With a new oscillometric method equipped with a transmittance infrared photoelectric plethysmograph, indirect systolic, and mean arterial pressures were measured in 12 normotensive and hypertensive subjects with systolic and mean arterial pressures ranging from 55 to 163 mmHg and from 95 to 200 mmHg, respectively. The pressure values obtained by this method were compared with direct measurements of the brachial intra-arterial pressure recorded simultaneously. A fairly good correlation between the pairs of simultaneous data from these two methods were obtained.
