Values are presented as number (percentage). ^aFor 180 patients with complete physiologic data during flight. ^bIf normoxemic, oxygen saturation of greater than 90% before flight. ^cVentilator interventions included switching to manual ventilation or beginning inhaled prostacyclin. ^dIncludes new administration of fluid bolus, beta blockers, or titration of vasopressors.
