Noninvasive continuous blood pressure control by pulse wave velocity
Abstract:
A comparison of arterial pulse wave velocity (PWV) detected by ultrasonic Doppler probes and invasive blood pressure data was performed. For accurate assessment of PWV beat-to-beat detection of the pulse transit time (PTT) was performed by means of two 8 Mhz ultrasonic Doppler probes placed externally over the right brachial resp. radial artery, as a reference the continuous invasive blood pressure (IAP) of the contralateral radial artery was collected. Comparing the PWV associated blood pressure (APPWV) and IAP yielded a correlation coefficient of r = 0.86, and Bland-Altman plotting proved 95% (+/- 2 SEM) of APPWV values to differ within +/- 10 mm Hg from IAP. With this clinical study we found that beat-to-beat PWV measurement noninvasively, continuously and reliably monitors arterial blood pressure especially with respect to rapid blood pressure changes.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
