Final answer:
Infrared monitors would not work for measuring oxygen concentration as oxygen does not have a specific absorption band in the infrared spectrum. Electrochemical, paramagnetic, and sidestream monitors can be used for this purpose.
Step-by-step explanation:
The type of monitor that would not work for monitoring the concentration of oxygen being delivered to a patient is C) Infrared. Oxygen does not absorb infrared light in a way that can be used to accurately measure its concentration. The monitors suitable for this purpose include:
- Electrochemical monitors, measure oxygen concentration through a chemical reaction that produces an electric current proportional to the concentration of oxygen.
- Paramagnetic monitors, exploit the paramagnetic properties of oxygen to measure its concentration.
- Sidestream monitors, analyze a sample of gas taken from the main flow to measure the oxygen concentration.
Each monitor has its unique way of measuring oxygen concentrations, but infrared technology is not among them when it comes to oxygen monitoring because it does not have a specific absorption band in the infrared spectrum that could be used for measurement purposes.
