5 Common Causes of a Whistling Sleep Apnea Machine

5 Common Causes of a Whistling Sleep Apnea Machine

You have to acclimate to more than just how your new CPAP machine feels on your face. The sounds of the machine may also frustrate you for the first few nights. But once you get accustomed to the noises, it’s smooth sailing—until you notice a funny whistling sound. You can identify the source of the noise with these five common causes of a whistling sleep apnea machine.

Ill-Fitting Mask

A properly fitting CPAP mask should provide a nice fit and a tight seal that prevents air from escaping. Hearing CPAP sounds when breathing may indicate a leak. Wearing a too-large mask might allow pressurized air to escape, generating the whistling sound. Try altering your mask using the headgear straps so it sits securely on your face. If that doesn’t work, you might need to explore a different cushion.

A fractured frame, torn cushion, or blocked diffuser might generate CPAP mask noise. If you realize that the cushion is damaged, replace it right away. Tweaking your equipment using tape or glue might cause more harm and potentially violate your warranty.

Bad Connections

We’ve all had that moment of panic when we plug something in, and it doesn’t work. Our instant thought is impending doom and what it will cost to purchase a new computer, phone, or lamp. But then you find out it’s the cord, and your expensive equipment is fine.

The same situation can happen with your CPAP and the hose connection. Whistling occurs when air escapes from an improper connection. So, it could be as simple as unfastening and tightening it again.

Dirty Filter

Regularly changing filters will guarantee that your CPAP treatment is successful and can help extend the life of your CPAP equipment and reduce unsettling sounds. You should swap yours every two to four weeks. Cleaning them consistently also improves their effectiveness.

Cracked Humidifier

A humidifier is a key component for any sleep apnea device because it ensures the airflow remains heated. When it starts to deteriorate, the water chamber could begin to whistle. Inspect the humidifier to confirm there aren’t any cracks, or you’ll have to replace it. It’s a safe assumption you’ll need a new humidifier every three to five years.

Temporary Fix Before Replacing the Machine

If you’ve verified everything is working, and it still sounds like Snow White’s seven dwarfs are off to work, consider playing some white noise until you can purchase a new machine. There are several options, so no shortage of sounds could soothe you. If the white noise drowns out the whistling that was driving you mad, it’s a winner.
