In-flight continuous positive airway pressure

Continuous positive airway pressure (CPAP) may be required by some patients with severe obstructive sleep apnoea on long-haul flights. Consider the possibility of worsening hypoxaemia when asleep.

If CPAP is necessary, the airline should be consulted before booking; airlines may have a list of approved CPAP devices allowable in-flight. Information on carrying CPAP machines on a flight can be found on the Qantas website. A doctor’s letter outlining the diagnosis and necessary equipment may be needed. The letter should state that the CPAP machine should travel in the cabin as extra hand luggage. Dry cell battery–powered CPAP can be used during the flight but must be switched off before take-off and landing.

During the flight, patients with obstructive sleep apnoea should avoid factors that worsen their apnoea, such as alcohol or sedatives.
