Rapid oscillometric blood pressure measurement compared to conventional oscillometric measurement.

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.
