How does anesthesia affect your lungs?

Most anesthetics cause a loss of muscle tone that is accompanied by a fall in the resting lung volume. The lowered lung volume promotes cyclic (tidal) or continuous airway closure. High inspired oxygen fractions cause rapid absorption of gas behind closed airways, resulting in atelectasis.

Can anesthesia damage your lungs?

In rare cases, the injection can cause a collapsed lung if the needle is inserted in the chest area. Nerve damage from regional anesthesia also is a rare complication.

Abstract. Pulmonary gas exchange is regularly impaired during general anaesthesia with mechanical ventilation. This results in decreased oxygenation of blood. A major cause is collapse of lung tissue (atelectasis), which can be demonstrated by computed tomography but not by conventional chest x-ray.

Can anesthesia cause respiratory distress?

Recent findings: General anesthesia and surgery are the main causes of postoperative respiratory complications. Atelectasis, a common respiratory complication, may contribute to pneumonia and acute respiratory failure.
