Abstract：Objective To reveal and quantitatively analyze the influence of postural changes on male and
female radial pulse wave. Methods 20 healthy students were enrolled in this study to collect their radial
pulse wave by using dual pulse signal acquisition equipment at the tilting bed with 0 degrees, 45 degrees,
90 degrees; and then, the basic hemodynamic parameters and the model parameters on dual Windkessel
model were calculated. The hemodynamic parameters of male and female were analyzed and compared
by paired t-test. Results The results showed that with the increase of body position (The subject along
with tilt bed-from 0 degrees to 45 degrees and then to 90 degrees)both male and female heart rate (HR)
and sub-endocardial myocardial viability rate (SEVR) were significant increased (P<0.05); radial artery
pressure full time (Tdown) was significant decreased (P>0.05), however, other hemodynamic parameters
did not change significantly with body position (P>0.05); both arterial compliance (C1) and abdominal
aortic compliance (C2) became smaller with the increase of body position in male and female, peripheral
resistance (R) became larger. HR, R, u-Lratio of male and female have statistical difference （P<0.05）;
there were no statistically significant differences in K value, Tup, Tdown, TLVET, LM-Pratio, dAI, SEVR, u-dratio,
C1 and C2 between males and females (P>0.05). Conclusion Body position has an obvious influence on
radial artery and there are differences between male and female hemodynamic parameters, which should
be paid more attention in clinic.
