Evaluation of Sensifree's Alpha Sensor Signal Morphology Compared to Arterial Line and PPG Signal Morphologies

RF based, wrist mounted sensor, that acquires a high fidelity signal originating at the radial artery, and constructs a pressure waveform

Invasive monitoring of blood pressure via catheterization of the radial artery, displaying a continuous pressure waveform

PPG based, fingertip mounted sensor, that measures the oxygen level (oxygen saturation) of the blood and generates a waveform
