My wife had a sleep study in June which came up with an AHI of 32.2/H with no central apneas. The longest OA was 72 seconds.
She was immediately prescribed a CPAP/APAP machine -a Resmed 10 autoset set to 5 -15 cm H2O in APAP mode.
This brought her AHI down to 7/H, but kept waking her up, due to the air pressure opening her lips with a resulting (noisy) gale.
Since then, the visiting technician has brought the pressure down to 4 - 6 in CPAP mode.
She now sleeps better, although her lips are still forced open from time to time (even when taped up) and her AHI varies between 1 and 3.5 / H. Which sounds good, but she has a lot of small apneas (<10 seconds) which aren't logged and then, typically, a packet of 20 -30 second apneas usually between 4 and 6 o'clock in the morning.
I've read some very interesting posts on the forum and have been trying to understand the results on ResScan and Oscar but some nights I can't make head or tail of them . . .
Could someone offer advice on how to proceed, please ?
PS she'll be 74 this year.
Thanks in advance.
