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.

OBJECTIVE:

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

TASKS:

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.

EXPECTED RESULTS:

Prediction of a cosmonauts' cardiovascular system state.
