Does non-invasive oscillometric blood pressure measurement using the Omron HEM-703CP monitor agree with direct radial artery measurements?
The Omron HEM-703CP monitor provides non-invasive blood pressure and pulse measurements that correlate excellently with direct radial artery measurements.

Supports limited agreement of oscillometric BP with invasive measures; leaves open larger validation before clinical substitution.
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 there 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 using 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.
