What is CPAP?

CPAP, or continuous positive airway pressure, is a treatment that uses soft air pressure to keep your airways open while you sleep. CPAP is used for people who have lungful of air problems, such as sleep apnea.

This treatment is done using a CPAP device. CPAP device have three main parts:

A mask or other machine that fits over your nose or your nose and mouth. Straps keep the cover in place while you're wearing it.

A tube that connects the mask to the machine's glide.

A motor that puff air into the tube.

Some CPAP mechanism have other features as well, such as heated humidifiers. CPAP machines are comfortable, lightweight, and fairly quiet. The sound that they make is soft and rhythmic.


CPAP is the most effectual treatment for obstructive sleep apnea. Sleep apnea is a ordinary disorder in which you have pause in breathing or shallow breaths while you sleep. When this happens, not sufficient air reaches your lungs.
In obtrusive sleep apnea, your airways crumple or are blocked during sleep. The stumbling block may cause shallow breathing or breathing pauses. When you try to breathe, any air that squeeze past the stumbling block can cause loud snoring. Your snoring may wake other people in the residence.

The mild pressure from CPAP can prevent your airway from collapsing or becoming blocked.

If your doctor prescribes CPAP, you will work with someone from a home tools provider to select a CPAP machine.

Your doctor will work with you to make sure the settings that he or she prescribe for your CPAP machine are correct. He or she may suggest an overnight sleep study to find the correct settings for you. Your doctor will want to make sure the air pressure from the device is just enough to keep your airways open while you sleep.

There are many different types of CPAP machines and masks. Be sure to tell your doctor if you're not happy with the type you're having. He or she may suggest switching to a different type that may work better for you.
