AHI versus Events Per Hour?
Using Airsense 10 - I had always assumed the "Events Per Hour" was the same as average AHI - What is Events Per Hour? Last night, the EPH were 2.5 and the AHI said 6.5.

RE: AHI versus Events Per Hour?
AHI is the EPH for all types of apneas(CA +OA) + hypopneas

RE: AHI versus Events Per Hour?
okay I give up where are you seeing EPH. I have scanned the manual, done a search on the web, and liked at sleepyhead-none of these places knows anything about EPH that I can find.

RE: AHI versus Events Per Hour?
Well, I found it; but cannot find a definition. I did find that it Events per Hour of Use.
I would just be guessing as to why AHI > EPH. It is a darn good question and deserves to be reconciled. Bump! Admin Note:

bluemom51,
Found this description. Does this make any sense? AHI = AI + HI = number of events per hour (obstructive + central + unknown + hypopnea) Total AI = number of events per hour (obstructive + central + unknown) AHI - AI = Hypopnea Index = number of hypopnea per hours

He's one of the board's best! yep - changed the time period to daily and EPH aligned with AHI and wonder of wonders, i achieved a AHI of 2.3 last night - it's a miracle - i had upped my lower pressure per someone's advice and i hesitantly took 1/2 the trazadone pill my doc had given me to try and..........(sound the chimes and bells).......my lowest AHI ever. i guess setting the pressure to a tighter range and raising the bottom pressure along with something to calm my intense tossing and turning really worked. i am (per the British) gobsmacked!! so in summary, the events per hour is just showing you the AHI at the top of the little screen so you don't have to turn the dial down, and yes, as it turns out, i did deserve the smiley faces. yeah!!! |
