Abstract
This study was designed to assess the accuracy of the Visomat S home blood pressure recorder. Both the conventional mercury sphygmomanometer and intra-arterial pressure transducer were used as standards for comparison. The accuracy of the Visomat was assessed for 24 normotensive subjects and then for 24 hypertensive subjects using the conventional sphygmomanometer as the standard for comparison. The Visomat was found to give an accurate measure of the systolic and diastolic (phase V) pressures registered by the sphygmomanometer in both these groups of subjects. In a further study on eight subjects, it was shown that the Visomat also gave an accurate assessment of systolic and diastolic pressures measured directly with intra-arterial catheters. The design of the Visomat makes it very convenient for home blood pressure recording. It can be used by a patient unaided and a minimum of skill is required to obtain a reading. With its accuracy confirmed, the Visomat is a useful instrument for home blood pressure management.
