CPAP: The Disadvantages

CPAP Machine Disadvantages

First of all, what is a CPAP machine?

CPAP stands for Continuous Positive Airway Pressure (CPAP). It’s a machine that consists of a device that blows compressed air via tubes and a mask into your airway when you sleep. This air keeps your airway open, minimising snoring and sleep apnoea.

The disadvantages of a CPAP machine:

Cumbersome and obtrusive device

The purpose of the CPAP machine is to help you sleep better, however, the cumbersome design doesn’t necessarily lend itself to comfort. Added to this, you need to wear a mask all night, which may rule out some of your favourite sleeping positions.

Hard to get used to or tolerate

The sensation of having positive airflow blowing through nasal prongs and a mask all night is impossible for some people to tolerate.


CPAP machines range in price from $1000 to several thousands of dollars. However, given that many people can’t tolerate the CPAP machine, it ends up being a waste of money especially when that money can be better invested in an effective alternative.

Unsettling side effects

CPAP machines can have the following side effects: nightmares, nasal discomfort (including congestion, dryness, sneezing and runny nose), sore throat, irritated eyes, skin irritation and abdominal bloating.

Inconsistent relief

A lot of people who use a CPAP machine actually remove the mask throughout the night to get more comfortable. If the mask isn’t worn, then snoring and sleep apnoea will return for the night.


The CPAP machine is plugged into a power point and makes a noise throughout the night. While the noise is not overly loud, it is still audible, which can be frustrating for your bed partner.

Increase in electricity bills

The CPAP machine requires electricity to run, all night, every night, so expect an increase in your electricity bills.

Can interfere with sexual intimacy

Even though the CPAP machine only requires use while sleeping, having the device in the room can psychologically interfere with sexual intimacy.

A much better alternative to the CPAP machine is the Mandibular Advancement Splint.
