Sir,
My mother is using Philips Respironics Bipap for past one year. But from past fortnight her AHI is increasing. The apnea alarm buzz even at 30 setting after regular interval.
Please suggest as per report attached if we should change setting or any information which would be helpful.
My mother is 60 years, weight around 130 kgs. We are located in India.

Thanking you

Devesh

Overall it looks like she's doing fairly well. I suspect a mouth leak or mask leak. Quickest fix is a soft cervical collar to wear at night. This will keep the jaw locked in place, prevent mouth leaking, and keep her from having a dry mouth when waking.

I've been to India a couple times and it wasn't exactly known for being cool at night, so this might not be the best option.

Hello,
Thanks for reply. I have already placed order for soft collar. My concern is Breath trigger alarm (it is below 50%) and ventilator alarm( continuous alarm but AHI lower then 5) . Please check the report and any suggestion will be of great help.

Thanks,
D. Gupta

In one of Jasons' videos he said you can use sleepyhead to determine how to adjust the pressure levels. I can't figure that out from the sleery head presentation of the data. Without cpap ahi 46 with cpap 17.8. Not bad but was hoping better.

Well, post a couple screenshots, as shown in my sig.

and, btw, 17.8 is *terrible*.

But, do start your own thread.

Image I hope this works. I was sent to the sleep lab because I have Afib. A couple times a week i would wake up gasping for air. I figured that is because my heart likes to stop and take a short rest. However, it seldom happens with cpap. The trade off, hard to sleep with cpap/bipap. Actually had one good night sleep this month AHI went under 3. Very unusual for me.

Well, your pressure is too low, and your PS may be too high.

If it were me, I'd switch to vauto mode
MinEPAP 10
MaxIPAP 25
PS 4

and see what it does the next night.

What is PS?

Post subject:  Re: AHI increasing

I set it for vauto and ps of 10. Is that correct?

PS is the difference in EPAP and IPAP.

EPAP =10 IPAP=15, that means a PS of 10.

so a bilevel pressure can be written 15/10, or epap 10, ps 5.

usually a fixed pressure bilevel has EPAP and IPAP settings, an auto machine usually has a minepap, maxipap and ps, settings, so you set the starting pressure and the ps, then it varies up and down as needed.

After setting my macine to Diamaunt suggestions. I had AHI 9.7 last night. It showed ahi 12. for 38 min of being awake. I'm not sure I believe Resmed software anymore. I get to meet with a sleep tech 7/24. S/he will probably upset that I changed settings, but tough. I don't give up so easily.
