Fig. 3From: Respiratory changes of the inferior vena cava diameter predict fluid responsiveness in spontaneously breathing patients with cardiac arrhythmiasLinear correlation of the delta of the inspiratory diameter of the inferior vena cava (∆iIVC) between standardized and spontaneous unstandardized breathing, and a the delta of inspiratory buccal pressure (∆Pinsp), and b the delta of diaphragmatic inspiratory excursion (∆DiaphExc) in responders. Linear correlation of ∆iIVC between standardized and spontaneous unstandardized breathing, and c ∆Pinsp, and d ∆DiaphExc in nonrespondersBack to article page
