Details and patient eligibility

About

The study compares H2-BP, a wristband blood pressure monitor, with an auscultatory sphygmomanometer. Both devices are used on the same arm. After confirming wrist and upper arm circumference, H2-BP is operated by one measurer, while the auscultatory sphygmomanometer is simultaneously operated by two other measurers. Each subject undergoes alternating measurements of H2-BP on one wrist and the auscultatory sphygmomanometer on the same arm until three valid measurement pairs are obtained per subject, with a maximum of eight repetitions allowed. The two auscultatory sphygmomanometer measurers operate independently and cannot see each other's measurements during the test. Measurements are repeated for 10 to 30 minutes until three valid blood pressure values are obtained and recorded. Validity assessment variables are derived from the recorded values to evaluate the accuracy of H2-BP.
