I really don't understand which number is AHI and what it all means. Dr wants me to go for a second test and use a cpap. I have a problem with panic attacks and barely got through the first test. Please explain what results mean


Unfamiliar, I too suffered from Panic/Anxiety Attacks when I had my study and titration (about 3 months apart due to surgery). Once they got the PAP going, other then them coming in to change and adjust the mask, I did nothing but sleep. No anxiety, no panic, just sleep. And some pretty darn good sleep I might add.

I don't mean to sound condescending or as if I am making light of your panic issues, but trust me - I will all be worth it! My Septopplasty and sleep studies are some of the best decisions I have ever made.

Keep us posted.

I had a study done about 18 months ago and my AHI was 6. They wouldn't diagnose me. Repeat test in January was also just 6, however when they looked at my symptoms, they decided to go ahead and diagnose me and prescribe CPAP. My AHI has been between 0.3 and 1.8, averaging 0.8 for the two weeks I've been using CPAP. At even 1.8, I was dragging the next day.

I'm new to this as well, but my pressure was set ast 20/15 .......I don't know a lot of the terminology associated with the cpap, so I have quite a bit to learn. A glossary of apnea treatment terms would be helpful......wouldn't really change anything, other than understanding the condition that has been kicking my but for years now. 8)

Hey, terms and numbers, check out the sticky at the top of the forum. Early posts have a lot of definitions. http://www.cpaptalk.com/viewtopic/t35702/Where-A-CPAP-Newbie-Should-Start.html

Never got to REM during Sleep study (barely ever got to stage 3, either). They said 63 was what they counted, but thought the 'real' number was probably twice that. The expected my AHI would be much, much worse in REM. I was lucky that my insurance agreed to treat with the data they had because of the severity. Tech with 25 years experience said I was the most apnic patient she'd ever tested.

Edit: Remember, just as Georgio points out later in this thread, that AHI is the number of events per hour, not the total number of events for the night.

As I understand my number was different for 'normal' sleep and 'REM' sleep, so which number do you want?

AHI for the night, total sleep time.

I don't think the mean is a good measure of central tendency in the presence of outliers... In other words, 4 in NREM (notwithstanding continuous FLs) and 58 in REM ==> overall RDI of 15.7, which neither represents my NREM or my REM very well!

During the first study, there was an observation period of 4.5 hours during which I got 75 minutes of no REM sleep (24% sleep efficiency). I was having a respiratory disturbance index of 76 events per hour and apnea/hyponea index of 67.7 events per hour. 59 of the 84 events during actual sleep were central events and persisted between 7cm (51 CA/hr) and 10cm (68 CA/hr) of CPAP. Lowest oxygen saturation during that first study was 81%.

My AHI is 3-4 now.

My first study I was told moderate with 27 AHIs when on my side or stomach. They also said my back sleeping was severe but did not tell me the number. Funny thing is I don't recall sleeping on my back as I tried but couldn't settle that way.

I am going back on Saturday night to get my flow rate determined etc. I will ask what was the number for supine sleep.

I once was lost in apnea; but now I'm found--breathing easily all night long.

35ish, but the ratio was something like 4-to-1 hypopneas to apneas.
