Why the study?

Does a wrist cuff oscillometric blood pressure device (OMRON R3) accurately measure blood pressure compared to intraarterial and mercury manometer measurements in patients undergoing cardiac catheterization?

Population

100 consecutive patients undergoing cardiac catheterization

Comparison

Wrist cuff oscillometric blood pressure… vs Intraarterial measurement and arm cuff mercury…

Design

Implication

Wrist cuff may offer reliable readings in catheterization; leaves open routine adoption versus mercury manometer.

Structured PICO

Does a wrist cuff oscillometric blood pressure device (OMRON R3) accurately measure blood pressure compared to intraarterial and mercury manometer measurements in patients undergoing cardiac catheterization?

P
Population
100 consecutive patients undergoing cardiac catheterization
I
Intervention
Wrist cuff oscillometric blood pressure measurement device (OMRON R3)
C
Comparator
Intraarterial (axillary artery) measurement and arm cuff mercury manometer
O
Outcome
Accuracy of systolic and diastolic blood pressure measurements compared to intraarterial valuessurrogate

The wrist cuff oscillometric device measures arterial blood pressure with high accuracy and reproducibility, showing better correlation with intraarterial diastolic pressure than a mercury manometer.
