Fig. 2From: Association of infraclavicular axillary vein diameter and collapsibility index with general anesthesia-induced hypotension in elderly patients undergoing gastrointestinal surgery: an observational studyScatter plots showing AXV-CI and IVC-CI in relation to the decrease in mean arterial blood pressure. (AXV-CI, collapsibility index of the axillary vein; MAP, mean arterial blood pressure; IVC-CI, collapsibility index of the inferior vena cava. Dashed line is trend line)Back to article page
