2009年11月19日 · Divide 400 by 420 =.95 x 60 = 57 AHI (Severe OSA) Two measurements of Sleep Disordered Breathing Apnea(SDB) Remember AHI is an Average. The AHI of 14.3 is an index -- an AVERAGE calculated for the entire night. It doesn't mean you stopped breathing literally 14.3 times each and every hour.

2011年8月24日 · satisfied with a 30 min nap instead of 2 or 3 hours. I don't conciously feel more awake, but I seem to be much more productive and I have taken an interest in completing tasks that have lay dormant for a couple years. So, is 2.1 AHI good enough or should I be tinkering to achieve better. Jerry _____

2019年9月13日 · The doctor said I didn't have sleep apnea and my airway narrowed slightly a couple of times throughout the night. Apparently my ahi was 2.5. How accurate is this number when done with an at home study? I know with sleepyhead there can be false flags. Could the same be true with my at home study or am I for sure waking up 2.5 times each hour?

2008年5月29日 · Your AHI is 2.9, but if your AI/apnea index is 2.0 and your HI/hypopnea index is .9, and you sleep 8 hours, that's 16 apneas per night, and your oxygen levels could be dropping too low. You would need an oximeter to measure this. If, on the other hand, if your your AI is .1 and your HI is 2.8, then that's a much different picture.

2011年6月10日 · 3.7 AHI is not low, but it is in the good zone... anything below 5. Most of us strive to reach 1 or 2 at most. Many are below 1. I average 1.5 but have had a reading as low as 0.3. A lot of this depends on the data, too. One can have a great AHI but the events shown in the data may be caused by leaks or centrals....and those things need to be ...

2014年8月1日 · The Events per hour ...2.5 is the AHI for last night. The other numbers are from the cumulative total screen and that means the 9.1 is the overall AHI over the period you have chosen to display the results. Elevated AHI long term (that 9.1) is probably secondary to a lot of initial awake breathing stuff getting flagged by mistake.

2013年1月28日 · I read elsewhere on the forum that was a known problem with the S9 Autoset, and the fix was to unplug it from the power supply, hit the power button to discharge any residual charge remaining in the capacitors, wait several hours, then plug it back in. I did so and it resumed scoring my events, which are usually 0.2 to 0.5 AHI.

2012年2月8日 · AHI = (2 events)/(29 minutes) = (2 events)/(29/60 hours) = (2 events)/(0.48 hours) = (2/0.48) events/hour = 4.16 = 4.2 when rounded to one decimal place. That's acceptable on a titration study---particularly if those 29 minutes contained some REM sleep or some supine sleep or (the gold prize) some supine REM sleep.

2011年9月22日 · It means that for 2 % of the night (time asleep) there was some Periodic Breathing. Defined in PR S1 clinical manual as "A persistent waning and waxing breathing pattern which repeats itself between 30 and 100 seconds. The nadir of the breathing pattern is characterized by at least 40 & reduction in air flow from an established baseline flow.

2021年7月9日 · So while their software reports show a nice low AHI at so and so pressure in real life (and in sleep studies with the Pes device) they end up needing more pressure than the machine will feel the need to deliver so people have to start out with higher minimums than it looks like that might "need" per what the machine is doing.
