Cardiac output, heart rate and stroke volume Flashcards
1
Q
What is cardiac output a combination of?
A
Heart rate and stroke volume
2
Q
What is the equation which equals to cardiac output?
A
cardiac output = stroke volume × heart rate
3
Q
What is cardiac output?
A
The amount of blood which is pumped out of the left ventricle of the heart per minute
4
Q
What is stroke volume?
A
The amount of blood that is pumped of of the left ventricle per beat
5
Q
What is heart rate?
A
The number of beats per minute
6
Q
How do you work out your beats per minute?
A
Find your pulse in your neck (carotid pulse) or on your wrist (radial pulse).
Count for 15 seconds x 4 = ____ Beats per minute
