Can someone fly with a collapsed lung?

In general, flying with a collapsed lung (pneumothorax) is not recommended and can be potentially dangerous. Here's why:

Cabin pressure: The air pressure inside an aircraft cabin is typically lower than the air pressure at sea level. This change in pressure can cause the collapsed lung to expand, which can be painful and may lead to further complications.

Hypoxia: A collapsed lung can interfere with the exchange of oxygen and carbon dioxide in the lungs, leading to hypoxia (low oxygen levels in the blood). This condition can be exacerbated at high altitudes, where the available oxygen is already lower.

Barotrauma: Rapid changes in cabin pressure during ascent or descent can cause barotrauma, which is damage to the body's tissues due to pressure differences. This can affect the lungs and worsen the collapse.

Pneumothorax tension: In some cases, a collapsed lung can lead to a condition called pneumothorax tension. This occurs when air accumulates in the pleural space (the area between the lung and the chest wall) and puts pressure on the lung, heart, and other organs. Pneumothorax tension is a medical emergency and requires immediate treatment.

Given these risks, most doctors advise against flying with a collapsed lung. If you have experienced a collapsed lung recently or are at risk of developing one, it's important to consult with your doctor before planning any air travel. They will assess your condition and determine if it's safe for you to fly.

In some cases, a doctor may recommend waiting until the lung has completely healed before flying. In other cases, they may give you specific guidelines and precautions to follow during the flight, such as limiting your activity level, avoiding sudden changes in altitude, or using supplemental oxygen.

Always prioritize your health and safety when making decisions about air travel. If you have concerns or questions, it's best to consult with a medical professional.
