Comparative StudyEstimating central systolic blood pressure during oscillometric determination of blood pressure: proof of concept and validation by comparison with intra-aortic pressure recording and arterial tonometry.
Central systolic blood pressure is usually estimated by transformation of a peripheral arterial waveform obtained by tonometry and calibrated from conventional measurements of brachial artery blood pressure from a brachial cuff using the oscillometric principle. We investigated whether central blood pressure could be obtained directly from a brachial cuff waveform, allowing the measurement of central blood pressure to be incorporated into the standard oscillometric determination of blood pressure. ⋯ Central systolic blood pressure can be obtained from a brachial cuff waveform with an accuracy comparable to that of a tonometer.
