Calculate cardiac output if the heart rate is 85 beats/minute,end-diastolic volume (EDV)is 130 ml,and end-systolic volume (ESV)is 60 ml.
A)16,140 ml/min
B)7800 ml/min
C)5100 ml/min
D)5950 ml/min

Quizplus · Accepted Answer

Cardiac output (CO) can be calculated using the formula:
CO = heart rate (HR) x stroke volume (SV)
SV = EDV - ESV
Substituting the given values:
SV = 130 ml - 60 ml = 70 ml
CO = 85 beats/min x 70 ml/beat = 5950 ml/min 
Therefore, the correct answer is D.
