Brief summary
for patients connected to VA ECMO due to cardiogenic shock, monitoring: 1. Cerebral Oximetry 2. ECMO Parameters ECMO blood flow (L/min) every 12 hours. Sweep gas flow Cannulation configuration 3. Pulmonary Artery Catheter Data and hemodynamics: Cardiac output / cardiac index, SvO₂, Central venous pressure (CVP). 4. other variables: P/F ratio, MAP, Heart rate, Arterial blood gases, hemoglobin, Lactate, Vasopressor / inotrope doses and Sedation score (RASS). 5. Echocardiography parameters: recorded every 12 hours. LV ejection fraction. LVOT VTi. LVED dimension. Aortic valve opening. 6. Follow-up data: * ECMO duration. * Need for oxygen therapy/mechanical ventilation. * ICU survival.
Detailed description
for patients connected to VA ECMO due to cardiogenic shock, monitoring: 1. Cerebral Oximetry Bilateral frontal sensors, rScO₂ recorded: at baseline (within 1 hour of ECMO initiation) then every 12 hours. 2. ECMO Parameters Pump speed (RPM) ECMO blood flow (L/min) every 12 hours. Sweep gas flow Cannulation configuration Arterial cannulation site 3. Pulmonary Artery Catheter Data and hemodynamics: Cardiac output / cardiac index every 12 hours. SvO₂. Central venous pressure (CVP) Mean pulmonary artery pressure. Pulmonary capillary wedge pressure. Systemic vascular resistance. 4. Echocardiography parameters: recorded every 12 hours. LV ejection fraction. LVOT VTi. LVED dimension. Aortic valve opening. 5. Other variables: P/F ratio. MAP. Heart rate. Arterial blood gases. Lactate. Hemoglobin. Vasopressor / inotrope doses. Sedation score (RASS). 6. Follow-up data: * ECMO duration. * Need for oxygen therapy/mechanical ventilation. * ICU survival.
