What kind of chest injuries are common due to air convection in the lungs

Intrapulmonary gas convection is commonly seen in closed and open chest injuries.

Intrapulmonary gas convection is often closely related to chest injuries, especially closed pneumothorax and open pneumothorax. Both chest injuries result in a dynamic imbalance of gases within the pleural space, thereby triggering intrapulmonary gas convection.

Closed pneumothorax is often caused by rib fractures puncturing the visceral pleura. At this time, the rupture of the lung tissue injury allows air to enter the pleural space, and then the wound quickly closes, causing convection of air in the lungs. In this case, although the negative pressure in the thoracoabdominal cavity has limited effect, it may still cause partial atrophy of the injured side of the lung.

Open pneumothorax is more serious and is usually caused by sharp objects such as blades or shrapnel stabbing the chest wall and pleura. This damage allows the pleural cavity to communicate with the outside world, allowing air to freely enter and exit with breathing, which not only causes gas convection in the lungs, but also seriously affects respiratory function. When inhaling, a large amount of air flows into the pleural cavity, compressing the lung on the injured side and pushing it to the healthy side; when exhaling, the air is discharged through the wound, causing mediastinal flutter, further aggravating the respiratory disorder.

Gas convection in the lungs requires prompt diagnosis and treatment to avoid further damage to respiratory function. If symptoms of discomfort occur, seek medical attention promptly.
