Implication

Cuff diastolic BP may inaccurately reflect intra-arterial values; challenges reliance on noninvasive measurements in hypertension trials.

Key Points

To compare arterial blood pressure measurements obtained via intra-arterial and cuff methods.
Analysis of discrepancies in blood pressure measurements using both methods.
Evaluation of the effect of arm circumference on cuff measurements.
Comparison of systolic and diastolic pressures between the two techniques.
Good agreement reported for systolic pressures between intra-arterial and cuff methods.
Discrepancy exists in identifying true diastolic pressure between phases 4 (muffling) and 5 (disappearance).
Arm circumference influences cuff measurement accuracy.

Intervention

Intra-arterial blood pressure measurement

Comparator

Cuff and sphygmomanometer blood pressure measurement

Outcome

Agreement between intra-arterial and cuff blood pressure valuessurrogate

Highlights the ongoing debate regarding the accuracy of cuff-based blood pressure measurements compared to intra-arterial methods, particularly for determining true diastolic pressure.
