Definition
Continuous positive airway pressure (CPAP) is pressured air delivered into the airway by a machine.
Reasons for the Use of CPAP
CPAP is used
to keep the airway open. This lets air move in and out of the lungs more easily. It is used most often to manage
obstructive sleep apnea
(OSA). OSA is a series of pauses in breathing during sleep. It is caused by relaxed throat muscles that press into airway while you sleep. which can lead to:
CPAP may also be used in preterm infants. It supports their lungs until they develop.
Possible Complications
CPAP is considered safe. Some problems that can happen are:
-
A feeling of
claustrophobia
or suffocation from wearing the face mask
- Rash or sores in the area of the face mask
-
Stuffy nose and
nosebleeds
-
Sore eyes,
conjunctivitis
- Sore or dry throat
- Headaches
- Belly bloating
- Chest muscle discomfort
What to Expect
Prior to Getting a CPAP Machine
Before prescribing a CPAP machine, the doctor may advise you to:
- Be in a sleep study
- See a doctor who specializes in OSA
- Quit smoking
- Lose weight
- Get more physical activity
Description of Machine Use
The CPAP machine has a pump and a face mask.
The pump sits off the bed. It has a tube that goes to the face mask. The face mask will be tightly secured to the head so that air will not leak out. The pump will force air through the airway. This will help keep the airway open. The face mask will need to be worn during sleep.
How Long Will It Take?
The machine will be used for as long as it is needed.
Will It Hurt?
Some have reported skin, eye, or nose irritation or chest muscle and belly discomfort. The doctor may advise ways to relieve any discomfort.
Average Hospital Stay
CPAP machines will be used at home.
Post-procedure Care
Stopping use of the CPAP can cause OSA problems to return.
