A woman placed in the<unk>  (in this case, 45 degrees) In medicine,<unk>  is a standard patient<unk>  in which the patient is seated in a semi-sitting<unk>  (45-60 degrees) and may have knees either bent or straight. Variations in the angle are denoted by high<unk> , indicating an upright<unk>  at approximately 90 degrees and semi-Fowler, 30 to 45 degrees; and low<unk> , where the head is slightly elevated." It is an intervention used to promote oxygenation via maximum chest expansion and is implemented during events of respiratory distress.<unk>  facilitates the relaxing of tension of the abdominal muscles, allowing for improved breathing. In immobile patients and infants, the<unk>  alleviates compression of the chest that occurs due to gravity.<unk>  increases comfort during eating and other activities, is used in postpartum women to improve uterine drainage, and in infants when signs of respiratory distress are present.<unk>  is also used when oral or nasal gastric feeding tubes have been implemented as it minimizes the risk of aspiration. Peristalsis and swallowing are aided by the effect of gravitational pull. It is named for George Ryerson<unk> , who saw it as a way to decrease the mortality of peritonitis: Accumulation of purulent material under the diaphragm led to rapid systemic sepsis and septic shock, whereas pelvic abscesses could be drained through the rectum.
