Carotid Artery Corrected Flow Time Measured by Wearable Doppler Ultrasound Detects Stroke Volume Change Measured by Transesophageal Echocardiography After Coronary Artery Bypass Grafting Open
Background: As a measure of preload responsiveness (PR), change in carotid artery corrected flow time (ccFTΔ) is a surrogate for change in stroke volume (SVΔ). However, the optimal threshold and accuracy of ccFTΔ to detect SVΔ are inconsis…

Defining the physiological bounds of left ventricular ejection time with a wireless, wearable ultrasound: An analysis of over 137,000 cardiac cycles Open
Background Flow time (FT) or the left ventricular ejection time (LVET) is the duration of mechanical systole, when the aortic valve is open and ejecting blood. LVET can be measured in the common carotid artery from the time of the systolic…

Inferior Vena Caval Measures Do Not Correlate with Carotid Artery Corrected Flow Time Change Measured Using a Wireless Doppler Patch in Healthy Volunteers Open
(1) Background: The inspiratory collapse of the inferior vena cava (IVC), a non-invasive surrogate for right atrial pressure, is often used to predict whether a patient will augment stroke volume (SV) in response to a preload challenge. Th…

The Correlation between Carotid Artery Corrected Flow Time and Velocity Time Integral during Central Blood Volume Loss and Resuscitation Open
Background: Doppler ultrasound of the common carotid artery is used to infer central hemodynamics. For example, change in the common carotid artery corrected flow time (ccFT) and velocity time integral (VTI) are proposed surrogates of chan…

Detecting the Change in Total Circulatory Flow with a Wireless, Wearable Doppler Ultrasound Patch: A Pilot Study Open
OBJECTIVE: Measuring fluid responsiveness is important in the management of critically ill patients, with a 10–15% change in cardiac output typically being used to indicate “fluid responsiveness.” Ideally, these changes would be measured n…

Combined frequency domain photoacoustic and ultrasound imaging for intravascular applications Open
Intravascular photoacoustic (IVPA) imaging has the potential to characterize lipid-rich structures based on the optical absorption contrast of tissues. In this study, we explore frequency domain photoacoustics (FDPA) for intravascular appl…
