Abstract: Devices and methods for multi-parameter hemodynamic monitoring are provided. Determining a cardiac output of a patient using a cuff device includes measuring a cuff pressure waveform of a subject during inflation and/or deflation of the cuff device, computing systolic and diastolic blood pressure from the cuff pressure waveform using the cuff device, constructing a blood pressure waveform from the systolic and diastolic blood pressure and cuff pressure waveform using the cuff device, computing brachial artery compliance from the cuff pressure waveform, and computing the cardiac output from the blood pressure waveform and/or brachial artery compliance using the cuff device.

Abstract: Devices and methods for determining blood pressures are provided. In one example, a device for determining blood pressure of a subject includes a camera configured to measure a finger photo-plethysmography (PPG) waveform, an accelerometer configured to measure a vertical height of the device relative to a heart of a subject, an output device configured to guide the subject to raise a hand to vary the transmural pressure of an artery while maintaining a finger pressure on the camera, and a processor configured to compute pulse pressure of the subject from the finger PPG waveform and the vertical height, and display the pulse pressure on the screen.
