COMPARISON OF OSCILLOMETRIC AND INTRAARTERIAL BLOOD-PRESSURE AND PULSE MEASUREMENT

Non-invasive oscillometric blood pressure and pulse measured by an Omron HEM-703CP monitor were compared with arterial values obtained from direct measurements of the radial artery. An excellent correlation and agreement was found between the two methods (systolic r = 0.99; diastolic r = 0.97; pulse r = 0.99), although (here was some variability among individual subjects. The range of difference between them was 0 to 10 mmHg for systolic and - 6 to + 5 mmHg for diastolic pressures. When tested on the bench wing the Metron QA-1280 non-invasive blood pressure analyser the HEM-703CP monitor rarely exhibited errors exceeding 2-3 mmHg over a measurement range of 50-200 mmHg.
