The collective resistance of all the vessels in the prophetical circulation. Hemodynamics or blood flow is affected by what factors? Pressure, resistance, flow, radius, blood viscosity, compliance, wall tension What is cardiac output? The efficiency of the heart's pump is measured by the cardiac output. The cardiac output (CO) is the amount of blood the heart pumps each minute. It is the product of the stroke volume (SV) and the heart rate (HR). CO = SV x HR. What is preload? Preload is the end-diastolic pressure when the ventricle has been filled and represents the volume work of the heart. What is afterload? Afterload is the pressure the heart must generate to move blood into the aorta. What is cardiac contractility? Cardiac contractility is the ability of the heart to change its force of contraction without changing its resting (diastolic) length. What is an inotrope? an agent that alters the force or energy of muscular contractions What is mean arterial pressure? An inotropic influence is one that increases the strength of the muscular contraction. What is thrombocytosis? Thrombocytosis is defined as an elevated platelet count above 450,000/µL. [Show More]
