Near-infrared spectroscopy (NIRS)-monitored cerebral oxygenation using the regional cerebral saturation (rScO 2) and the cerebral fractional tissue oxygen extraction (cFTOE), derived from rScO 2 and ...

A PaO2 test measures partial pressure of oxygen, or PaO2—the oxygen pressure in arterial blood. The PaO2 reflects how well oxygen is able to move from the lungs to the blood. It is often altered by ...
