Abstract
Sphygmomanometry is the most common technique of blood pressure (BP) determ ination. In order to study effects of predictability and controllability in sphygmomanometric BP measurements, 72 normotensive healthy subjects were e xamined. BP was determined continuously and non-invasively using a Finapres device (Penaz-technique) and by sphygmomanometry. Five sphygmomanometric m easurements took place, during the fourth the arm cuff was inflated to 300 mmHg, the others were done with a pressure of 175 mmHg. Subjects were rando mly assigned to one of three groups: In one group the recordings were unpre dictable to the subject, in the second group measurements were announced 1 min before cuff inflation took place, and in the third group, subjects coul d decide when the sphygmomanometric recordings should occur. With unpredict able measurements systolic and diastolic BP decreased (approx. 5 mmHg). Whe n sphygmomanometric recordings were controllable or predictable to the subj ect BP remained relatively stable. We would suggest that automatic BP devic es (e.g. in ambulatory BP monitoring) should generally work with acoustic s ignals, making cuff inflation predictable for the subject.
