Cardiorespiratory response to lower body negative pressure.

Abstract

The cardiovascular effects of supine lower body negative pressure (LBNP, 0 mm Hg, -8 mm Hg, -15 mm Hg, -25 mm Hg, -35 mm Hg, and -45 mm Hg) were studied in humans (n = 10). The LBNP's were applied in a random order (three per session) for 20 min, with 15 min between each LBNP. Leg blood flow, cardiac output (Q), stroke volume (SV) and estimated lung blood… (More)
