Open Access Abstract Introduction Blood pressure measurements frequently guide management in critical care. Direct readings commonly from a major artery are considered to be the gold standard. Because arterial cannulation is associated with risks alternative noninvasive blood pressure NIBP measurements are routinely used. However the accuracy of NIBP determinations in overweight patients in the outpatient setting is variable and little is known about critically ill patients. This prospective observational study was performed to compare direct intraarterial blood pressure IABP with NIBP measurements obtained using auscultatory and oscillometric methods in overweight patients admitted to our medical intensive care unit. Method Adult critically ill patients with a body mass index BMI of 25 kg m2 or greater and a functional arterial line assessed using the rapid flush test were enrolled in the study. IABP measurements were compared with those obtained noninvasively. A calibrated aneroid manometer auscultatory technique with arm cuffs compatible with arm sizes and a NIBP
