Forced position refers to a fixed and uncomfortable state in which the patient is unable to adjust or change the position of the limb by his/her own strength. The common forced positions are decubitus position, mid-concave position, semi-sitting position, telescope position, lateral position, head high foot low position and head low foot high position. Diagnosis and differentiation: 1. Automatic position refers to the body moving freely without any restriction, which is seen in normal people or in the early stage of certain mild diseases or illnesses. 2, forced position (1) forced sitting position: also known as sitting breathing, this position is easy to breathe, and because the lower extremity position is lower than the heart, so that blood flow back to the heart to reduce the burden on the heart, mostly seen in patients with severe heart failure and patients with pulmonary insufficiency. (2) forced prone position: this position can reduce the tension of the muscles of the low back, commonly seen in patients with spondylitis, spinal trauma, etc. (3) forced lateral position: seen in patients suffering from pleurisy on one side and a large amount of pleural effusion on one side, because this can reduce the pain and enable the respiratory muscles and lungs on the healthy side to breathe compensatorily to reduce respiratory distress. (4) Forced supine position: the patient lies on his back with his legs curled, which reduces abdominal muscle tension and pain, as seen in certain pains caused by abdominal disorders such as peritonitis. (5) Forced standing position: It occurs when the patient suddenly stands up while walking and covers the precordial area with his hands, and then continues to walk later. Most of them are caused by angina attack, and then serious or even fainting or sudden death, if you also have similar attacks, you need to go to the hospital immediately for examination, and carry the necessary drugs for urgent use. (6) Forced squatting: Patients feel palpitations or difficulty in breathing during activities, and adopt squatting or knee-chest position to relieve symptoms, commonly seen in cyanotic congenital heart disease. (7) Tossing and turning position: It is shown that the patient tosses and turns in bed and keeps changing position.
