A CPAP is a bedside machine pushing gentle air pressure through a mask to hold your airway open - no drugs, no surgery.
NHLBI notes the fast wins: better sleep, less snoring, less daytime sleepiness within days, plus long-term heart and brain protection. Masks feel alien for a week or two; comfort fixes solve most of it - tell the clinic, do not suffer. Forever is the default while the cause persists, but major weight loss, positional treatment, oral appliances, or surgery change the picture for some - confirmed by a repeat sleep study. Benefits track with nightly hours on the mask.

Common questions
What is a CPAP and do I have to use it forever?
CPAP - continuous positive airway pressure - is a small bedside machine that delivers mild air pressure through a mask to keep your airway from collapsing while you sleep, per NHLBI: no drugs, no surgery, just pressurized air holding the passage open. The benefits arrive fast - NHLBI notes better sleep quality, reduced or eliminated snoring, and less daytime sleepiness often within days - plus long-term protection for heart and brain. The honest adjustment curve: masks feel alien for the first week or two, and comfort fixes - different mask styles, humidification, pressure ramping - solve most of it, so tell the clinic instead of suffering or quitting. As for forever: apnea is usually a structural condition, so nightly use is the default as long as the cause persists - but it is not a life sentence for everyone. Major weight loss can shrink or resolve apnea, positional apnea responds to side-sleeping, and oral appliances or surgery fit some cases - with a repeat sleep study to confirm any change. The nightly-use rule that matters: benefits track with hours on the mask, and most insurers and doctors look for at least 4 hours a night.
