ABSTRACT
Objective To explore the distinguishing method and threshold of optimum pulse pressures on Cun pulse and Chi pulse to solve the problem how to exert pressure upon Three Regions Pulse Detecting Instrument.Methods Totally 55 subjects meeting the inclusion criteria were collected.The data of optimum pulse pressures on Cun Guan Chi of the same hand of the same tested person were collected respectively and the comparative analysis on the data was carried out.Results In normal subjects,the attenuation degree of optimum pulse pressures on Guan pulse compared with Cun pulse was 0.189?0.053,and the attenuation degree of optimum pulse pressures on Chi pulse in comparison with Guan pulse was 0.226?0.044.Conclusion Through calculating the attenuation degree of optimum pulse pressures reasonably,the identified threshold of Cun and Chi pulses can be judged from the threshold of Fu-superficial,Zhong-medium,and Chen-deep of Guan pulse.
