What is Hemodynamic Monitoring? - CORRECT ANSWERS Measurement of pressure, flow and
oxygenation within the cardiovascular system.
What are values that are measured in the ICU with Hemodynamic Monitoring? - CORRECT ANSWERS
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? - CORRECT ANSWERS The volume of blood in liters pumped by the
heart in 1 minute.
What is the Stroke Volume? - CORRECT ANSWERS The volume ejected with each heartbeat.
What determines Blood Pressure? - CORRECT ANSWERS CO and the forces opposing blood
flow.
What determines SV? - CORRECT ANSWERS Preload, afterload, and contractility.
What is Preload? - CORRECT ANSWERS Volume within the ventricle at the end of diastole.
What does PAWP reflect? - CORRECT ANSWERS 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? - CORRECT ANSWERS 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? - CORRECT ANSWERS Refers to the forces opposing ventricular ejection.
What does the Afterload include? - CORRECT ANSWERS The systemic arterial pressure, the
resistance offered by the aortic valve, and the mass and density of the blood to be moved.
What is Systemic Vascular Resistance? - CORRECT ANSWERS The resistance of the systemic
vascular bed.
What is Pulmonary Vascular Resistance? - CORRECT ANSWERS The resistance of the
pulmonary vascular bed.
What is Contractility? - CORRECT ANSWERS Describes the strength of contraction.
What are examples of positive inotropes? - CORRECT ANSWERS Epinephrine, norepinephrine
(Levophed), isoproterenol (Isuprel), dopamine (Intropin), dobutamine (Dobutrex), digitalis-like drugs,
calcium, and milrinone.
What category of drugs increase contractility? - CORRECT ANSWERS Positive Inotropes.
What category of drugs decrease contractility? - CORRECT ANSWERS Negative Inotropes.
What are examples of negative inotropes? - CORRECT ANSWERS Drugs (e.g., alcohol, calcium
channel blockers, B-adrenergic blockers,) and clinical conditions (e.g., acidosis).
