…and the appropriate action differs fundamentally between these cases. Pressures in the heart and pulmonary circulation Flow, resistance and oxygen transport Formulas Mean arterial pressure…

…there is increased resistance in the aortic valve itself, due to the reduced area of the valvular orifice. Both aortic stenosis and hypertension result in…

…Induces arteriolar vasodilation without effects on venous circulation. The reduction in systemic vascular resistance (SVR) is rapid and may cause reflex sympathetic stimulation, including tachycardia…

…difficult to eject blood into the aorta. In the early stages of aortic stenosis, stroke volume becomes smaller. Reduced stroke volumes and increased resistance in…

…embolism (PE). Hemodynamic effects Pulmonary embolism leads to increased resistance in the main pulmonary artery, and thereby increased afterload on the right ventricle. This increases…
