Continuous Blood Pressure and Waveform Measurements Comparison Between Invasive Arterial Line and PPG Sensor

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

A blood pressure cuff is used to measure blood pressure. The cuff has an inflatable rubber bladder that is typically fastened around the arm. A pressure meter indicates the cuff's pressure.
