Pulmonary Emboli (Air)

Pulmonary emboli (air) occur when air bubbles enter the blood vessels of the lungs, blocking blood flow. This condition affects the respiratory system and can cause sudden difficulty breathing, chest pain, and low oxygen levels. The air bubbles prevent blood from reaching parts of the lung, which can damage lung tissue and strain the heart. It often happens during medical procedures involving veins or surgery near large blood vessels. Symptoms may include shortness of breath, rapid heart rate, and chest discomfort. This blockage can be life-threatening if not recognized and treated promptly.

Pulmonary emboli (air) is a form of embolism characterized by the obstruction of the pulmonary arterial circulation by intravascular air bubbles. The core pathology involves the entry of air into the venous system, typically through trauma, surgical procedures, or central venous catheter manipulation, leading to embolization in the pulmonary vasculature. This results in impaired pulmonary perfusion, ventilation-perfusion mismatch, and potential right ventricular strain or failure. The condition is clinically significant due to its potential to cause acute respiratory distress, hypoxemia, and cardiovascular collapse. Diagnosis requires high clinical suspicion in the context of risk factors and sudden respiratory or hemodynamic changes. The volume and rate of air entry determine the severity of the embolism and clinical outcome.
