Many of the interfaces or masks were initially used in patients with obstructive sleep apnea before they were adapted for use in patients to provide noninvasive ventilatory support. Be aware that the list and indications continues to change as more experience is accumulated in these and newer conditions. Regardless of whether you are using a Mac or a Windows computer, the Preferences panel will look the same. [Medline]. If you make a mistake, you can edit the profile later. Occasional bad nights do not indicate that there's something wrong with the way the CPAP therapy is going. These are the graphs that the experienced forum members keep referring to when they ask for more specific information about what your graphs look like. Wijdicks EF. What is the role of noninvasive ventilation (NIV) in the treatment of chronic obstructive pulmonary disease (COPD)? 1994 Aug. 22(8):1253-61. 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. Your CPAP does not record EEG data, which is needed to determine night time wakes. Randomized prospective trials comparing its efficacy with oxygen were not conducted for almost 50 years, and small trials also confirmed its effectiveness in correcting gas exchange abnormalities, even in patients with profound respiratory acidosis, with a general benefit of both a reduction in intubation rates and mortality rates. Rev Neurol Dis. Exhaled air dispersion distances during noninvasive ventilation via different Respironics face masks. 3 (4):e205619. Arentz M, Yim E, Klaff L, Lokhandwala S, Riedo FX, Chong M, et al. High-flow oxygen through nasal cannula in acute hypoxemic respiratory failure. Short brief spiky leaks are very likely mask movement leaks... brief refitting or minor movement. What to do next depends on which Windows operating system you have and how comfortable you are with some advanced features of the operating system. If the median Leak/Total Leak number is close to or above the the manufacturer's definition of "Large Leak", then you've got a Horrible Leak/Total Leak line. CPAP is probably the most effective mode, achieving a reduction in intubation rates and mortality rates, with a little less effectiveness noted with noninvasive ventilation (BiPAP). Ann Intern Med. Characteristics and Outcomes of 21 Critically Ill Patients With COVID-19 in Washington State. But a leak is a leak no matter where it is coming from, and the machine doesn't know where it is coming from. NOTE AND WARNING for WIN 8.1 and Win 10 USERS. The larger and more persistent the oscillations, the worse (and louder) the snoring is. So when are leak lines "good enough" to not worry about it? 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 group the graphs you want to look at together. Wang K, Zhao W, Li J, Shu W, Duan J. Whether that number represents the length the snoring went on or some kind of measure of the loudness of the snoring is anybody's guess. Continuous positive airway pressure (CPAP) treatment nearly eliminates TNP-detected night-time BP surge in patients with OSA. The percentage in the Compliance column is simply the percentage of days in the time period where the usage was at least four hours. Noninvasive ventilation reduces intubation in chest trauma-related hypoxemia: a randomized clinical trial. 2,56 However, the cardiovascular protection and BP-lowering effect of CPAP are not perfect, and a significant number of OSA patients on CPAP develop cardiovascular events. Ozsancak A, Sidhom SS, Liesching TN, Howard W, Hill NS. In addition, length of hospital stay was shorter in noninvasive mechanical ventilation patients (14 vs 21 d, P = .001); however, no difference in survival was observed. The panel looks like this: Note that there are going to be graphs on this list that do NOT show up in your particular data; that's because this is a master list of all the graphs for all the machines that SleepyHead supports. NOTE: ResMed S9, Philips Respironics System One, and Fisher & Paykel Icon machines record Flow Rate data if the card is in the CPAP machine during the night; the DeVilbiss IntelliPAP does NOT record Flow Rate data. A chart of failure risk for noninvasive ventilation in patients with COPD exacerbation. [Medline]. And for reporting snoring in SleepyHead, the snoring data was reverse-engineered from the Philips Respironics machines and the information on why Encore presents the snoring data the way it chooses to present it is pretty scarce... And when you start analyzing the raw snoring data the decisions Encore makes on how to present the snoring data seems bizarre from a statistical point of view. To identify a perfect leak line from Total Leaks requires a bit of knowledge: We need to know the expected (intentional) leak rate for the mask. Some of these values have been edited. While this is not assisted ventilation, it is at its most rudimentary level, is a form of noninvasive ventilation. 2001 Oct 1. Typically, however, Large Leaks are defined in terms of the Total Leak Rate for machines that report Total Leak Rate. Hellenic J Cardiol. [16] Others have had less success, grading sensorium using a Kelly score of 4 or more defined as a stuporous patient, only intermittently able to follow commands, and an average pH of 7.22, where the success rate was 55% in a group of 20 patients. [10, 11] : Loss of consciousness with respiratory pauses, Heart rate less than 50 bpm with loss of alertness, Hemodynamic instability with systolic blood pressure less than 70 mm Hg. The presence of snores can be a predictor of obstruction and cause auto CPAP and BiPAP machines to increase pressure. The lock switch on the SD card is a physical switch and not all SD card readers have a corresponding physical switch in them that recognizes and respects the SD card's lock switch. Bi-level users will have IPAP/EPAP data regardless of the brand of machine. 313 (23):2331-9. Fisher & Paykel Icons do record FL data It could be a SleepyHead bug. When we use a CPAP, our upper airway is part of a "semi-closed pressurized system" comprising the blower, the tube, the mask, and our upper airway. At the pressures used by the patient, the expected leak rate for their mask is about 20-29 L/min. SleepyHead 1.1.0 runs on Windows XP, Vista, 7, 8, and 10. The question is: How much time in Large Leak territory is too much? For now you can pretty much ignore the Tidal volume numbers. But our CPAPs do not have any EEG data to work with, and any time the Flow Rate meets the manufacturer's definition of an apnea or hypopnea, the machine will score the event. So you should now be able to find things pretty quickly. They vary from person to person (based on size) and during solid sleep they are typically lower than when you're awake. For ResMed users or for folks who simply want to concentrate on the (excessive) Leak data, a Good Leak line will be "fuzzy" flat, stay mostly around 0.0 L/min, but tends to have some visible periods of noticeably higher leaks, most of which stay below 10-15 L/min. A systematic review of the literature. If this happens to you, the easiest thing to do is just to mentally draw the 0.0 L/min line half way between the peaks and valleys in the Flow Rate graph and use that to measure when you are inhaling and exhaling. The RERA algorithm probably flags things that aren't real RERAs and it probably misses some real RERAs as well. AVAPS uses an internal algorithm to make changes in the pressure support supplied to achieve the target volume, but these changes are small and occur over minutes (typically 1-2.5 cm water per minute). 148 (1):253-61. We have no idea. In mechanically ventilated patients with severe ARDS and hypoxemia despite optimization of ventilation, use of recruitment maneuvers is suggested over not using recruitment maneuvers. Because the breathing pattern is barely there, it's almost impossible for the machine to detect enough of a decrease in airflow to trigger flagging an OA or a CA or an H throughout the Large Leak (and even in the part of the longer, not-quite-so-large leaks immediately preceding and following the official Large Leak itself.) The 90% (or 95%) leak numbers, however, may very well be larger than the official Large Leak definition. 121(4):1149-54. But sometimes things are not so simple. But for the rest of us? It's not certain as to why this patient has both. Noninvasive ventilation is effective in patients with CHF. And the meaning of the numbers? (There's some debate between CPAP users of just how long the Large Leaks need to last before they become problematic). In general a Total Leak line will be mostly "fuzzy" flat and 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. This data is from someone who typically turns the machine on, goes to sleep, and doesn't wake up until morning. This article is primarily restricted to the most basic, important data for a newbie to concern themselves with. [Medline]. In a retrospective cohort study of 26 healthcare workers who developed SARS, 38% had exposure to noninvasive ventilation (NIV), whereas 8% were exposed to high-flow oxygen, but neither modality was identified with increased transmission of SARS in a logistic regression model. (ResScan will be able to report on the summary data that is stored in the S9's memory and then written to the card when it is inserted into the machine). Investigations with less severely affected patients did not demonstrate any benefit in any of these outcomes. It is the focus of this review. Between the Calendar and the AHI table in the standard view of the Daily Data table there is a navigation menu that looks like this: Clicking on the Events tab changes the look of the Left Side Bar; once Events is selected, the Left Side bar looks like this: You will notice this is a list of the kinds of events that were recorded for the night. Patients with the following diagnoses who may be candidates for noninvasive ventilation should be evaluated on a case-by-case basis: Neuromuscular respiratory disease The reason is that there's not enough data to accurately calculate the over night numbers if there are multiple sessions. Other diagnoses are regularly added to the list as experience accumulates. 2005 Sep. 128(3):1657-66. When the Flow Rate is negative (below the horizontal line labelled as 0.0), the air flow is going out of the lungs and you are exhaling. What are the minor criteria for intubation of patients using noninvasive ventilation (NIV)? Risk factors for SARS transmission from patients requiring intubation: a multicentre investigation in Toronto, Canada. Part II: Are my leaks bad enough to worry about? Profiles And that's ok: If the nightly AHIs are almost always below 5.0 and you're feeling well, there's really no need to look at the detailed data available in SleepyHead about each and every event the machine recorded over night. This is important because: Important Note for users of earlier versions of SleepyHead What are the benefits of average volume assured pressure support (AVAPS) in noninvasive ventilation (NIV)? Use of a continuous infusion of neuromuscular blocking agents is suggested in the event of persistent ventilator dyssynchrony, a need for ongoing deep sedation, prone ventilation, or persistently high plateau pressures. It's worth noting that some brands of APAPs are very aggressive in how fast and how far they increase pressure in response to snoring or flow limitations. Respiratory insufficiency due to cardiogenic pulmonary edema or congestive heart failure (CHF) is another condition that is effectively treated with noninvasive ventilation (NIV). Is there any clinical significance to the length of the exhalations? But the most important graphs will be present in every machine's data. Effects of noninvasive ventilation with bilevel positive airway pressure on exercise tolerance and dyspnea in heart failure patients. Here's a close up of what sometimes happened when our sample patient lied in bed unsuccessfully trying to get back to sleep: In this data, it's clear that the patient never got soundly back to sleep not only because of the large number of (false) events, but also because she turned the BiPAP off and back on three additional times after the first wake around 8:10 before finally deciding to crawl out of bed at 9:00. Choosing the initial mode of ventilation is based in part on past experience, in part on the capability of ventilators available to provide support, and in part on the condition being treated. Will AHA Best Practices Reduce Cardiac ICU Complications? This runs counter to the commonly accepted notion that you loose all your therapy pressure any time you open your mouth while using a nasal mask: The amount of air you lose through an open mouth depends on a lot of factors, most notably the placement of the tongue. SleepyHead 1.1.0 runs on Macs running OS 10.7+. On an overnight PSG, a RERA is scored when there is evidence of increasing respiratory effort that ends with an EEG arousal. Development of positive-pressure valves delivered through tracheostomy tubes permitted the delivery of intermittent positive pressure during inspiration. We now turn our attention to using the Leak/Total Leak line to identify when Large Leaks are long enough as well as large enough to compromise the efficacy of the CPAP therapy and the accuracy of the data. 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) average for the large data set. BMJ. I am told that the F12 trick will work for SleepyHead 0.9.3 screenshots on Windows machines. As an example: The patient's 6th month AHI = 1.79. Manipulating Daily and Overview Graphs, 9. [Medline]. In Windows, the File menu looks much the same except that it also contains "Preferences" and "Exit" as menu options. But there is another problem a full efficacy CPAP machine faces when the leak rate approaches or stays in official Large Leak territory for any length of time: The breathing itself becomes more difficult to track. Increased exhaled air dispersion has been demonstrated in simulation studies with mannequins with the amount of noted dispersion increasing with higher applied pressures (IPAP 18 cm water). [Medline]. Effect of Postextubation High-Flow Nasal Oxygen With Noninvasive Ventilation vs High-Flow Nasal Oxygen Alone on Reintubation Among Patients at High Risk of Extubation Failure: A Randomized Clinical Trial. You still have to download (or import) the data into SleepyHead. Q: Is there a list of keyboard short cuts and mouse tricks for SleepyHead? An example of how SleepyHead 0.9.6 flags one patient's rare official Large Leaks is shown below. Take a look at your figure with the transitions from I to E marked. SleepyHead defines Compliance for a given night as "usage is at least four hours". Maggiore SM, Idone FA, Vaschetto R, Festa R, Cataldo A, Antonicelli F, et al. Francisco Talavera, PharmD, PhD Adjunct Assistant Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Received salary from Medscape for employment. What are the types of noninvasive ventilation (NIV)? You can easily get that off of Photobucket or Flickr when you are looking at the image. We'll examine each of them in turn. This requires evaluation on several levels, and it may involve a trial of noninvasive ventilation. There's a second smaller cluster of events around 8:30 as well. How can the role of noninvasive ventilation (NIV) after extubation be summarized? Different manufacturers have different definitions of what Large Leak means for their machine. : A Systematic Review and Meta-analysis. But if you are using SleepyHead 0.9.3 on a Mac, the F12 Sleepyhead screenshot shortcut will not work; however, you can use the standard cryptic Apple keyboard sequence to take the screenshot. Create screenshots of the data you want to post. When OA2 is scored at 6:17:21, the AHI climbs to 3. [41] In comparison, higher ORs were identified with tracheal intubation (OR, 6.6; 95% CI, 2.3-18.9) and manual ventilation before intubation also had an increased OR (2.6; 95% CI, 1.3-6.4). [Medline]. Chest. Notie the green line bisecting the graph during expiration below and showing -3.43 mL/sec flow. Wysocki M, Richard JC, Meshaka P. Noninvasive proportional assist ventilation compared with noninvasive pressure support ventilation in hypercapnic acute respiratory failure. If you're not feeling better in the daytime, the Large Leaks might be part (or all) of the problem. The Statistical Leak data for a Decent Enough Leak/Total Leak line will have a median Leak/Total Leak number well below the the manufacturer's definition of "Large Leak". mostly purple indicate the user had more CAs scored than other events. For facial and nasal pressure injury and sores, note the following: Result of tight mask seals used to attain adequate inspiratory volumes, Minimize pressure by intermittent application of noninvasive ventilation, Schedule breaks (30-90 min) to minimize effects of mask pressure, Balance strap tension to minimize mask leaks without excessive mask pressures, Cover vulnerable areas (erythematous points of contact) with protective dressings. If the SD card is not inserted into the S9 during the night, all the daily detailed data (including all the graphs) is lost; the S9 writes the detailed daily data directly to the SD card. 3) Remember to put the card back into your CPAP machine. For a new user that's the right choice. If the maximum pressure is not high enough, the airway will continue to be prone to collapsing off and on throughout the night. But there really is no way to tell for sure that clusters of events in your data are REM or supine sleep related. Loosely speaking, the CPAP machine has sampled the leak rate some very large, but finite number of times in the last 7 days. Noninvasive ventilation reduces the need for intubation, mortality, complications, and length of stay in patients with COPD. Cursor left and right keys scrolls the highlighted box. ), (Source: F&P InfoSmart Spec Sheet) This indicates that the patient's BiPAP could not reliably determine whether there was much air going into or out of the patient's lungs. For example median values from your data, assume your inspiratory time is 1.54 and expiratory time is 2.88. The 90% leak rates for 30-day, 6-month, and 1-year are found the same way: We line up all the data points for leak rate for the entire time period in increasing order. A Decent Enough Total Leak line has more obvious leaks than a Good one does, but line stays below the Large Leak line for at least 70-90% of the night. Also see the clinical guidelines summary, Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease. 290(22):2985-91. Right clicking on, and then dragging the currently selected highlight in the Event Table allows you to easily slide the current selected time "window" over the whole period. What are complications of both noninvasive (NIV) and invasive ventilation? Information about how ResMed, Fisher & Paykel, DeVilbiss define Large Leak can be found in 8. Get in Touch 5850 Coral Ridge Drive Suite 304 Coral Springs, FL 33076 877.456.3529 [50]. For more details about how SleepyHead handles Leak Rate and Total Leak Rate data see 8. Some investigators found no benefit with their applied noninvasive ventilation, and some noted more complications, specifically higher rates of myocardial infarction. Effect of Noninvasive Ventilation Delivered by Helmet vs Face Mask on the Rate of Endotracheal Intubation in Patients With Acute Respiratory Distress Syndrome: A Randomized Clinical Trial. It's also important to point out again that two of the three probable periods of mouth breathing in that last example stay below the ResMed Redline: In terms of the efficacy of the CPAP therapy, the two smaller mouth breathing leaks are not serious enough to worry about. There are considerable differences in opinion and controversy on the use of noninvasive ventilatory devices in patients with novel coronavirus disease 2019 (COVID-19). It is reasonable to consider this modality as a method of providing low-level positive pressure. The experience of high-flow nasal cannula in hospitalized patients with 2019 novel coronavirus-infected pneumonia in two hospitals of Chongqing, China. Philips Respironics, Fisher & Paykel, and DeVilbiss users will have TWO leak lines: One for Total Leak Rate and one for Leak Rate. Philips Respironics System One users will see everything on this list. But it's obvious that 3/5.53 is NOT equal to 1.1 and 4/5.53 is NOT equal to 1.1. Crit Care Med. [9] Lower ROX index scores not only identified those requiring intubation, but was also associated with poor outcomes, specifically mortality. Because of this variability it is not uncommon for OAs, CAs, and Hs to be scored during periods when you are awake: A few minutes of conscious deep yoga style breaths followed by a return to normal wake respiration may meet the criteria to be scored as an H. When we're tossing and turning in bed, it's not uncommon to hold our breath for a few seconds while concentrating on turning over or fixing the bed pillows and covers; if the pause in our breathing is close to 10 seconds, it can be mis-scored as a hypopnea. Courtesy of Therese Canares, MD, and Jonathan Valente, MD, Rhode Island Hospital, The Warren Alpert Medical School of Brown University. So a good working notion for a Problematic Leak/Total Leak line would be the following: A Problematic Total Leak line is one that is NEAR or IN the manufacturer's Large Leak Territory for somewhere between 20-35% of the night; A Problematic Leak line is one that is ABOVE 24 L/min for somewhere between 20-35% of the night. Such people often wind up with a diagnosis of upper airway resistance syndrom (UARS) instead of OAS. But by this point the leak rate has also grown to about 55 L/min and the BiPAP decides to flag this as an official Large Leak. Everything above that line is inspiration (I) and everything below is expiration (E). Hence early APAP Auto algorithms often were designed to NOT increase the pressure in response to apneas scored at pressures of 10cm or greater. What are potential complications of noninvasive ventilation (NIV)? If you hide the Calendar and turn the Pie Chart off in the Left Sidebar of the Daily Data, you can show all the needed Daily Data in one screen shot. The official Large Leak was scored as soon as the patient's BiPAP found a trace of her breathing pattern. Insert an image link in your post that points to the uploaded screenshot so that your image appears as part of your post. Mathematically these numbers seem to be the Inspiratory Time in seconds divided by the Expiratory time in seconds, but perhaps this is actually being reported as a "percent" In other words, these numbers may actually be computed as: [Wiki Editor note: FIX THIS IT MAKES NO SENSE OUT OF CONTEXT OF THE ORIGINAL POST THIS WAS PULLED FROM] And in that case the meaning of the weighted average is that the length of your average inhalation is about 40% of the length of your average exhalation. The maximum may or may not be under that line. The Photobucket link will automatically include the [IMG] and [/IMG] tags as well as a URL link. There are three different ways to Import the data: The Import Data menu item and the Import Icon are circled in the screen shot below. Tran K, Cimon K, Severn M, Pessoa-Silva CL, Conly J. 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. This leads initially to hypoxemic respiratory failure, and patients with CHF who further deteriorate manifest hypercapnic respiratory failure. 247(4):617-26. [Medline]. The labels on the rest of the graphs are self-explanatory once you know the jargon. But the calculation of the VSI index in Encore is not as straightforward as you would expect. Since the maximum leak rate was 14 L/min, we know that for at most 10% of the night the patient's leaks were between 10 L/min and 14 L/min. Perhaps the "magnitude number represents the length of time measured in (seconds? What other considerations may limit the use of noninvasive ventilation (NIV)? Trials of noninvasive ventilation are usually 1-2 hours in length and are useful to determine if a patient can be treated with noninvasive ventilation. Most of the time the flag is closer to the end of the event, but there is some variability. If you start breathing through your mouth, however, the tongue will slip from that position, and as the tongue moves down away from the roof of the mouth, more air will be able to leak out of the open mouth. But SleepyHead cannot use this summary data for anything on the Daily Data page, and hence if you forget to put the SD card back into your machine, you won't get the graphs. Chest. Also any other machine specific data: PB on ResMeds; SensAwake stuff for Icons; Expiratory Puffs (for either Icons or IntelliPAPs). Dry mouth may or may not mean that you are seriously impacting your therapy with mouth breathing. All these criteria are subject to some degree of interpretation in the context of the patient's clinical status. If you want to add a Redline to your Leak/Total Leak graphs in SleepyHead, our advice is to look at your own Large Leak flags and figure out where they seem to start. If you use Photobucket, you can simply copy and paste the IMG link into the editing window for the post. We will assume that 30% of the night in Large Leak territory is clearly bad news for users of any CPAP machine. 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. 2008 Jul 10. 2009 Apr. Like Minute Ventilation and RR, the Tidal volume varies from person to person. [Medline]. Your minimum pressure level and your average pressure level will be less than your pressure setting if you use the Ramp feature. 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. National Guideline Clearinghouse. Otherwise launch the BrokenGL version from the Windows Start Menu and verify that it works before placing shortcuts where you like. 2014 Aug 1. Important "preferences settings. For a new user of SleepyHead, the only item on this menu that you may need is the Purge CPAP data options under the Advanced menu item. Adjust the size, scale, and order of the graphs you want to post. But two or more OAs or Hs occurring close together indicates that the current pressure may not be sufficient to prevent the airway from collapsing in the (very near) future. 885066617740849. ResMed users will only have ONE leak line and it is Leak Rate. The blower has to add at least 25 Liters of air to the system each minute in order to maintain the desired pressure. Diaz GG, Alcaraz AC, Talavera JC, et al. The Official Large Leaks for a System One will NOT be flagged directly on the SleepyHead Leak/Total Leak graph. In another review, greater improvement in respiratory acidosis, hypercapnia, and tachypnea was noted after 1 hour on noninvasive ventilation, along with fewer complications related to intubation. 2020 Mar 30. Although the focus has been on noninvasive ventilation (NIV), there has been increasing use of high-flow nasal cannula (HFNC) oxygen in clinical situations where NIV had previously been used. And some people find themselves in the middle: Leaks sometimes seem to cause problems. 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. What are alternative ventilator interfaces to orofacial or nasal masks for noninvasive ventilation (NIV)? In Encore, the VSI on the right side of the Daily Detailed Data panel is reported as VSI = 1.1. Clicking the year allows you to quickly change to a different year. This is discussed later in this article. Noninvasive ventilation is an adjunct to weaning (substitutes noninvasive support for invasive support). The pie chart at the end of the index data gives a quick visual impression of what kind of events were most common. You'll notice that the AHI graph goes from 0 to 1 at this time. Its performance and role compared with NIV has undergone additional investigation. [Medline]. It's also possible to snore on both the inhalations and the exhalations; in that case the oscillations appear on both the inhalation and exhalation parts of the flow rate curve. This system is very good at preventing apneas and hypopneas from occurring, but it is not perfect: A few events will likely occur each night, but the overall number of events will be low enough to keep your treated AHI under 5.0, and probably well under 5.0, each night you use the machine. If you are wondering whether the clusters indicate that you need to change the min/max pressure settings on your APAP, you need to include the Pressure graph as well as the Flow Rate. This allows you to define a millisecond delay between vertical scrolling and horizontal panning. [Full Text]. 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. Source code for SleepyHead is found in this Sourcecode folder. In general: 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. The maximal pressure (max P) is typically set in the 20-25 cm water range as higher pressures are not well tolerated. If your leaks are frequently in Official Large Leak territory, you need to spend the time needed to figure out what's causing the leaks.
