Assessment of sequential same arm agreement of blood pressure measurements by a CVProfilor™ DO–2020 versus a Baumanometer® mercury sphygmomanometer
Key result
The CVProfilor DO-2020 oscillometric device showed reasonable agreement with a mercury sphygmomanometer, with a mean difference in systolic blood pressure of -3.2 +/- 6.9 mmHg.
Why the study?
Does the CVProfilor DO-2020 oscillometric device provide accurate blood pressure measurements compared to a mercury sphygmomanometer in normotensive and hypertensive subjects?
Population
230 normotensive and hypertensive subjects, 57% females, 51% Caucasians, and 33% African Americans.
Comparison
CVProfilor DO-2020 Cardiovascular Profiling System vs Baumanometer mercury sphygmomanometer

Prisant et al. (2001) conducted a cross-sectional in Normotension and hypertension (n=230). CVProfilor DO-2020 Cardiovascular Profiling System vs. Baumanometer mercury sphygmomanometer was evaluated on Mean difference in systolic blood pressure (MD -3.2 mmHg). The CVProfilor DO-2020 oscillometric device showed reasonable agreement with a mercury sphygmomanometer, with a mean difference in systolic blood pressure of -3.2 +/- 6.9 mmHg.
