Description

TECHNICAL FIELD

[0002] Pneumothorax refers to the abnormal entry of gas into the pleural cavity, resulting in partial or complete collapse of the lung. Common causes include lung disease or external force, causing lung tissue and visceral pleura to rupture, or small alveoli or lung bullae near the lung surface to rupture, causing air to escape into the pleural cavity. Pneumothorax is one of the common emergencies in the respiratory department. If not diagnosed and treated in time, it may cause severe respiratory difficulty and even endanger life. Therefore, in the preliminary diagnosis process, ultrasonic equipment is often used for rapid exploration to evaluate the pleural sliding sign, comet tail sign, lung point and other characteristic ultrasonic manifestations, providing an important basis for early identification and intervention.
