Description
Present state of knowledge: Lower body negative pressure (LBNP), venous occlusion thigh cuffs, and breathing through an impedance threshold device (ITD) have all been used during various research projects on the ISS, but not in a systematic way to determine the effectiveness as countermeasures to prevent SANS findings. It is unknown if the magnitude of effect of these countermeasures on the reversal of the headward fluid shift during spaceflight is similar to the effect that occurs during strict head-down tilt bed rest or whether these can be combined with other countermeasures to prevent SANS during spaceflight.

Research approach: Flight testing of the combined countermeasure will start with a flight demo of the mechanical component of the countermeasure to verify that in-flight use is feasible, followed by full testing of the integrated countermeasure during long-duration flights.
Target for Closure
Validation of the effectiveness of the final integrated SANS countermeasure.
