Summary
Healthy individuals showed adaptive changes in coronary circulation during Coriolis acceleration tests. Monitoring coronary circulation is recommended for flight medical evaluations.
Area of Science:
- Cardiovascular physiology
- Aerospace medicine
Background:
- Coriolis accelerations can impact physiological functions.
- Understanding cardiovascular responses is crucial for aviation safety.
Purpose of the Study:
- To investigate time-course variations in coronary circulation and cardiac output.
- To assess cardiovascular adaptation to Coriolis accelerations, with and without hypoxia.
Main Methods:
- Measurements of coronary circulation and cardiac output in healthy subjects.
- Exposure to continuous cumulation of Coriolis accelerations.
- Exposure to Coriolis accelerations combined with acute hypoxia.
Main Results:
- Adaptive changes in coronary circulation were observed.
- Specific cardiovascular responses varied between conditions.
Conclusions:
- Coronary circulation adapts to Coriolis acceleration stress.
- Monitoring coronary circulation is advised during vestibulometric testing for flight personnel medical expertise.
