Pressure of the blood coming out of the heart?
This pressure is termed the aortic pressure.
What event results in the pressure deflection called the dicrotic notch?
When the aortic semilunar valve snaps shut, a momentary increase in the aortic pressure results from the elastic recoil of the aorta after valve closure.
How can severe aortic insufficiency be treated?
Severe aortic insufficiency can be treated with medical therapy. Pharmaceuticals to decrease blood pressure, with diuretics and vasodilators, are helpful in patients with aortic insufficiency.
What are the conditions where you get 0 diastolic blood pressure?
aortic regurgitation
What is the major determinant of the left ventricular preload?
aortic diastolic pressure
When pressure in the aorta rises due to atherosclerosis does more ventricular pressure open the aortic valve?
yes
What in the carotid sinuses and aortic arch detect increases in blood pressure?
baroreceptors
What are baroreceptors in the carotid sinus and aortic arch sensitive to?
changes in arterial pressure
Chemoreceptors in the aortic and carotid bodies?
it helps in regulation the blood pressure .
What causes the aortic semilunar valve to close?
Higher pressure on the convex side (from the heart contracting) than the concave side causes them to open. When the pressure reverses (the heart relaxes) they close.
If the aortic valve could not close completely would the diastolic or systolic pressure be affected?
Diastolic, because it would lower the pressure.
Would the blood pressure rise or fall if a patient suffers an aortic aneurism?
It would rise
