Fowler position

(fowl′ĕr) [George R. Fowler, U.S. surgeon, 1848–1906] A semi-sitting position. The head of an adjustable bed can be elevated to the desired height to produce angulation of the body, usually 45° to 60°. The knees may or may not be bent. A wedge support can be used to elevate the patient’s head and back if an adjustable bed is not available. The position is used to facilitate breathing and drainage and for the comfort of the bedridden patient while eating or talking.

 NOTE: The Fowler position has three variations: high (sitting upright in bed), regular (head or torso elevated 45° or more), and low or semi-low (head and torso elevated to 30°). SEE: illus.; dorsal recumbent position for illus.

The intraepidermal ducts of the apocrine glands become obstructed and eventually rupture.
