Key result
Oscillometric blood pressure measurement underestimated invasive arterial blood pressure by a mean of 6.7 mm Hg in critically ill patients.
Why the study?
Does oscillometric blood pressure measurement accurately reflect invasive arterial blood pressure in critically ill patients across different cuff sizes and upper-arm circumferences?
Observational (n=38)
No
Does oscillometric blood pressure measurement accurately reflect invasive arterial blood pressure in critically ill patients across different cuff sizes and upper-arm circumferences?
Oscillometric blood pressure measurement significantly underestimates arterial blood pressure in critically ill patients, with a high proportion of measurements falling outside the clinically acceptable range.
Answers are grounded in this paper and cite their sources.
May warrant caution interpreting oscillometric BP in the ICU; leaves open cuff size or arm circumference effects on accuracy.

Bur et al. (2000) conducted an observational in Critically ill (n=38). Oscillometric blood pressure measurement vs. Invasive mean arterial blood pressure measurement was evaluated on Discrepancy between oscillometric and invasive mean arterial blood pressure measurement using recommended cuff size (MD -6.7, p=<.0001). Oscillometric blood pressure measurement underestimated invasive arterial blood pressure by a mean of 6.7 mm Hg in critically ill patients.
