A Comparative Study on Effects between Wrist Blood Pressure Monitor and Upper Arm Cuff Sphygmomanometer Measurements

Objective To determine the accuracy of electronic wrist blood pressure monitor.Methods In 98 cases of randomly selected inpatients,49 patients aged 18 to 55 were divided into young-middle-aged group,and another 49 patients aged 55 to 78 were divided into old-aged group,whose blood pressures were measured by wrist sphygmomanometer and upper arm cuff blood pressure monitor respectively.Results In the young-middle-aged group,blood pressures had no statistical significance(P 0.05);in the old-aged group,systolic blood pressures had no statistical significance(P 0.05);diastolic blood pressures had significant difference(P 0.05).Conclusion Wrist blood pressure monitor used in young-middle-aged patients has high accuracy and reliability,but nurses should be careful to measure for elderly patients over the age of 55.
