After being shot multiple times while robbing the
Circle K, Thelma is losing a lot of blood. What would be the impact
on her stroke volume, heart rate and mean arterial
pressure?
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?
question 2
Answer: Alphonse experiences increasing right ventricle failure.
The deoxygenated blood from the Superior and inferior vena cava, goes to the right atrium and goes to right ventricle and then it goes to lungs for purification of the blood. Capillary bed will helps the make the deoxygenated blood to oxygenated blood and then it travels to the left atrium and left ventricle and finally goes to the aorta and supplies all over the body.
when right ventricle get failure there will be only decreased blood travels from right ventricle to lungs via pulmonary artery. After that only less amount of the blood get oxygenated and goes to left ventricle.
Stroke volume: Amount of the blood comes from the left ventricle and goes to the aorta via aortic valve in one minute.
Heart rate : When the right ventricle is failure, so the heart will works to much to Pump the blood from right ventricle to lungs. It leads to Increased heart rate.
Mean atrial pressure: while the cardiac cycle occurs in the heart, There will be some pressure in the arteries. It is considered as the mean atrial pressure. Normal person have 70-100 mmHg.
In right ventricle failure, There will be 30-40 mmHg pressure in the arteries. It shows that the mean atrial pressure get decreased in this condition.
