How to prevent CPAP Rainout?
There are more solutions to the CPAP rainout problem. Most of them are simple. Some require investment, but some just need one or two things that you probably have in your home. Let’s see how to prevent CPAP rainout…
1. Use CPAP heated hose
This one is the simplest and most effective solution. Buying CPAP heated hose might be an investment, but it is a sure way to solve the problem! If the air inside the hose remains warm, it doesn’t condense into droplets. A heated hose usually has a copper wire wrapped around it (inside the hose wall) which is heated and thus helps reduce CPAP rainout by keeping the temperature of the hose and air in the hose consistent.
2. Wrap hose to keep it warm
CPAP accessories industry offers many solutions for a small amount of money. One of these solutions is a hose wrapper or hose jacket. This is a specially created hose wrap that helps to insulate the hose and keep it warm. This is especially effective and recommended in cold rooms. If you don’t have hose wrap, you can try wrapping it with whatever clothes you have, even put it under the blanket if possible.
3. Adjust your humidifier settings
Some heated humidifiers have a temperature setting option. Usually, humidifiers will try to heat the air to around 80°F, but you might try to increase or decrease this. However, this method should be done with consultation with your CPAP doctor. Setting humidification to be too hot can make the air lose some of its humidity and be less effective.
4. Automated Adjustment CPAP Machines
With the advancement of technology and the development of the CPAP industry, everything that can be automated is being automated. Leading CPAP industry companies are competing which one will make the best CPAP solution, reduce discomforts, and improve the CPAP experience. So, for example, the S9 and Air Solutions CPAP machines from ResMed feature automated adjustments designed to maintain humidity levels. This climate control feature monitors the temperature of the air in the mask and how it is affected by ambient temperature. If needed, the system will simultaneously adjust the humidifier and hose heating levels, to provide an optimal temperature and thus prevent CPAP rainout.
5. Adjust the room temperature
If this is an option, you can try to resolve the issue by simply adjusting the room temperature. If your room is cold and that is what's causing the rainout, you can try and set the room temperature to be warmer. This is a quick and simple fix, but it comes with the price of your sleeping comfort if you are used to sleeping in a colder room.
6. Move CPAP machine
Again, one simple and quick solution that doesn't require any investment or has any influence on your sleep comfort… By moving your CPAP machine to the lower level than your bed (your mask), you will apply simple physics and with the help of gravity, you will get rid of the rainout! Or at least you will get rid of the rainout in your mask. Any water droplets that form the condensation will flow back into the humidifier instead of flowing to your mask.
