I had the opportunity to try the Remstar pro C-flex and humidifier last night and was pretty amazed at the advances made over the last 8 years.
What really intrigues me is the ability to see (using the wonderful SleepyHead software and a clone of the SD card) each and every breath I took.
If the amplitude and duration of the "flow" chart corresponds directly to the depth and rate of my breathing then the events that this machine calls "hypopneas" aren't very scary. Also, the machine registered several hypopneas and an apnea before I was even asleep.
The machine told me I had five OAs during the night; none longer than 10 seconds and eleven hypopneas; none longer than 16 seconds.
This is just for one night of course.
Is there a guideline for these events in terms of their duration and the expected harmful effect?
The clinical definition for an apnea or hypopnea is obstructed or shallow breathing events greater than 10 seconds, and they are harmful in their cumulative effect of disturbing sleep and decreasing blood oxygen levels throughout the night.
5 OA + 11 HP over 7-8 hours suggests an AHI ~ 2, which qualifies as "treated" apnea but mine are typically < 1 with a pressure range of 7-12. Since it sounds like you have a relatively mild case, you might be able to achieve even fewer events by raising your pressure slightly.
