Description
Lower body negative pressure (LBNP) involves the application of reduced pressure usually to that portion of the body below the level of the iliac crests. LBNP is used as a simulator of orthostatic stress and a preventer of cardiovascular deconditioning. At levels ranging from 40 to 60 mm Hg (53 x 102 to 80 x 102 N/m2) as determined by individual tolerance, LBNP produces changes in heart rate and blood pressure similar to those resulting from upright tilting.
