Non-invasive oscillometric wrist and upper arm blood pressure measurements compared with invasive values.
In 100 patients invasive blood pressure (BP) measurements in the aortic arch were compared with oscillometric devices at the left upper arm (UA1, device: Hestia OZ 80) and at the left and right wrists (Wl, Wr, device: NAiS Blood Pressure Watch). BPs/BPd at Wl were on average 4.3/6.0 mmHg higher than aortic BP with a relative high variability. Difference between Wls and Aos more than +/- 20 mmHg in 16% of patients between Wld and Aod more than +/- 20 mmHg in 5% of patients. Within the limits of +/- 10 mmHg, we found 56% of the systolic and 74% of the diastolic wrist values compared to the aorta. The automatic oscillometric BP measurement at the wrist is a useful method for BP self-measurement, but should be compared with upper arm values before recommending it (difference < +/- 10 mmHg) in the individual case.
