What is the difference between pulmonary maculoplasm and pneumothorax? Pneumomediastinum and pneumothorax have similarities, so sometimes misdiagnosis may occur. It is important to identify diseases that have similar symptoms to avoid mistakes. If you make a mistake, it can delay the disease or even put the patient’s life at risk. The following is a brief description of the differentiation between pulmonary herpes and pneumothorax. Patients with small pneumothorax and simple pneumothorax have no symptoms, but when the pneumothorax grows to a large size, the patient will experience chest tightness and shortness of breath. Most patients with pneumothorax have an acute onset and experience sudden chest pain, chest tightness, difficulty breathing, and a dry cough. If a pulmonary blister ruptures, it may trigger a spontaneous pneumothorax, and the symptoms of secondary pneumothorax are usually more severe. Some pulmonary blisters located around the lungs may be mistaken for pneumothorax when examined by X-ray. Some pulmonary blisters are congenital and may remain that size and state for a long time without causing any harm to the body. In some cases, it is caused by an obstruction of the bronchial valve, which is a slow onset and has no special symptoms. The lung lesion can be clearly seen by chest fluoroscopy. The edges of the pulmonary blister are not visible as a line of pneumothorax, but small streaks can be seen within the blister, which are remnants of lung lobules or blood vessels. Pneumomediastinum is distended in the periphery and presses the lung toward the apical region, the angle of the rib diaphragm, and the angle of the cardiac septum. In contrast, the examination of a patient with pneumothorax shows a transilluminated band on the outside of the chest on which no lung stripe is visible. In addition to examination by X-ray, pneumothorax patients can also measure the air pressure by puncturing the accumulated gas in the chest cavity, and if the gas can be extracted and the pressure is positive, it means the patient has pneumothorax. Through the above introduction, I believe that you have understood the identification method of pneumothorax and pneumothorax. In addition to looking at the patient’s symptoms, we should also check through some auxiliary examination means, and then analyze the condition and make the identification.
