A-PAP pressure enough?

Post by myapapismadhot » Fri Jul 11, 2008 7:17 pm

Is there a way that I can tell if my A-PAP is set to enough pressure? Right now it's set to go between 5 and 10. I didn't go back for the second sleep test as I haven't really had the time. The 90% pressure reading is 7.8. My APN-HYP ratio is just under 5. Can anyone tell me if I should have this changed? THanks.

5 cm is considered too low for many, I couldn't even be comfortable on 10, That's why it's important to have the software and reader, so you can see what you need. most people with APAP's do better using a 3 CM spread on pressures, some do better on CPAP. I currently am using APAP at 15 CM only. The software and the way I feel tell me this is working best for me. Jim

I agree with Jim: Getting the software is worth it.

I don't agree whith his ephasis on higher pressures. Its true that the majority of people need higher pressure than 5, but some don't. For those that need lower pressures, higher pressure will not do the job. Everyone has to find out what is just right for them.

With a 90% reading of 7.8 your machine indicates that you belong to those who need lower pressures. That reading means you spend only 10% of the night at pressures higher than 7.8. Without sofware, you don't know your max. (But that's OK).

At an Apnea Hypopnea Index of just under 5 I would look for improvements. In my case, moving up the minimum pressure gradually (I can only do decimal increments on my machine) and tracking my data on a spreadsheet showed a distinct improvement when I move from anything below 6 min. to a min. of 6 - so that's where I am: min = 6.

Pay attention to how you feel: the quality of your sleep and the quality of your days, since giving those a good quality is the aim of this therapy.

AHI of 5 is not bad.

If you feel like you are starving for air, bump the Minimum pressure up to 6.0 or 6.5, make sure you can still fall asleep with it.
