(17 April 2013) --- In support of the Blood Pressure Regulation Experiment (BP Reg), Expedition 35 Commander Chris Hadfield of the Canadian Space Agency is pictured after having set up the Human Research Facility (HRF) PFS (Pulmonary Function System) and the European Physiology Module (EPM) Cardiolab (CDL) Leg/Arm Cuff System (LACS) and conducting the first ever session of this experiment. The test, which will be repeated using other crew members as well, will help to identify the astronauts who could benefit from countermeasures before returning to Earth. Thus, this method has great potential for astronaut health monitoring during future long-term space flights and it also has important implications for testing of individuals on Earth, especially the elderly, who are at risk for fainting. The research will also allow demonstrating the feasibility of obtaining a set of indicators of overall cardiovascular regulation from the non-invasive measurement of continuous blood pressure.
