Reviving lower body negative pressure as a countermeasure to prevent pathological vascular and ocular changes in microgravity

Abstract Mitigation of spaceflight-related pathologies such as spaceflight-associated neuro-ocular syndrome (SANS) and the recently discovered risk of venous thrombosis must happen before deep space exploration can occur. Lower body negative pressure (LBNP) can simulate gravitational stress during s...
