Which of the following statements are true concerning in vivo arterial blood gas analyzers?

Question

Quizplus · Accepted Answer

In vivo arterial blood gas monitors use optical sensors and fiberoptic technology for light transmission through the sensors.Polarographic electrodes are not used in vivo.In many cases,temperature corrections might be required because the sensor may be in a peripheral artery,where the measured temperature might not equal the patient's core temperature.Correlations may not be as good for PCO₂ and PO₂ as they are for pH and therefore may be less accurate than in vitro blood gas analyzers.
