어떤 CPAP 기기를 선택해야 할까요?

For most newly diagnosed adults with uncomplicated obstructive sleep apnea, an auto-adjusting (APAP) device is the most commonly prescribed first-line therapy. APAP adjusts pressure breath-by-breath rather than holding a single fixed pressure, which most patients find more comfortable. The actual prescription depends on your sleep study results and your physician's clinical judgment.

Yes. CPAP, APAP, and BiPAP are FDA-classified Class II medical devices and require a prescription from a licensed physician. The prescription specifies pressure setting, device type, and accessories. Reputable suppliers will not sell a PAP device without one. The most efficient path to a prescription is a home sleep test interpreted by a board-certified sleep physician.

CPAP delivers one continuous fixed pressure. APAP automatically adjusts pressure breath-by-breath within a prescribed range. BiPAP delivers two pressures — higher on inhale, lower on exhale — and is used for patients who cannot tolerate high single-pressure CPAP, who need pressures over 15 cm H2O, or who have complex conditions like central sleep apnea or COPD overlap.

Out-of-pocket cost varies widely depending on insurance, device type, and supplier. Most insurance plans cover PAP devices and ongoing supplies when ordered by a sleep physician after a positive sleep test. Medicare covers PAP device rental for the first three months and then purchase, conditional on documented adherence of at least four hours per night on at least 70% of nights during the first 90 days.

A well-maintained PAP device typically lasts five to seven years. Insurance plans generally cover replacement of the main device every five years. Consumable supplies are replaced more frequently: mask cushions every one to three months, full masks every three to six months, tubing every three months, and disposable filters monthly. Most insurance plans cover supplies on this replacement schedule.

Yes. PAP devices are TSA- and FAA-approved as carry-on medical devices and do not count against your carry-on baggage limit. Some patients add a small dedicated travel device for frequent trips — these are usually a cash purchase since insurance typically covers only one device per replacement cycle. When traveling, bring a copy of your prescription, a bottle of distilled water for the humidifier, and a universal power adapter for international destinations.
