Anesthesia Technician Practice Exam

What is a standard practice for calibrating FIO2 monitors before patient use?

1. Calibrated at least 24 hours prior

2. Calibrated in the operating room only

3. No calibration is required

4. Calibrated hourly

The correct answer is: Calibrated at least 24 hours prior

Calibrating FIO2 monitors at least 24 hours prior to patient use is essential for ensuring the accuracy and reliability of the measurements during anesthesia procedures. This standard practice allows ample time for any necessary adjustments or repairs to be made before the monitor is employed for patient care. Frequent calibration helps to verify that the monitor reflects true inspired oxygen concentrations, which is crucial for patient safety and optimal anesthesia management. Ensuring proper calibration 24 hours ahead ensures that the equipment has been tested in a stable environment, thus providing confidence in its performance when monitoring the patient during the procedure. Calibrating in the operating room specifically does not guarantee that there is sufficient time for the needed adjustments to be completed effectively; therefore, this wouldn't be considered standard practice. The tier of "no calibration required" does not apply since monitors need routine checks to confirm their accuracy. Additionally, calibrating hourly may overburden the workflow and is typically not necessary unless the monitor is being used in particularly volatile environments. Thus, calibrating 24 hours prior balances readiness with thorough verification of monitor functionality.
