When a pneumothorax occurs, if the compression of the lung is only 10% and there are no other complications and no serious lung disease, recovery will be quick after complete rest. Bed rest for more than 1 week is usually required. However, if there are serious complications, the pneumothorax, although only 10%, is slower to get well, and if the complication of infection leads to the occurrence of pus pneumothorax, the pneumothorax may be delayed for 2-3 months and will not recover. It is very important to use anti-infective drugs and to perform timely anti-inflammation. Otherwise, it may lead to systemic complications, such as sepsis is very dangerous and may lead to the appearance of death. It is necessary to choose the appropriate antibiotics for treatment according to the type of infection, and it is important to use intravenous drips, because the effect of oral drugs is often not enough.
