Does a new photo-oscillometric method employing the delta-algorithm improve blood pressure measurement accuracy compared to the conventional auscultatory method in normotensive and hypertensive subjects?
A new photo-oscillometric method using the delta-algorithm provides more accurate blood pressure measurements than the conventional auscultatory method when compared to direct intra-arterial measurement.
