- Abstract:
- This study investigates the time course of hemodynamic variables during and after simulated orthostasis (lower body suction at 55mmHg for 30 mins: LBNP-55). Individual strategies of blood pressure defense could be observed; LBNP-55 increased heart rate and reduced stroke volume, but was non-hypotensive. During 20 minutes post-LBNP, heart rate was decreased as well as stroke volume index below pre-LBNP values. The reduced cardiac index together with unchanged mean arterial pressure gave a highly significant increase of peripheral resistance after LBNP. The validity of stroke volume results under the experimental conditions given needs to be clarified.
