Background. To assess the agreement between a new automatic device (FS-20D) using a cuff-oscillometric method to measure arterial blood pressure (BP) in the fingers and a standard mercury sphygmomanometer. Methods. The blood pressure measurements were taken in a sequential order, in a sample of both normotensive subjects (n. 57) and slight to moderate hypertensive patients (n. 28) without vascular complications. Results. The mean sphygmomanometer-monitor difference was 0.52±4.57 mmHg for systolic and 0.25±4.41 mmHg for diastolic values; the agreement limits were: SBP -8.6÷9.6 mmHg, 95% CI: -0.5÷1.5; DBP: -8.6÷9.1 mmHg, 95% CI: -0.7÷1.2. The grade of agreement between the monitor and the sphygmomanometer was “A” (British Hypertension Society) for both systolic and diastolic values (difference of readings <5 mmHg: 82%; <10 mmHg: 97% for systolic blood pressure, 98% of diastolic blood pressure). Conclusions. The monitor was proved to be reliable with a good level of precision and accuracy. The FS-20D monitor may be used in self-monitoring of blood pressure of patients with slight to moderate hypertension.

The blood pressure measurements were taken in a sequential order, in a sample of both normotensive subjects (n. 57) and slight to moderate hypertensive patients (n. 28) without vascular complications. Results. The mean sphygmomanometer-monitor difference was 0.52±4.57 mmHg for systolic and 0.25±4.41 mmHg for diastolic values; the agreement limits were: SBP -8.6÷9.6 mmHg, 95% CI: -0.5÷1.5; DBP: -8.6÷9.1 mmHg, 95% CI: -0.7÷1.2. The grade of agreement between the monitor and the sphygmomanometer was “A” (British Hypertension Society) for both systolic and diastolic values (difference of readings <5 mmHg: 82%; <10 mmHg: 97% for systolic blood pressure, 98% of diastolic blood pressure).

The FS-20D monitor may be used in self-monitoring of blood pressure of patients with slight to moderate hypertension.
