Abstract
The present study compares two different methods for non-invasive beat -to-beat finger arterial blood pressure monitoring. The measurements u sing the volume clamp method (FINAPRES, Ohmeda, USA) were compared wit h measurements applying the differential oscillometric method (UT9201 device, University of Tartu). 13 healthy volunteers were studied at re st, during head-up tilt (HUT) and during deep breathing (DB) with a fi xed rate of 6 breaths/min. Blood pressure was recorded from adjacent f ingers of the right hand. 150 pairs of mean blood pressure values in e ach subject were included for statistical evaluation. No systematic di fferences between the two methods were found. The difference between v alues (FINAPRES - UT9201) at rest was -1.1 mmHg (SD 5.5), during HUT 0 .5 mmHg (SD 6.9) and during DB -3.6 mmHg (SD 7.7). The insignificant d ifferences between the results obtained by the two independent methods allow us to conclude that both methods give reliable data on finger m ean arterial pressure.
