From: Arterial blood pressure monitoring in overweight critically ill patients: invasive or noninvasive?
Agreement between auscultatory and oscillometric, and intra-arterial blood pressure measurements. Shown are graphs for the (a) auscultatory method and (b) oscillometric method. The thicker line represents mean bias, and the thinner lines represent upper and lower limits of agreement. Squares are diastolic blood pressure measurement, diamonds are mean arterial blood pressure measurements, and circles are systolic blood pressure measurements. P < 0.001 between methods. IABP, intra-arterial blood pressure; NIBP, noninvasive blood pressure. a and b are not identified in the figure.
