Continuous positive airway pressure, better known as CPAP, is a common type of therapy for obstructive sleep apnea (OSA). It’s also used to treat COPD and overlap syndrome, a term used when a person has OSA and COPD, concurrently.
How Does the CPAP Machine Deliver Air and Oxygen?
The CPAP machine
comes equipped with either a mask that covers your nose and mouth or a mask that covers your nose, only. The mask is fastened to a long, plastic hose that’s attached to a machine. The machine has a motor that blows air into the hose.
What Does a CPAP Machine Do?
CPAP uses mild air pressure to keep the breathing passages open during sleep, a time when many people with OSA and/or COPD experience a drop in oxygen. CPAP can be used with or without supplemental oxygen.
When is CPAP Indicated?

is usually the best treatment for OSA
, a condition that results in episodes of shallow breathing and/or “apnea” (cessation of breathing) during sleep.1
In addition, people with stable COPD
who have normal oxygen levels during the day but whose oxygen saturation drops during sleep may also benefit from CPAP. Finally, in severe COPD,
CPAP can be thought of as the middle man between standard oxygen therapy and an artificial breathing machine, often delaying the need for intubation and mechanical ventilation.
Benefits of CPAP in OSA
Symptoms of OSA and overlap syndrome include loud snoring, interrupted sleep patterns and excessive daytime sleepiness. Many people who use CPAP regularly feel better after they begin treatment, reporting an increase in mental alertness and improved job performance during the day and better sleep with less snoring at night.
Benefits of CPAP in COPD
Not only does CPAP often delay the need for intubation and mechanical ventilation, it can also help people with overlap syndrome live longer. According to a study published in the Journal of Clinical Sleep Medicine, people with OSA and COPD who used CPAP more than two hours a night lived longer than those who used CPAP less. Researchers also found that CPAP was especially beneficial in COPD patients already using long-term oxygen therapy (LTOT).
COPD can lead to other medical conditions as well, including chronic hypercapnia, a condition that occurs when elevated levels of carbon dioxide (CO2) are found in the blood. Left untreated, hypercapnia can be fatal. According to a report issued in American Family Physician, CPAP can help COPD patients with hypercapnia when correcting the underlying cause does not solve the problem.
