Cardiac output is the product of stroke volume and heart rate.
Cardiac output (CO) = Stroke volume (SV) X heart rate (HR)
James stroke volume = 70 milliliters/beat and heart rate = 75 beats/minute
CO= 70 x 75 = 5250
James cardiac output CO = 5250 mL/minute
Step-by-step explanation:
The cardiac function can be assessed by measuring the cardiac output. Cardiac output denotes the “total amount of blood pumped by the heart in one minute”. It is the amount of blood flowing through the circulatory system in one minute and depends on the two variables – stroke volume and heart rate and is the product of both the variables.
Stroke volume is the “total amount of blood pumped out by the left ventricle during one contraction”.
Heart rate refers to the “number of times the heart beats in a minute” or the “number of contractions of the ventricles in a minute".
