متن کاملClinical Assessment of Central Blood Pressure
Central aortic blood pressure (CBP) is increasingly considered a better cardiovascular prognostic marker than conventional cuff brachial blood pressure. Because CBP cannot be directly measured noninvasively, it has to be estimated from peripheral pressure pulses. To assess estimated CBP appropriately, the accuracy and features of the estimation method should be considered. The aim of this revie...
متن کاملCentral Blood Pressure/Aortic Stiffness Validation of a Brachial Cuff-Based Method for Estimating Central Systolic Blood Pressure
The prognostic value of central systolic blood pressure has been established recently. At present, its noninvasive assessment is limited by the need of dedicated equipment and trained operators. Moreover, ambulatory and home blood pressure monitoring of central pressures are not feasible. An algorithm enabling conventional automated oscillometric blood pressure monitors to assess central systol...
متن کاملPressure wave reflection assessed from the peripheral pulse: is a transfer function necessary?
Synthesis of the aortic pressure waveform by application of a transfer function to the radial pulse allows the estimation of aortic systolic blood pressure and aortic augmentation index, an index of pressure wave reflection derived from the early systolic component of the waveform. The accuracy of this approach for determining the aortic augmentation index has been questioned, however, and it m...
متن کاملValidation of the transfer function technique for generating central from peripheral upper limb pressure waveform.
Central aortic pressure waveforms can be calculated from the radial artery pressure waveform using a generalized transfer function to correct for pressure wave distortion in the upper limb. Although validated to standards conventionally applied, reservations are still expressed on use of this process, because of the relatively small number of patients from whom appropriate invasive data were ob...
