Pneumothorax is mainly caused by various reasons that allow air inside the lungs to enter the pleural cavity, resulting in the accumulation of gas and the compression of the lung, reducing its volume. Clinically, for patients with lung compression not exceeding 30%, a conservative approach is typically chosen, which involves allowing the patients to heal naturally. For these patients who wish to accelerate their recovery, it is generally recommended to inhale high concentrations of oxygen, which can aid in the healing of the lungs. Additionally, it is important to increase nutrition and protein intake to enhance lung repair and recovery.
