Pulmonary barotrauma occurs when there is damage to the lung tissue caused by a rapid or excessive change in air pressure, often seen in divers or individuals exposed to sudden pressure changes. It can lead to serious complications such as pneumothorax, arterial gas embolism, or subcutaneous emphysema if not managed promptly and effectively.

Pulmonary Barotrauma

Lung tissue is a specialized biological structure designed for efficient gas exchange, composed of alveoli, bronchioles, and blood vessels. Its health is crucial for respiratory function and is affected by various diseases such as pneumonia, emphysema, and lung cancer.

Lung Tissue

Air pressure is the force exerted by the weight of air molecules on a surface, and it decreases with altitude because there is less air above to exert pressure. It is crucial for weather patterns, aviation, and the functioning of various biological and mechanical systems on Earth.

Serious complications

Pneumothorax is a medical condition where air enters the pleural space, causing the lung to collapse partially or completely, leading to impaired breathing and potential respiratory distress. Prompt diagnosis and treatment are crucial to prevent complications, which may include chest tube insertion or surgery in severe cases.

Pneumothorax

An arterial gas embolism occurs when gas bubbles enter or form in the arterial circulation, leading to potential blockage of blood flow to vital organs and tissues. This condition is most commonly associated with diving accidents but can also result from medical procedures, trauma, or decompression sickness.

Arterial Gas Embolism

Subcutaneous emphysema is a medical condition characterized by the presence of air or gas in the subcutaneous layer of the skin, typically resulting from trauma, surgery, or infection. It often presents as swelling and a crackling sensation under the skin, and while it can resolve spontaneously, it may require intervention if associated with underlying injuries or respiratory compromise.
