title: [How reliable is oscillometric blood pressure determination at the finger using the Omron device?].
abstract: The precision of oscillometric blood-pressure measurements on the finger with the model HEM-812F, manufactured by Omron, was compared to the standard method. The digital measurements from 180 inpatients (115.0 +/- 1.2 mmHg systolic, 68.8 +/- 0.8 mmHg diastolic) were significantly lower than oscillometric measurements from the upper arm using a Bosomat (121.3 +/- 1.4 mmHg systolic, 74.2 +/- 0.9 mmHg diastolic). Correlation coefficients were r = 0.713 for systolic and r = 0.683 for diastolic values, with significant variance of individual values. In direct comparison of the two methods immediately after ergometry the differences were even greater (57 mmHg systolic, 32 mmHg diastolic). Significantly lower digital pressures at the finger were noted in comparison with direct blood-pressure measurements after punction of the femoral artery. Because of significant differences of blood-pressure measurements compared to the Riva-Rocci method, the digital measurement with the HEM-812F device (Omron) can not be generally recommended.
