Pulse diagnosis had faced a serious problem which was no objective standard in education, clinical and research fields. We tried to establish standardized operating protocol of pulse diagnosis to set up a preload-displacement database with help of a measuring device to provide the basis of development in sphygmograph and the application in clinic and education.
We divided 68 healthy individuals into four groups according to their body mass index (BMI). With the preload-displacement measuring device, a doctor took the pulse by a standardized operating protocol and recorded the preload and displacement of the upper and lower border in tsun, guan and chi of the pulse area. Also, we analyzed the effect of gender and BMI in preload and displacement.
The result showed that the preload pressure of the upper border ranged from 0 to 11.82 mmHg, and 0.37 to 199.77 mmHg in lower border. The maximum displacement between the upper and lower border was 10.27 mm. Both gender and body mass index were statistically related to preload rather than displacement. We also established a definite model for measuring the most important two parameters in pulse diagnosis, and the model could be used to define the pulse conditions. Moreover, the database would provide a fundamental basis for further research and device development in pulse diagnosis in the future.
