Question

Quizplus · Accepted Answer

A pulse oximeter is a noninvasive device that uses light waves to measure oxygen saturation (SpO₂) in the bloodstream. Capnography measures exhaled carbon dioxide levels, a sphygmomanometer measures blood pressure, and an end-tidal CO₂ meter measures the amount of carbon dioxide present at the end of exhalation.
