In this episode, we review pulmonary artery (Swan-Ganz) catheterization. What are indications and contraindications to pulmonary artery catheter placement? What variables make up the oxygen content equation and oxygen delivery equation? What is the difference between mixed venous oxygen saturation (SvO2) and central venous oxygen saturation (ScvO2)? What conditions cause elevated or depressed SvO2? What conditions cause elevated and depressed pulmonary vascular resistance (PVR) and systemic vascular resistance (SVR)? What are the drawbacks and advantages of Fick cardiac output versus thermodilution cardiac output? What is the pulmonary artery pressure index (PAPi) and cardiac power output (CPO), and how can PAPi and CPO be used to make decisions in cardiogenic shock? Is left ventricular end-diastolic pressure (LVEDP) synonymous with as wedge pressure? Tune in for answers to these questions.
