A novel, hands-free ultrasound patch for continuous monitoring of quantitative Doppler in the carotid artery

Abstract Quantitative Doppler ultrasound of the carotid artery has been proposed as an instantaneous surrogate for monitoring rapid changes in left ventricular output. Tracking immediate changes in the arterial Doppler spectrogram has value in acute care settings such as the emergency department, op...
