BackgroundThere have been few reports studying the necessary interval between blood pressure measurements, after the initial rest period.MethodsBlood pressure was measured in 50 patients using the conventional oscillometric technique (COT) and the rapid oscillometric technique (ROT).ResultsThe 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).ConclusionsIt 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.
