Cardiac Output Flashcards
Ejection fraction
Stroke volume/max volume of blood in left ventricle
Cardiac output units
Ml/min
Stroke volume units
L/min
Heart rate units
Beats per min
Stroke volume
Diastolic-systolic
Cardiac output
Stroke volume x heart rate
What causes the aortic valve to open?
When the pressure in the ventricles is greater then the pressure in the aorta
What causes the aortic valve to close?
When the pressure in the ventricles is less than the pressure in the aorta
What causes the AV valves to close?
When there’s sure in the atria is less than the pressure in the ventricles
What causes the AV valves to open?
When the pressure in the atria is greater than the pressure in the ventricles
Cardiac output:
The total quantity of blood pumped by the left ventricle in one minute
Stroke volume:
The quantity of blood pumped by the left ventricle during each contraction of each cardiac cycle
Heart rate:
The number of cardiac cycles in one minute
