血压的示波显示,不仅可以显示高、低压,还可显示心血管某些结构机能的特性。根据波形分析,可了解动脉的顺应性(compliance)。通过对脉搏波形面积的换算,可求得每搏输出量、动脉扩张程度、外周阻力等参数。但进行示波显示,只有用电子血压计方能实现。一、设计原理 Oscillographic oscilloscope showed that not only can display high and low pressure, but also show some structural features of cardiovascular. According to the waveform analysis, you can understand the arterial compliance (compliance). Through the conversion of the pulse waveform area, can be obtained stroke volume, arterial expansion, peripheral resistance and other parameters. However, the oscilloscope showed that only with electronic sphygmomanometer can be achieved. First, the design principle
