How can individuals with respiratory conditions best prepare for air travel?

The air on planes has lower oxygen levels, which can be problematic for individuals with chronic obstructive pulmonary disease or asthma as it can lead to reduced oxygen in their blood. Therefore, it is important for such individuals to check their health before traveling by airplane.

Dr. Dang Thanh Do from the Department of Respiratory Medicine at Tam Anh General Hospital in Hanoi warns that the dry air inside airplane cabins can irritate the respiratory tracts of patients with sensitive airways, increasing the risk of acute exacerbations of asthma and chronic obstructive pulmonary disease. Additionally, the low atmospheric pressure in the cabin can cause complications such as burst air bubbles in the lungs, leading to pneumothorax, as well as venous thromboembolism and pulmonary embolism, especially during long flights.

Patients with moderate to severe chronic obstructive pulmonary disease, severe asthma, congenital lung cysts, pneumothorax, hypoxemia, or increased carbonic anhydride levels should carefully assess their health status before flying. Individuals recently discharged from the hospital within 6 weeks for acute respiratory failure, with a history of venous thromboembolism, receiving oxygen support or artificial ventilation, or being treated for otitis media, should also undergo a health evaluation before air travel.

Those with respiratory diseases that can be contagious to others, such as progressive tuberculosis or viral bronchitis, should avoid flying until fully recovered. Patients with chronic lung diseases or difficulty breathing with physical exertion should check their oxygen saturation levels before flying. Additionally, individuals requiring supplemental oxygen during flights can contact airlines to inquire about oxygen supply options, which may come with additional fees based on regulations.

It is recommended for patients with respiratory conditions to quit smoking, as cigarette smoke can further impact oxygen levels in the blood. Preparation of preventive medications for underlying diseases and familiarity with airline regulations regarding carrying medications is crucial before flying. Consulting a healthcare provider if there are concerns about flying due to an existing condition is advisable, and taking necessary precautions can help patients travel safely by plane.
