Water in hose?

Bytor · Post by **Bytor** » Tue Nov 20, 2007 12:34 pm

I have two questions..:

(1) Ever since using the Nasal Aire II, about 4 to 5 hours using it, water starts accumulating in the tube going out of my 'M Series Auto CPAP with A-Flex with heated humidifier'. I mean like, condensed water, not water vapor. The only problem this ends up causing for me is that it makes a popping sound when, presumably, it shoots out of the exhaust on my mask. When this happens, I disconnect my mask from the hose, aim the hose into a cup or something, and turn the machine back on, about about 3 ounces of liquid water comes out. I have my humidifier set the smallest setting. How can I fix this?

(2) I'm looking at my reports in Encore Viewer Pro. I understand most of it but what is a "Flow Limitation Event"?

Thanks so much, you guys rock!

Two sources of water in the tubing & mask; one is of course the humidifier-keep the hose in a position that drains it back to the humidifier-keep the hose insulated-room warmer. Maybe you don't need to use the heat aspect of the humidifer at all-sometimes I just run mine in passover mode-no heat. Keep experimenting.
The other source is the condensation from exhaled air.
I like a cold room to sleep in-my tubing is well insulated and doesn't give me much trouble. The exhaled moisture does get bothersome when it is really cold-one of the things I'm going to try is a modified ski mask to keep the nasal cushion a little warmer.

The way I think of flow limitation-when the airway starts to "collapse"-think snoring comes next a lot of times-then hypopnea-then obstruction. OK now experts--did I oversimplify/or am I totally off base that as a progression to obstruction?

I have the respironics built-in humidifier with the m-series... and I don't believe there is a way to use it in passover mode? or do I simply set the knob to the "off" position, and the air is still moisturized?

I have a RemStar with heated humidifier and just don't push the button that turns the heat on. Oh the things I forget-I haven't reset the heater for over a year-but I don't think it sets to 0-so just don't turn it on-the air still flows through the humidifier-and I still add water to the chamber.
