Rapid oscillometric blood pressure measurement compared to conventional oscillometric measurement

Abstract

BACKGROUND: There have been few reports studying the necessary interval between blood pressure measurements, after the initial rest period. METHODS: Blood pressure was measured in 50 patients using the conventional oscillometric technique (COT) and the rapid oscillometric technique (ROT). RESULTS: The difference between COT and ROT was -1.1 / -0.1 mmHg, which was not significantly different (p = 0.8 / 1.0) and the pulse difference was -0.8 beats per minute (p = 0.8). CONCLUSIONS: It is concluded that a 15-second interval between blood pressure readings is as accurate as a one-minute interval providing that these measurements are started after a 5-minute rest period.
