Some patients with heart disease, or patients with weak spontaneous breathing ability, should raise the bedside by more than 45 when lying in a semi-recumbent position. If the head of the bed in the semi-recumbent position is too low, it will lead to dyspnea, and the patient's respiratory secretions will easily block the respiratory tract, which will lead to the patient's life-threatening.
Semi-recumbent position can also make abdominal exudate flow into pelvic cavity, which is beneficial to drainage and can avoid the formation of subphrenic abscess. The semi-supine position can also alleviate the symptoms of poisoning, because when the semi-supine position is adopted, the drainage fluid flows to the pelvic cavity, reducing the absorption of toxic substances.
The difference between supine position and supine position
First, the angle difference.
1, supine is 180 degrees, which means lying flat completely.
2, supine position does not require 180 degrees, as long as the body is supine. People are sitting on a fitness chair, and their upper body is lying on the back of the chair at a certain angle, not lying flat.
3. All similar supine positions can be called supine positions as long as the whole body is not flat at 180 degrees. As for whether you still need to bend your knees, it depends on the action requirements.
Second, the action difference
1, supine position refers to a state in which the longitudinal axis of the human body is as parallel as possible to the ground.
2. supine position refers to a state in which the human body is in supine position, chest, abdomen and face up.
