To compare estimates of left ventricular (LV) end-systolic elastance created by inferior vena caval (IVC) occlusion with those by apneic continuous positive airway pressure (CPAP). Prospective interventional study in a university large animal research laboratory. Sixteen intact, pentobarbital-anesthetized mongrel male dogs. Insertion of LV conductance and pressure catheters, then during apnea sequentially performed IVC occlusion and CPAP of 5, 10, and 15 mmHg for 10 s, each interspersed by… CONTINUE READING
