AHI on Remstar 60 auto CPAP

I have using a new CPAP machine with an AHI reading for the first time the past two nights. A Remstar 60 auto as noted above. The readings have been 2.1 and 2.2. In a test this would mean the number of events per hour. Is it the same on the machine or is it 2.2 for the whole night? I am guessing per hour, but what do I know.

TIA

the ahi is a hourly average.

if you sleep 30 minutes and have 2 events, you'll have an AHI of 4.

if you sleep 4 hours and have 2 events, you'll have an ahi of 2. sleep 8 hours with 2 and have a .5 etc.

An AHI of <5 is considered treated, but most people using CPAP get less than that. 5 per hour is still 35 events over 7 hours.

AHI numbers displayed on the LCD screen reflect average per hour.

If you are new to CPAP therapy there are some helpful things to do:

1. Get a copy of your sleep study and your sleep titration study. They have interesting information that will help in understanding your own therapy

2. Get a copy of your prescription for your own records. It will be necessary if you choose to change DME's or order online

3. Post your equipment. There is a link on how to do this in my signature block below. Please select TEXT as a display choice as many CPAP machines and masks appear similar but are significantly different

4. If you need to post images of your reports, there is a link in my signature block on how to post using PhotoBucket.com

5. While the LCD display is somewhat useful, it is better to use one of the reporting software programs to get detailed information on your therapy. The two available for Respironics machines are: Encore (Basic or Pro) and SleepyHead.

it could also be 35 in 30 minutes and nothing the other 6.5 hours...

Thanks for the quick replies folks, much appreciated.
