Using ice for cold air?

[Jljbtm]

I've read here about using ice in the humidifier but it doesn't last all night. My reason for wanting cold air is because cold air is more dense and it helps my blood oxygen level during sleep. On cool nights I'll place my cpap machine in the window to draw in cool air, but what about hot and humid nights?

You read on here, where?


While it's true that cold air is more dense than hot air (and carries more O2) by the time this 'cool air' reaches your lungs, it's no longer cool and any additional O2 is no longer additional.

You can do as you like of course but, in my opinion, there's no benefits to what you're doing.

Which type of blood-ox issues are you having?

This is true for ice in a CPAP humidifier. For activities in cold weather, the lungs do get additional O2 as compared to those same activities in warmer weather.

I can identify with the low O2 levels overnight- our air is actually heated, has anyone tried disconnecting the heater or had a heater fail? Not sure about ice in the tank but it would be nice to O2 enrich the air going in. Also perhaps feeding pressurized O2 into the mix- without a signoff? I am close to a reagonal airport and do work for several pilots, who often use O2 for high level flights.

Please share your actual NUMBERS.
Preferably with your DOCTOR.
If there is an actual problem, it is unlikely putting ice anywhere will help.
I remember someone trying ice, but it was for COMFORT, as I recall.
