Question

Calculate the cardiac output of a patient with a heart rate of 100 beats/minute and a stroke volume of 75 ml.

Answer 1

ANSWER:

Cardiac output(CO) in L/min = stroke volume(SV) X Heart rate(HR)

Therefore,

CO= 100 x 75= 7500 ml/min

CO= 7.5 L/min

EXPLANATION:

CARDIAC OUTPUT is the volume of blood, pumped by the heart, that goes through the systemic circulation every minute. It is determined by the stroke volume and heart rate.

STROKE VOLUME is the volume of blood ejected from the ventricles of the heart in each contraction.

HEART RATE is the number of times the heart beats in a minute.
