Question

Due to a congenital defect in his pulmonary circuit, Alphonse experiences increasing right ventricular failure as a result of obstructed pulmonary circulation. What would be the impact on her stroke volume, heart rate and mean arterial pressure?

Paco mixes up his anti-inflammatories and his heart meds, and accidentally takes a triple dose of beta blockers.

• How do beta blockers work?
• What would be the impact on his stroke volume, heart rate and mean arterial pressure?

Answer 1

Alphose stroke volume will decrease dramatically as when the pulmonary circulation is obstructed the ability of blood to reach the left side of heart is reduced . When the pulmonary circulation is obstructed it will lead to reduction in the blood movement from the right ventricle ti the left atrium of our heart .so stroke volumes will decrease

Heart rate will increase tremendously as a result of this obstruction to overcome the need for blood supply

Also the mean arterial pressure will also increase to maintain the blood supply
