Implication

May support semi-automated BP devices in routine practice; leaves open need for broader prospective validation.

Key Points

To evaluate the measurement accuracy and clinical suitability of the A&D UA-751 semi-automated cuff-oscillometric sphygmomanometer in comparison with a standard Hawksley random-zero mercury sphygmomanometer.
Obtained duplicate, simultaneous single-arm blood pressure measurements across 200 subjects with blood pressure ranging from 92–221/51–121 mmHg.
Compared readings taken by three observers using a Hawksley random-zero mercury sphygmomanometer against recordings from two A&D UA-751 devices.
Achieved acceptable agreement per Association for the Advancement of Medical Instrumentation criteria, with mean systolic differences ranging from -0.9 to 1.4 mmHg (SD 4.6–9.8 mmHg).
Demonstrated mean diastolic differences ranging from -0.6 to 1.3 mmHg (SD 2.9–5.1 mmHg), despite notable discrepancies observed in individual subjects.

Structured PICO

Does the A&D UA-751 semi-automated cuff-oscillometric sphygmomanometer provide accurate blood pressure measurements compared to a conventional mercury sphygmomanometer?

Population

200 subjects having blood pressure in the ranges 92-221/51-121 mmHg

Intervention

Blood pressure measurement using the A&D UA-751 semi-automated cuff-oscillometric sphygmomanometer

Comparator

Blood pressure measurement using a conventional Hawksley random-zero mercury sphygmomanometer

Outcome

Agreement between blood pressure recordings (range of differences)surrogate

The A&D UA-751 semi-automated sphygmomanometer provides acceptable blood pressure measurements compared to a conventional mercury device, making it suitable for routine clinical and home use.

Limitations

Sizeable discrepancies in individual subjects
