Orthostatic intolerance occurs in humans because standing upright is a fundamental stressor, so requires rapid and effective circulatory and neurologic compensations to maintain blood pressure, cerebral blood flow, and consciousness. When a human stands, about 750 ml of thoracic blood are abruptly translocated downward.
A related condition, orthodeoxia, describes the clinical finding of low oxygen saturation in the upright position, which improves when lying down. [3] Platypnea and orthodeoxia (low oxygen levels when in upright posture) can co-exist, and this combination is named platypnea-orthodeoxia syndrome. [4] [5] The syndrome is considered extremely rare ...
In the case of an individual standing quietly upright, the limit of stability is defined as the amount of postural sway at which balance is lost and corrective action is required. [ 6 ] Body sway can occur in all planes of motion, which make it an increasingly difficult ability to rehabilitate.

Variations in the angle are denoted by high Fowler, indicating an upright position at approximately 90 degrees and semi-Fowler, 30 to 45 degrees; and low Fowler, where the head is slightly elevated." [1] It is an intervention used to promote oxygenation via maximum chest expansion and is implemented during events of respiratory distress. Fowler ...
