Example of the dose-response of negative end-expiratory pressure on indices of left ventricular filling and ejection. The top panel displays changes in thoracic fluid content and stroke volume measured by bioreactance. The bottom panel shows the change in measured and transmural left-ventricular end diastolic pressure (EDP) as the expiratory pressure decreases. Ventricular pressures were normalized to their baseline values. This demonstrates that while measured EDP declined slightly, transmural EDP increased nearly sixfold
