How to validate semi-automatic blood pressure monitors yearly?

Introduction

It is recommended to validate semi-automated blood pressure monitors annually e.g., by using a patient simulator.

ANSI-American National Standards Institute accepts that semi-automatic blood pressure monitors (NIBP) have an average maximum deviation up to ±5mmHg and a SD less than

±8mmHg

Aim

This study aimed to investigate the average deviation of the systolic and diastolic blood

pressure on different models of NIBP with two newly calibrated simulators from Rigel and

Fluke to investigate whether the

measurements were consistent with ANSI- American National Standards Institute

recommendations.

Conclusion

This study showed that the number of monitors deviating more than recommended by the American National Standards Institute depended on which of the two simulators that had been utilized.

Using the Rigel simulator all recently calibrated A&D Medical monitors and some of the new Microlife monitors deviated more than 5 mmHg, while almost all new Microlife monitors deviated more than 5 mmHg when tested with Fluke.

Therefore, semi-automated blood pressure monitors’ average deviation of the systolic and diastolic blood pressure from the test pressure depends on the utilized simulator

Method

Four newly calibrated A&D Medical UA-852

monitors and 46 new Microlife monitors (17 BP A3L comfort, 19 BP A3plus 10 BP A2basic)

were tested on two calibrated simulators (Rigel UNI-SIM Vital Sign Simulator and Fluke ProSim 8) capable of simulating arm blood pressure.

The monitors were tested at five different

systolic/diastolic blood pressure [80/40 -220/

180mmHg] pulse 80 using the belonging adult cuff. All pressures were measured three times , and the mean pressure, average SD and

average deviation from test pressure of each monitor were calculated.
