To derive blood pressure, the device measures the time-of-flight between ultrasound echoes reflected from the anterior and ...

Over the last decade a number of studies have been reported that have used heart–lung interactions during mechanical ventilation to assess fluid responsiveness. Specifically, the pulse pressure ...

The new device uses sound waves to gather blood pressure data from blood vessels, monitoring the response with ultrasound. The new technique, called resonance sonomanometry, holds the promise to ...

Systolic, diastolic, and mean arterial pressures (MAP) are the 3 BP values typically reported; to interpret a BP reading, all 3 must be evaluated. Systolic and diastolic BP are the pressures at the ...

Illustration and principle of the subcutaneous and continuous BP monitoring by PMUTs in an ambulatory sheep. a The PMUT device is implanted subcutaneously near the sheep’s femoral artery to emit ...

A concept design showing what the team envisions as final products using the resonance sonomanometry blood pressure method. The device on the upper arm measures from the brachial artery and the ...
