体位对桡动脉脉搏波影响的量化分析
Quantitative Analysis of the Influence of Body Position on the Radial Pulse Wave
摘要
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.关键词
