Small amount of pneumothorax treatment methods are as follows: 1, conservative treatment, such as absolute bed rest, avoid activities, because activities will increase lung capacity, which is not conducive to small amount of pneumothorax absorption; 2, patients can be oxygenated in the nearest clinic or hospital, because oxygen can help small amount of gas absorption and promote the repair of broken pleura; 3, if a small amount of pneumothorax is not quickly absorbed through conservative treatment, then pleural puncture drainage is needed, which can promote rapid gas absorption; 4. If the patient has underlying disease and poor basic lung function itself, even a small amount of pneumothorax, the symptoms will be heavier. At this time, there is no need to observe the preoxygenation process, and pleurodesis drainage should be actively given to help them recover as soon as possible and promote pneumothorax absorption.
