Ventricular Volumes 

Check your answers below. 

With Venticlar volumes, if you have two volumes you can always solve for one unknown volume. This is basic algebra: SV = EDV  ESV
Stroke volume: Blood ejected from heart (left ventricle) per beat (the average is 6080 ml/beat)
EDV: Enddiastolic volume (ventricle is filled)
ESV: Endsystolic volume (blood left in ventricle after ejection


Now, see if you can solve a few word questions with ventricular volumes. 

Now, check your answers below. 


Ejection Fraction Calculations 

Ejection fraction is solved by dividing Stroke Volume (SV) by End Diastolic Volume (EDV). Then, you multiply your calculation by 100 to get the percent. Ejection faction is presented in a percent.
An average ejection fraction classification is 60%
If the ejection fraction is higher than 60% then the classification is Above average
If the ejection fraction is less than 60% then the classification is Below average.

Now, try working a word problem with ejection fraction.
