What is the range of cm in an APAP?

[pwpyle]

I currently use a 6 year old CPAP, I will be purchasing an IntelliPAP APAP Machine and I was just wondering how far the APAP can go (up or down) in cm's. If my pressure is 9...and it automatically adjusts for apnea episodes, it there a set range that it will follow and how wide is that range.

Thanks,

As far as I know all APAPs are 4-20. But 4 is usually too low a starting point, and you may not need 20, so it seems to help to narrow your range.

APAP'S have a pressure range of 4cm to 20 cm, but to be effective a 3 or 4 cm treatment range is better as it allows for the machine to better respond to a event. Too high a spread and it won't be able to get to the needed pressure in time. Jim

BPAP's have a higher pressure range some go to 30 cm.

A number here have found that setting the minimum up to within one or two centimeters of what they need for preventing apneas gives them the best sleep, unless they have comfort considerations (such as air-swallowing problems) that would suggest otherwise in their case. Some even set the minimum up to where all apneas are prevented and the machine only raises pressure in the prevention of hypopneas in their case. A little experimentation on your part can determine what minimum serves YOU best.

Lowering the maximum is generally only necessary if a machine's algorithm tends to run away with you, increasing pressure for no valid reason based on the way it evaluates your individual breathing.

Software can be very valuable for determining such matters.
