pulmonary hypertension and flying

Patients with pulmonary arterial hypertension (PAH) may encounter specific risks during air travel. The reduced air pressure inside the airplane cabin can lead to decreased oxygen levels in the blood, potentially worsening PAH symptoms. Prolonged immobility can also heighten the risk of deep vein thrombosis (DVT) in the lower limbs, which poses a significant danger for PAH patients, as clots could dislodge and travel to the lungs, leading to severe health complications.

Prior to flying, individuals with PAH should consult a physician for a thorough evaluation. Doctors may recommend supplemental oxygen use during flights to ensure adequate oxygen saturation levels in the blood. Patients are also advised to opt for aisle seats to facilitate regular movement and reduce the risks associated with extended periods of sitting. Staying hydrated and engaging in light leg exercises during the flight can help prevent the development of DVT.

Thus, individuals with PAH should exercise caution when planning air travel and adopt appropriate preventative measures under medical supervision. Adhering to a physician's advice and maintaining good blood circulation during the flight can mitigate the potential risks associated with air travel.
