Abstract:
Objective To compare blood pressures results measured by automated sphygmomanometer and standard mercury sphygmomanometer,and to investigate the application of measurements consistency evaluation method in accurate measurement of automated sphygmomanometer.Methods Intraclass correlation coefficient was used to estimate the reliability of repeated measurements,and Bland -Altman method was adopted to evaluate the consistency between automated sphygmomanometer and standard mercury sphygmomanometer.Meanwhile,the results were compared with protocol of European Society of Hypertension.Results The tested automated sphygmomanometer did not adapt to the criteria of European Society of Hypertension.The intraclass correlation coefficient of mercury sphygmomanometer was 0.937 for systolic blood pressure,0.849 for diastolic blood pressure.The intraclass correlation coefficient of tested sphygmomanometer was 0.944 for systolic blood pressure,0.929 for diastolic blood pressure.The 95% consistency interval was(-10.20 to 16.94)mmHg for systolic blood pressure and(-6.25 to 11.69)mmHg for diastolic blood pressure.Conclusion Normally,Bland-Altman method has the same judgment result with protocol of European Society of Hypertension.
