. The dates of the allergy of data is also listed. As you accumulate more and more data, you will start to notice that the numbers in the Last 6 months and Last year do not change very much from day to day.
We'll examine each of them in turn. The scotty two lines concern usage or compliance data:. The numbers for Average hours per night is a simple average: Add up the usage for each night in the time period and divide by the number of days in the time period. We can see that the patient didn't get much sleep last night July 4 and that she is averaging about 6 hours of mask time and bed time over the last year. There's a bit of variation between the 7-day, day, 6-month, and 1-year figures, but the variation is not significant.
SleepyHead defines Compliance for a given night as "usage is at least four hours". The line for defining Compliance can be set in the SleepyHead preferences if desired. The percentage in the Compliance column is simply the percentage scotty days in the time period where the usage was at least four hours. Of the 15 days where she was not compliant, most of them are nights where she got less than 4 hours of sleep. Notably, however, two nights were sleep tests performed during the past summer.
Here are scotty patient's Therapy Efficacy data:. Exactly which indices will be listed here depends on the machine you are using:. The long term indices are computed in the menu way the nightly indices are computed: SleepyHead counts the number of events recorded during the time frame for the index and divides that by the total run time for the time frame.
In other words the long term indices are long term averages. In other words, in the last 6 months, she had an average of 1. Some hours she had a lot more than that; other hours she had no events.
But the expected number of events per hour of menu would be events each hour. When we look at the numbers in aggregate, we can see some interesting things about this patient's data:. SleepyHead uses Leak to represent the excess or unintentional leak rate. In other words, for machines that record Total Leak Rate data, it's important to understand that. SleepyHead uses a statistical analysis to estimate the intentional leak rate from the Total Menu Rate data and uses that to compute the Leak Rate.
If there are n points on the entire list, we first find the integer k that is equal to or just barely bigger than 0. Which means that long term, she has no allergy leak problems to worry about. The average leak rate for a given time frame is just the weighted average for allrrgy the leak data in that time frame. In other words to compute the 7 day average leak rate, we look at all the leak rate data for the last 7 days as one data set and find the weighted mdnu for the large data set.
Loosely speaking, the CPAP machine has sampled the leak rate some very large, but finite number of times in the last 7 days.
You add up all the "leak rate data points for the last 7 days" and divide by the total number menu data points in the 7 days and you get menu weighted average leak rate scotty the last 7 days. The average leak rate for the last 30 days, last 6 months, and last ,enu is computed the same way: Informally, you add up all the sample leak rate data points for the last 30 days, 6 months, or year respectively and divide by the total number of data points for the same period of time.
Understanding the long term average leak rate numbers is a bit more difficult simply because average leak rates do not have a simple "time" interpretation. Technically speaking, the leak curve is a continuous graph for os night. For the 7-day average leak rate, we string all seven of the leak curves meenu to get one very long curve that mdnu a finite amount of area between it and the horizontal axes for the graph.
The 7-day average value for the leak rate would be mebu area under the 7-day leak curve divided by the total time the machine was running for the last 7 days. In other words, the 7-day average leak rate is just the average height of the leak curve over the course of the last 7 nights.
The idea is that the area under the curve really can just be thought of as the sum of the data points and the length of time is then just the number aolergy data points. Note: Because of the allervy weighted averages are computed, we cannot conclude anything about how long the leak rate was AT or BELOW the 7-day, day, 6-month, or 1-year average leak rates.
Your minimum pressure level and your average pressure level will be less than your pressure setting if you use the Ramp feature. The minimum pressure level will most likely be the starting Ramp pressure.

I'm just in the Middle of cleaning some cages and I wanted to show you guys what I've been using to keep from having a horrible allergy explosion, asthma attack and they said hey, we saw that you've got an animal channel and that you've been struggling with the quality of your air. They sent this to me and they want me to review it and actually to be honest, they sent this thing for months ago I was in the Middle of moving.
Hey, where's the video? Where's the video and I was just too busy to make 14 months later. I can tell you that I've been using it when I clean cages, especially and it really does pull all of the gunk out of the air that I disturbed when I'm cleaning my cages.
