Comparison of a semi-automated sphygmomanometer with the clinical sphygmomanometer.

A semi-automated sphygmomanometer Stanley B-200 has been compared with the clinical sphygmomanometer in 500 college boys by using a blind simultaneous method. Stanley B-200 has shown significantly higher systolic blood pressure (14.8 mmHg, P smaller than 0.05) and diastolic blood pressure (3.8 mmHg, P smaller than 0;05). This device also recorded 15 false positive systolic and 12 false negative diastolic results (P smaller than 0.05).
