[0002] Postural drainage refers to the gravity drainage of secretions, which makes the diseased lung in a high position, and the opening of the drainage bronchus is downward, so that the sputum is coughed out along the trachea by gravity, which is helpful for the removal of sputum. It is mainly used for: large-scale atelectasis caused by secretions or cell retention; structural abnormalities such as bronchiectasis, cystic fibrosis or lung abscess, which cause secretions to accumulate and cannot be eliminated for a long time; acute infection of patients with COPD, pulmonary fibrosis, etc. who are unable to expel secretions due to limited breathing; or cough weakness in elderly or cachectic patients, neuromuscular diseases, postoperative or traumatic pain, or tracheotomy patients. That is, the suitable population is patients with symptoms such as atelectasis, bronchiectasis, cystic fibrosis, lung abscess, pulmonary fibrosis, and weak cough. Different postures are adopted for postural drainage according to the location of the patient's lesion. If the lesion is in the lower lobe, lingula, or middle lobe, the head is low and the feet are high, slightly lying on the healthy side; if it is in the upper lobe, sit or other appropriate postures are adopted to facilitate drainage.
