What is the standard reference for validating BP devices?

• A. ISO 9001
• B. ANSI/AAMI/ISO 81060-2
• C. FDA 510(k)
• D. IEC 60601

Answer: (B)

This question tests recognizing the standard used to validate blood pressure devices. ANSI/AAMI/ISO 81060-2 is the joint protocol that defines how to test and prove the accuracy of noninvasive BP monitors, setting the procedures, reference method, and acceptance criteria needed to determine if a device’s readings are clinically acceptable.

It provides concrete guidance on how measurements should be performed (including appropriate cuff sizes, arm position, and subject variety), which reference method to compare against, and the statistical criteria for accuracy (how close the device readings must be to the reference and how much variability is allowed). Because this standard is internationally recognized and routinely used by manufacturers and laboratories, following it ensures consistency and reliability across devices and settings.

ISO 9001 is about quality management systems, not a specific validation method for BP measurements. FDA 510(k) is a regulatory clearance pathway, not a validation protocol. IEC 60601 covers electrical safety and essential performance of medical electrical equipment, not the clinical accuracy validation of BP devices.
