Whether a small amount of mediastinal pneumoperitoneum is important or not is mainly a matter of observing the subsequent changes. If a small amount of air buildup is gradually absorbed, it is not a problem and is not important; if the amount of air buildup continues to increase and causes abnormalities in cardiopulmonary function, it is important. A small amount of pneumothorax in the mediastinum may be related to alveolar rupture, but most of the pneumothorax will gradually disappear on its own and is not a cause for concern. Tension pneumothorax is a serious condition that requires treatment if the volume of air continues to increase and affects cardiopulmonary function. If the pneumothorax continues to increase, accompanied by obvious heart beat abnormality and respiratory limitation, it is necessary to consult a doctor for observation, and carry out standardized treatment under the guidance of the clinician after confirming the specific condition, so as to avoid delaying the condition.
