My tube fills up with water at night. What can I do?

Here's what you can do to reduce the build up of water in the tube.

You might have heard the term 'rainout' in reference to humidification. Basically rainout is condensation building up in the tube. If you have rainout, you might hear a gurgling sound in your tubing when you breathe on therapy.

Here's what you can do to reduce rainout:

  • Use ResMed's Climate Control humidification solution, which is designed to provide enough humidification to help you breathe comfortably, while keeping rainout at a minimum. Make sure you're using a ClimateLine™ heated tube.
  • If you're still experiencing rainout, try turning the humidity level down a little.
  • Rainout can happen if your bedroom gets too cold at night, so try to keep your room warmer overnight.
  • If you’re not using ClimateLine, to keep your tubing (and the air travelling inside it) warmer during the night, you can use a tubing wrap.
