Passive position means not being able to rely on one’s own strength to adjust or change the position of the limbs, and being in a fixed and uncomfortable state. Doctors will use different positions for relief treatment according to the different parts of the patient’s body injured by the disease. There are several clinical reasons for using different passive positions: 1. depillowed flat position: common in postoperative patients with intracranial anesthesia, the purpose is to prevent headaches caused by reduced intracranial pressure. 2, in the concave position: common in patients in shock, the purpose is to increase the amount of return blood, and thus increase cardiac output to reduce the risk of shock. 3, semi-sitting position: common in patients with inflammation in the abdomen or abdominal surgery, the purpose of this position is to reduce tension at the wound and relieve pain. 4, sitting position: common in patients with bronchial asthma, the purpose is to relieve respiratory distress, because such patients lying down will aggravate respiratory distress. 5.Lateral position: common in patients who need to do enema, or need to do anal and gastroscopic examination. 6.Head-high-foot-low position: common in patients who need to do cranial traction due to cervical fractures, to provide them with counter-traction. 7.Head-low-foot-high position: Commonly used in pregnancy when the fetal membranes rupture prematurely, to prevent uterine prolapse in this position.
