A comparative study of measurement of arterial blood pressure using HEM-802F and arterial cannulation.
Finger arterial blood pressures determined by a newly developed sphygmomanometer, HEM-802F, were compared with arterial pressure obtained from direct measurement of the radial artery. An excellent correlation was found between the two methods (systolic: r = 0.93, diastolic: r = 0.91), although there was a large variability among individual subjects. The range of differences between them are from +32 to -13 mmHg for systolic and +15 to -25 mmHg for diastolic blood pressure measurement. HEM-802F underestimated systolic pressure (-4.0 mmHg) and overestimated diastolic pressure (+6.7 mmHg), compared with intra-arterial readings. The HEM-802F was useful for the non-invasive arterial pressure monitoring during general anesthesia.
