432 The second trauma patient

Upon hearing the driver's account, Lin Feng's first reaction was that this person had a pneumothorax!

The pleural cavity, consisting of the parietal and visceral pleurae, is a sealed potential space devoid of air. Any rupture of the pleura allowing air to enter this space is known as pneumothorax. At this point, the pressure within the pleural cavity increases, and negative pressure may turn into positive pressure, compressing the lungs and obstructing venous return, causing varying degrees of pulmonary and cardiac dysfunction.

Pneumothorax is classified into closed, open, and tension types.

This driver suffered a pneumothorax due to trauma from a car accident, and since there were no wounds on the chest, it ruled out an open pneumothorax.

As to whether it was a tension pneumothorax or a closed pneumothorax, that would require an X-ray scan to determine.

However, Lin Feng had the "Technique of Inner and Outer Understanding," making a standard diagnosis different.
