BTC BTC Biomedical Equipment Calibration & Testing 1

Question 1

What is the primary purpose of calibrating biomedical equipment?

Accepted Answer

To ensure measurements are accurate and traceable to national standards

Answer

Calibration ensures that a device's measurements are accurate and traceable to national or international standards such as NIST.

Question 2

Which organization provides the national measurement standards used as the reference for biomedical equipment calibration in the US?

Accepted Answer

NIST (National Institute of Standards and Technology)

Answer

NIST provides the national measurement standards that serve as the traceability reference for calibration activities in the US.

Question 3

How often should a biomedical technician perform a performance verification on a patient monitor?

Accepted Answer

According to the manufacturer's recommended schedule and facility PM policy

Answer

Performance verification intervals are set by the manufacturer's specifications and the facility's preventive maintenance policy.

Question 4

What does 'as-found' data mean in a calibration record?

Accepted Answer

The measurement values recorded before any adjustments during a calibration

Answer

As-found data captures the device's performance state before any corrections, providing a historical baseline for trend analysis.

Question 5

Which instrument is most commonly used to calibrate the output accuracy of an infusion pump?

Accepted Answer

Graduated cylinder and stopwatch (or electronic flow analyzer)

Answer

Infusion pump flow rate accuracy is verified using a graduated cylinder and stopwatch or a dedicated electronic flow analyzer.
