Accuracy of the SpaceLabs 90207, Novacor DIASYS 200, Del Mar Avionics Pressurometer IV and Takeda TM-2420 ambulatory systems according to British and American criteria

Abstract

Ambulatory blood pressure measurement, which has been confined to research for many years, is now an accepted investigation in clinical practice [ l ] . In an effort to ensure that the devices meet the requirements of clinical practice the British Hypertension Society (BHs) has published a comprehensive protocol for the evaluation of blood pressure measuring devices with special reference to ambulatory systems [2]. Four ambulatory systems, the SpaceIabs 90207 [3], the Novacor DIASYS 200 [4], the Del Mar Avionics Pressurometer IV [5] and the Takeda TM-2420 [6] have now been evaluated according to the BHS protocol. The evaluation was performed under standardized conditions for each ambulatory system, allowing comparison between devices.
