Air racing out of mask exhalation holes.

I am having a horrible time sleeping with the noise made by air blowing out of the mask. It has awakened my spouse because he was getting cold by the air blowing on him. Orginally, I had a nasal mask and thought maybe it needed to be replaced when this happened. I now have a face mask and I sound like Darth Vador with every breath and the air flow seems even louder.

I was excited to get my cpap because I was assured the machine was "silent". Well, the machine is silent but the rushing air is preventing me from fall asleep and/or is waking me (and my spouse) up. Is there a way to stop this?

I don't have a complete answer to your question, but I'd love to hear one. I have nasal pillows, and have found that adjusting the fit modifies the sound. Also that I need to put the mask on BEFORE turning on the machine.

Hi Trebor,

How the air comes out of the exhalation port depends a bit on the individual mask. Most Fisher & Paykel nasal masks have a diffuser over the exhalation port which make it virtually silent. This would be the HC405, HC406, HC407, Eson and Eson 2 if you want to look them up. Their full face mask does not. The quietest, least blowy full face masks are probably the ResMed Quatto Air, AirFit F10 and AirFit F20. The don't direct the air straight out but have a circular pattern that is more diffuse. They may help you.

Most masks are not that noisy though. Is it possible that a leak is causing the noise? When it is being noise, press around the outside of your mask. If the air gets quieter when you press in a particular spot then you probably have a leak there. The mask will also be noisy if not correctly assembled. Some models have pieces which can be almost-but-not-quite clicked together which will result in a noisy leak. Lastly, if you hear a lot of noise as you breathe in and out, this normally only happens when you are awake and breathing deeply. As you fall asleep and your breathing becomes more relaxed this noise usually disappears.

Which mask do you have?

I have the ResMed AirFit F20. I have taken it apart and reassembled several times but find nothing defective. My headgear was set by my provider so I haven't changed that. I wash the pillow daily making sure to be gentle so not to damage anything. I guess I'm just overly sensitive to nighttime noises and with time will become accustomed to it.

Here's to sleeping better,

I swear this thing is trying to send me flying around the room! I've had to turn off the machine and restart in order to lessen the air noise so I can sleep. I bet I could blow dry my hair with the air coming out of my mask.

Could this be a case of too much pressure?

If you had a sleep study to ascertain your pressure then it should be correct. However, some settings on your machine may have an effect here. What are your ramp settings like? Also, do you have an auto CPAP? If so, there will often be more air when you wake up because the machine has turned itself up to treat your OSA. Stopping it and starting it again is the right move in that case. Mask leak will also cause your machine to blow more - this is called leak compensation.

My wife complains about the cold air, too. I usually sleep on my side facing her. My solution it to pull the sheet and blanket up over my head. I have all the air I need coming in through the hose and it keeps her from getting that draft. Plus, she can stay up and read longer because I'm in the dark, too.
