Noninvasive Techniques for Blood Pressure Measurement Are Not a Reliable Alternative to Direct Measurement: A Randomized Crossover Trial in ICU
Figure 2
Bland-Altman analysis of the agreement between systolic (SAP), diastolic (DAP), and mean (MAP) arterial pressure in comparisons between direct-invasive (IBP) and, respectively, auscultatory-aneroid (ABP) and oscillometric automated (OBP) methods. The dashed line represents the mean bias; the upper and lower limits of the box represent the 1.96 SD limits of agreement.
