No. It is not necessary and some people don’t use it at all or only use it during the winter when the air is very dry due to heating. The purpose of the humidifier is to moisten the incoming air so that it doesn’t dry the sinuses. If you breathe solely through your nose, your nasal passages naturally humidify the incoming air.
Condensation in your mask or tube, often referred to as “”rain-out”” and can vary from just a few water droplets to a significant collection of water in your tube.
Rain-out is caused by the difference in temperature between the warm moist air in the CPAP and the colder air in your bedroom.
To solve this problem, you can one of three things: make the room warmer, keep your tubing warmer, or turn down your humidifier.
To keep your tubing warmer, you can put it under the covers with you, or cover it with a tubing cover. Or, as an even better solution, you can upgrade your CPAP to use a heated tube. Many manufacturers offer a heated tube option or add-on, or you can use the Hybernite ‘stand alone’ system that works with any CPAP.
Most of these solutions will be better than turning down your humidifier if you have any tendency toward waking with a dry mouth.
A bloody nose during CPAP use is a common problem, especially in the beginning of CPAP therapy. If you have a heated humidifier, try adjusting the level of humidity to make sure you are getting maximum humidity without creating condensation in your tubing or CPAP Mask. You might also try using a nasal saline spray or a ‘neti pot’ before bedtime to moisten your nasal airway. To maximize humidity in your airway without causing ‘rainout’ in your tube, upgrade to a heated tube. Talk to your doctor if you continue to experience a bloody nose during CPAP use.
Making sure your machine is delivering an appropriate level of pressure is also important in keeping inflammation and congestion to a minimum. If you use an auto adjusting CPAP, and it’s settings are correct your pressure is automatically optimized. If you use a standard CPAP have your CPAP data analyzed and your pressure checked by a professional to at least once per year and also when you have pressure-related problems (such as an unresolved bloody nose during CPAP use).
