Question

A patient has blood pressure of 120/80 a stroke volume of 70 ml and an EDV of 140 ml. what is the ESV ?
please show your work.

Answer 1

End systolic volume (ESV) = amount of blood left in the ventricle after ventricular systole

End diastolic volume = amount of blood in the ventricle after vetricular diastole.
Stroke volume = amount of blood ejected from ventricle after ventricular diastole.

stroke volume = 70 ml ; EDV = 140 ml
Stroke volume = end diastolic volume – end systolic volume

Or

end systolic volume = end diastolic volume - stroke volume

end systolic volume = 140-70 = 70ml

ESV = 70ml
