Quiz # 1 Study Guide Pulmonary Artery Catheters (PA) (SWAN-GANZ) 1. Inserted in large vein (jugular, femoral, subclavian, brachial) 2. Threated through R-atria & R-ventricle 3. Into a branch of the pulmonary artery (PA) COMPONENTS of PA catheter:  Proximal Lumen: o May have 1 or 2 proximal ports o Sits in R-atrium or in R-atrium or R-ventricle (if there are 2 ports) o Measures R-atria pressure (CVP) & cardiac output (CO) o Infusion of IV fluids for CO determination o Obtain venous blood samples  Distal Lumen: o Sits in pulmonary artery o Obtains SvO2 sampling (60 – 80%) to evaluate O2 sat o Measures PAPs:  PA systolic (PAS) (15 – 28)  PA diastolic (PAD) (5 – 16)  Mean PA pressure  PA wedge pressure (PAWP) o NOT used for IV fluids or medications  Balloon Inflated Port: o Intermittently used to 1. Allow blood to “float” the catheter forward 2. Get PAWP pressure o Not left inflated o When not used, disinflate & lock  Thermistor Port: o Measures core temperature o Measures Cardiac Output by thermodilution method  Temperature changes from R-atrium to pulmonary artery after fluid injection
