Which of the following represents the technique used to measure current changes that occur when oxygen is reduced?

Question

Quizplus · Accepted Answer

The PO₂ is determined by measuring current changes that occur as oxygen is reduced,hence the technique represents an amperometric measurement.The blood gas factor is a phenomenon due to the slow rate of oxygen diffusion in fluids (i.e.,oxygen consumed by an electrode is not replaced by oxygen from the blood).Measurements based on voltage changes are called potentiometric measurements.Tonometry is a measure of pressure and a method of quality control for arterial blood gas machines.
