benefits of IABP - increased coronary artery perfusion decreased O2 demand increased O2 supply decreased afterload Pt getting IABP. Hour after return from Cath lab, pt has had minimal UOP. What would be most appropriate action? A. get CXR to verify catheter placement B. give fluid bolus C. administer furosemide D. decreased frequency to 1:2 - A. get CXR to verify catheter placement Cardiogenic shock: A. BP 96/54, CI 1.8, PAP 54/26, PAOP 10 B. BP 84/52, CI 1.9, PAP 32/18, PAOP 12 C. BP 82/48, CI 1.8, PAP 48/28, PAOP 18 D. BP 86/46, CI 2.0, PAP 28/14, PAOP 12 - C. BP 82/48, CI 1.8, PAP 48/28, PAOP 18 Following anterior wall MI, pt develops dysfunction of papillary muscle of mitral valve. There are large V waves on PAOP waveform. What is likely the cause? A. aortic regurg B. acute pulmonic regurg C. acute tricuspid regurg D. acute mitral regurg - D. acute mitral regurg Type of shock: cardiogenicCO/CI: Preload (CVP/PAOP) Afterload (SVR) ScvO2: Treatment: - Type of shock: cardiogenic CO/CI: decreased Preload (CVP/PAOP): increased Afterload (SVR): increased ScvO2: decreased (delivery issue) Treatment: +inotropes, after load reduction, pressors Type of shock: hypovolemic/hemorrhagic CO/CI: Preload (CVP/PAOP) Afterload (SVR) ScvO2: Treatment: - Type of shock: hypovolemic/hemorrhagic CO/CI: decreased Preload (CVP/PAOP): decreased Afterload (SVR): increased ScvO2: decreased Treatment: fluids Type of shock: distributive CO/CI: Preload (CVP/PAOP) Afterload (SVR) ScvO2: Treatment: - Type of shock: distributiveCO/CI: increased (hyper dynamic) Preload (CVP/PAOP): decreased Afterload (SVR): decreased ScvO2: decreased Treatment: fluids, pressers, inotropes Type of shock: obstructive CO/CI: Preload (CVP/PAOP) Afterload (SVR) ScvO2: Treatment: - Type of shock: obstructive CO/CI: decreased Preload (CVP/PAOP): increased Afterload (SVR): increased ScvO2: decreased Treatment: pericardiocentesis IABP position - 2nd to 3rd ICS, 1-2 cm distal to SCA below SCA, but above renal artery what to watch with IABP - urine output! palpate left radial pulse Dicrotic notch on arterial waveform represents: A. opening of pulmonic valveB. opening of tricuspid valve C. closure of aortic valve D. closure of mitral valve - C. closure of aortic valve IABP counterpulsation - want balloon to inflate during - DIASTOLE, pushes blood back into coronary arteries coronary arteries are perfused during - DIASTOLE IABP inflates - at onset of diastole at dicrotic notch IABP deflates - prior to systole
