[Application of the sphygmogram in evaluation of pilots' cardiovascular function in resting condition]

With the purpose of exploring a new method for aerospace medical monitoring, a newly developed method--sphygmogram was used in 169 pilots. The results showed that these pilots could be divided into three types by the features of their resting sphygmogram. Among them, with respect to their cardiovascular function, 71 (about 42%) were "completely normal", 79 were "essentially normal", and 19 had some changes in cardiovascular function. It is considered that the status of cardiovascular function of the pilots can be distinguished with the newly developed method of sphygmogram. It suggests that it is important to make dynamic observations of pilots' cardiovascular function and strengthen the medical care for those who show certain changes in their cardiovascular function as revealed by the sphygmogram.
