PHYSIOLAB: a cardiovascular laboratory.

Abstract

PHYSIOLAB is a cardio-vascular laboratory designed by CNES in cooperation with IMBP, with double scientific and medical goals: -a better understanding of the basic mechanisms involved in blood pressure and heart rate regulation, in order to predict and control the phenomenon of cardio-vascular deconditionning. -a real-time monitoring of cosmonauts during functional tests. Launched to the MIR station in 1996, this laboratory was set up and used for the first time by Claudie Andre-Deshays during the French mission "Cassiopeia". The scientific program is performed pre, post and in-flight to study phenomena related to the transition to microgravity as well as the return to the earth conditions. Particular emphasis was placed on the development of the real-time telemetry to monitor LBNP test. This function was successful during the Cassiopeia mission, providing the medical team at TSOUP (MIR Control Center in Moscow) with efficient means to control the physiological state of the cosmonaut. Based on the results of this first mission, IMBP and CNES will go on using Physiolab with Russian crews. CNES will take advantage of the upcoming French missions on MIR to improve the system, and intends to develop a new laboratory for the International Space Station.
