Pneumothorax is primarily caused by various factors, both internal and external to the lungs, leading to a significant accumulation of gas within the chest cavity. Patients exhibit symptoms such as chest tightness, breathlessness, including coughing, chest pain, and other related symptoms, which are collectively referred to as pneumothorax. Patients with pneumothorax can be classified into mild and severe types. Generally, after the onset of pneumothorax, patients who only experience symptoms like panting, chest tightness, chest pain, or coughing, but maintain stable blood pressure and heart rate, are considered to have a mild condition. However, if in addition to these respiratory symptoms, the patient clearly exhibits a drop in blood pressure, a decrease in oxygen saturation, or a reduction in heart rate, these conditions are considered severe and require urgent treatment.
