The length of time a patient with a severe lung perforation can live is related to his or her specific condition and cannot be generalized. Severe perforation of the lung is usually the result of inflammation or trauma. If the lung and chest wall tissue is severely perforated due to trauma, the perforated rupture will need to be surgically sutured and a closed chest drain will be left in place after surgery and treated with antibiotics. Patients usually survive for a long time after the lung tissue has healed and can have the same life cycle as a normal person. If the lung perforation is severe due to a ruptured alveolus or spontaneous pneumothorax, closed chest drainage may be performed, which usually results in gradual recovery within 1 week and has no effect on life expectancy after healing. If the severe lung perforation is diffusely distributed, it can seriously affect the patient’s respiratory function and even cause respiratory failure or multi-organ failure, which can affect the patient’s survival time, and most patients can only survive for 1 year. In addition, patients are advised to avoid spicy and irritating foods, which can irritate the tracheal mucosa and aggravate cough, asthma, palpitations and other symptoms, and avoid gas-producing foods, such as sweet potatoes and leeks, which are unfavorable to the propagation and descent of lung qi, and should consume more alkaline foods.
