The goal of the EDOMP is to maintain crew health and safety during 13- to 16-day missions aboard the Space Shuttle. A
series of investigations has been designed to assess the medical status of the crewmembers and the environment where they
work. One EDOMP investigation tests a treatment to counteract negative cardiovascular responses, and the other monitors
the Spacelab environment to determine the growth of fungi and bacteria over the course of the mission.
After ingesting salt tablets and water, crewmembers are exposed to negative pressure in the LBNP device. This treatment
reduces cardiovascular deconditioning upon return to earth.
