ABSTRACT
Patients should be evaluated prior to travel with measurement of arterial blood gases or oxygen
saturation. Patients with Pao2 less than 55 torr at sea level should have in-flight supplemental oxygen at 2
LPM by nasal cannula or 28% Ventimask. Patients with hypercapnia, CHF, or angina should have inflight supplemental oxygen if Pao2 ^
60 or oxygen saturation < 91% on room air at sea level. Patients already on supplemental oxygen may require an increase in flow rates during the flight
and will require their home care supplier to make arrangements for oxygen at their travel destination.
