During physiologic calibrations, technicians perform this to verify what?

• A. Assess the function of the computer keyboard
• B. Verify electrode response commands
• C. Assess the function of the electrical bed
• D. Verify the polarity of the ECG

Answer: (B)

The main idea is that physiologic calibrations are used to verify that the sensor inputs (the electrodes) respond correctly to the system’s commands. During calibration, the device sends test signals to each electrode channel and checks that the channel detects the response as expected. This confirms the electrode is properly connected, the signal path is intact, and the gain/impedance are within acceptable ranges so that real patient signals will be captured accurately. Other tasks like checking a keyboard, testing an electrical bed, or confirming ECG lead polarity address different aspects of safety or setup and are not what calibration is primarily validating.
