Human Life Research on ISS Russian Segment

Cardio-ODNT Experiment


Investigation of dynamics of basic factors of cardiac activity and blood circulation.


Investigation of responses of big and small circles of blood circulation when negative pressure affects the lower part of the body and the dependence of these responses on the initial status of the cardiovascular system.

Flight Equipment Used:

  • Gamma-1M hardware
    to record electrocardiogram, arterial pressure, rheograms of different vessel areas including rheoencephalograms.
  • Chibis pneumatic-vacuum suit
    to perform a test physical load when producing a negative pressure (from 10 to 60 mm Hg) to the lower part of the cosmonaut's body.

Expected Results:

Prediction of a cosmonauts' cardiovascular system state.
