Why the study?

Does the Dinamap 1846SX automated blood pressure recorder provide comparable measurements to the Hawksley random zero sphygmomanometer in adults and children?

Key Points

This study aims to compare the Dinamap 1846SX automated blood pressure recorder with the Hawksley random zero sphygmomanometer under field conditions.
Two measurement comparisons were made within subjects: one with adults and one with children.
In adults, alternating pairs of measurements were taken, while children underwent one random measurement with each instrument.
Measurements were conducted over several months during epidemiological field surveys.
In adults, Dinamap measurements were higher by 8.1 mm Hg (95% CI 6.5 to 9.7 mm Hg).
In children, Dinamap measurements were higher by 8.3 mm Hg (95% CI 6.9 to 9.7 mm Hg).
Diastolic measurements were similar; Dinamap readings were higher at low diastolic pressures and Hawksley readings were higher at high diastolic pressures.

Answers are grounded in this paper and cite their sources.

Implication

The Dinamap 1846SX automated blood pressure recorder yields significantly higher systolic blood pressure readings compared to the Hawksley random zero sphygmomanometer, indicating they are not directly interchangeable in clinical or epidemiological settings.
