Cardiovascular Response in LBNP Examination

Original language description

Lower body negative pressure examination technique is applied as one of the possibilities for preliminary estimation of the pilot's plus gravitational acceleration tolerance. It partly replaces demanding and expensive examinations in a human centrifuge.Current LBNP examinations are accomplished with one step exposure at the negative pressure level of -70 mmHg with achievement of this value in one second. Pilots are examined in the sitting position with the possibility to tilt the chamber backward. Physiological responses from the blood pressure and heart rate point of view are in an LBNP examination similar as in the +3.5 Gz in a human centrifuge and mostly correspond to the gravitational acceleration +4.5 Gz during flights in aircraft. LBNP examinations allow to evaluate entirely the orthostatic part of the actual cardiovascular response as the basic part of the complex resistance to overloading. Possibilities of the prediction of the low level of +Gz tolerance were proved.
