Why am I spitting out water during the night?

Postby sskat » Sun Feb 27, 2011 9:26 am

Hi, I was diagnosed with moderate sleep apenea and have been using a CPAP machine for nearly two months now. I use nasal pillows and have had relatively few problems with leakage, and I feel as though I've adjusted fairly well to using the machine. There's one strange thing that occurs occasionally at night, however ... I wake briefly and water (or saliva?)comes out of my mouth. It's happened 4 or 5 times since I began using the CPAP. Has anyone experienced this or know what is causing it?

Hi sskat!

The only thing I can think of we in the hose head crowd call "rain out". Simply, water vapor condenses on the inside of the hose - forms a bit of a puddle - then a change in position or similar event causes the water to run into the mask. It may be that the water briefly wakes you up as it hits you or becomes a problem with your breathing.

Some people have made cloth covers for their hose - they do make heated hoses to get rid of the problem. If you do not mind a raise in temperature at night that might also help (tends to reduce condensation).

May we sleep soundly through the night!

Make sure the machine is lower than the level of the mattress (although should not be on the floor, especially if you have carpet). Hang the hose over the head of the bed or put a hook on the wall above your head when you are sleeping. The idea is to have as much of the hose as possible draining back into the humidifier rather than into your mask/nose.
