Aura and Autopap

Paul B · Post by **Paul B** » Wed Mar 23, 2005 6:23 pm

I just received my Aura and will try it out tonight with my Resmed Spirit. Does anyone know why in the instruction booklet they say it can be used with a BiPAP or CPAP but not with an Autopap? Just curious what the reasoning might be.

Paul,

Read back a few threads and look at the ones with aura in the subject. There has been lots of discussion on the topic. The aura/spirit combination has been used by others with no problems, so you should be OK. Good question though.

Hi wader,

I did see those messages, but I'm curious why Aeiomed says not to use the Aura with an Autopap, but it's okay to use with a BiPAP or CPAP. I'm just trying to understand what the rationale is.

Paul, I think it has to do with the possibility - not certainty - that an autopap might not be able to detect events properly (or might think it is detecting something that's really not there) when the air flow characteristics change going through a narrow diameter hose (the narrow connector tube on some masks), or through other narrow tubes in some nasal pillows interfaces.

I take it as a caution - to be looked at by each individual. Things looked fine for me, AHI-wise, using narrow diameter connector hose masks with any autopap I've tried. Probably most people can mix and match with no trouble. I suppose the companies' cautionary "not recommended" statement is there for "just in case" - to cover themselves for the few patients whose autopaps might misread what's happening with their particular breathing and that particular change in airflow...just my guess, and I'm no doctor!

Thanks for the hypothesis, RG; you could be very right. I'm just really curious about it and it's got me stumped so I'll give them a call tomorrow and see if I can get an answer. I'll post it here when I find out.

Paul,

The only auto machine that does not caution against using a narrow tube interface is the Puritan Bennett 420E. Not coincindentaly their premier interface is the narrow tube Puritan Bennett Breeze.
