Risk of Venous Thromboembolism During Spaceflight

In October 2024, NASA’s Office of the Chief Health and Medical Officer (OCHMO) initiated a working group to review the status and progress of research and clinical activities intended to mitigate the risk of venous thromboembolism (VTE) during spaceflight.

Hydrogen Sulfide (H2S) Independent Assessment

NASA’s Office of the Chief Health and Medical Officer (OCHMO) assembled a small working group to review hydrogen sulfide (H2S) Spacecraft Maximum Allowable Concentration (SMAC) values. The group met virtually three times during February and March 2023, and panel members submitted individual opinion statements in April 2023.
