From: Common carotid artery diameter responds to intravenous volume expansion: an ultrasound observation
Effect of intravascular volume expansion on CCA geometry, MAP and PPV. CCA diameter increases with intravenous administration of crystalloid infusion solution (7 ml/kg BW) (left). MAP increases with intravenous administration of infusion solution (middle). PPV is reduced upon intravenous administration of fluid (right). CCA common carotid artery, MAP mean arterial pressure, PPV pulse pressure variation. Data are given as median with percentile 25–75. Wilcoxon matched pairs test, *p < 0.05; ***p < 0.001. n = 20
