How can the concentration of anesthetic gases be monitored during a procedure?

• A. Using a thermometer
• B. Using a gas analyzer or capnometer
• C. Using visual inspection
• D. Using a pulse oximeter

Answer: (B)

Monitoring the concentration of anesthetic gases during a procedure is crucial for ensuring patient safety and effective anesthesia management. A gas analyzer or capnometer is specifically designed to measure the concentration of gases in the inhaled and exhaled breath of the patient. This device analyzes the gas composition, providing real-time feedback on the levels of anesthetic agents, carbon dioxide, and other gases present.

This capability is essential in maintaining the appropriate anesthesia depth and adjusting dosages as needed throughout the procedure. A gas analyzer can help detect any undesired changes in gas concentrations, allowing for prompt interventions if necessary, which is vital for patient safety and successful outcomes in anesthesia management.

In contrast, other options do not provide the necessary measurements for anesthetic gas concentrations. A thermometer measures temperature but not gas concentrations; visual inspection alone is not reliable for gauging gas levels accurately; and a pulse oximeter monitors oxygen saturation in the blood but does not analyze the anesthetic gas concentrations or carbon dioxide levels.
