gravity-dependent positionPlacement of a limb so that its distal end is lower than the level of the heart. Gravity affects the fluids within the limb, drawing or retaining them to the distal aspect. When limbs, esp. injured limbs, are placed below the level of the heart, interstitial pressure is increased, encouraging the formation and retention of edema within the extremity. See also: position |
