Dynamic Arterial Elastance Measured by Uncalibrated Pulse Contour Analysis Predicts Arterial Pressure Response to a Decrease in Norepinephrine

Patients with vasoplegic syndrome for whom the intensive care physician planned to decrease the norepinephrine dosage were included. Hemodynamic and uncalibrated pulse contour analysis (Volume view, FloTrac, Edwards Lifescience, Irvine) values were obtained before and after decreasing the norepineprhine dosage. Responders were defined by a \>10% decrease in mean arterial pressure (MAP).
