What is Hemodynamic Monitoring? - Measurement of pressure, flow and oxygenation within the cardiovascular system. What are values that are measured in the ICU with Hemodynamic Monitoring? - Systemic and Pulmonary arterial pressures, central venous pressures (CVP), pulmonary artery wedge pressure (PAWP), CO/CI, SV/SV index (SVI) and O2 saturation of the hemoglobin of arterial blood (SaO2) and mixed venous oxygen saturation (SvO2). What is Cardiac Output? - The volume of blood in liters pumped by the heart in 1 minute. What is the Stroke Volume? - The volume ejected with each heartbeat. What determines Blood Pressure? - CO and the forces opposing blood flow. What determines SV? - Preload, afterload, and contractility. What is Preload? - Volume within the ventricle at the end of diastole. What does PAWP reflect? - A measurement of pulmonary capillary pressure that reflects left ventricular end diastolic pressure under normal conditions (i.e., when there is no mitral valve dysfunction, intracardiac defect, or dysrhythmia). What is CVP? - Measured in the right atrium, or in the vena cava close to the heart, is the right ventricular preload or right ventricular end-diastolic pressure when there is no tricuspid valve dysfunction, intracardiac defect or dysrhythmia. What is Afterload? - Refers to the forces opposing ventricular ejection.
