[Evaluation of the hemodynamic indices of a pilot in flight]. / Otsenka nekotorykh pokazatelei gemodinamiki u letchika v polete.

Coronary circulation and systolic and diastolic time intervals were measured in one-seat high-manoeuvrability aircraft pilots during 22 flights. The effective coronary blood flow values varied significantly and reached maximum during landing. In some cases these changes were very large, suggesting a low level of conditioning and physiological reserves. It is recommended to monitor coronary circulation inflight.

[Diagnosis of fatigue in flight personnel based on cardiodynamic data]. / Diagnostika utomleniia u letnogo sostava po dannym kardiodinamiki.

By Doppler cardiography systolic acid diastolic time time intervals and cardiac contractility were measured in 22 pilots during interflight periods. Certain cardiodynamic parameters showed significant differences in the pilots as compared to 24 nonpilots. It is indicated that these parameters should be regularly monitored between flights in order to prevent fatigue of the flight personnel, to detect early developments of cardiac insufficiency, and maintain pilot longevity.
