Doctor's answer:
Hello, patients with mild pneumothorax may not have clinical symptoms, and their signs are often not obvious. Most are discovered during X-ray examinations. In severe cases, only accelerated breathing can be observed. In severe conditions, the sick child may become restless, experience difficulty breathing, and develop cyanosis. Typical symptoms include the affected chest being larger than the healthy side, intercostal spaces being filled, and a hollow sound when tapped. Breath sounds may be diminished or absent upon auscultation. When the pressure within the pleural cavity is higher than atmospheric pressure, it is referred to as a tension pneumothorax, which can cause the mediastinum to shift toward the healthy side.
