Functional Hemodynamic Monitoring With a Wireless Ultrasound Patch

In this Emerging Technology Review, a novel, wireless, wearable Doppler ultrasound patch is described as tool for resuscitation. The device designed, foremost, functional hemodynamic monitor—a simple, fast, and consistent method measuring change with preload variation. More generally, monitoring paradigm that helps predict stroke volume response to additional intravenous volume. Because of the left ventricular outflow tract noninvasively measures in realtime, it increasingly deployed purpose. Nevertheless, manner cumbersome, especially when repeat assessments are needed. Accordingly, peripheral arteries have been studied various from common carotid artery signal act windows ventricle. Yet, handheld susceptible human measurement error statistical limitations inadequate beat sample size. Therefore, capable continuous assessment minimizes inconsistencies smooths inherent physiologic variation by sampling many more cardiac cycles. Reaffirming clinical studies, tracks immediate SV excellent accuracy healthy volunteers altered maneuvers. also follows jugular venous Doppler, which qualitatively trends right atrial pressure. With further research application artificial intelligence, modalities new technology manifold.
