Noninvasive Measurement of Central Vascular Pressures With Arterial Tonometry: Clinical Revival of the Pulse Pressure Waveform?

摘要: The arterial pulse has historically been an essential source of information in the clinical assessment health. With current sphygmomanometric and oscillometric devices, only peak trough peripheral waveform are clinically used. Several limitations exist with blood pressure. First, central aortic pressure is a better predictor cardiovascular outcome than Second, peripherally obtained does not accurately reflect because amplification. Lastly, antihypertensive medications have differing effects on pressures despite similar reductions brachial Applanation tonometry can overcome by determining shape from radial artery. Waveform analysis indicates systolic diastolic but also determines influence wave reflection waveform. It serve as useful adjunct to measurements initiating monitoring hypertensive treatment, observing hemodynamic atherosclerotic risk factors, predicting outcomes events. Radial artery applanation noninvasive, reproducible, affordable technology that be used conjunction guide patient management. Keywords for PubMed search were tonometry, artery, pressure, risk, pulse. Articles published January 1, 1995, July 2009, included review if they measured using tonometry.
