Pneumothorax refers to the accumulation of air that occurs when air enters the pleural cavity, a closed space, which is known as pneumothorax. The most common clinical manifestations of pneumothorax depend on the speed of onset, the degree of lung compression, and the etiology of the primary disease causing the pneumothorax. Typically, patients may experience a high level of mental tension, fear, restlessness, shortness of breath, and a feeling of suffocation. Some individuals may sweat, have an increased pulse rate, with the most prominent symptom being difficulty in breathing. Additionally, some patients may experience coughing and chest pain, and some may develop mediastinal emphysema, leading to gradually worsening respiratory difficulties, and even manifestations of shock such as a drop in blood pressure.
