What is the mean stroke volume for a resting 70 kg individual?
AAbout 30 mL
BAbout 130 mL
CAbout 200 mL
DAbout 70 mL
Answer & Solution
Correct answer: D. About 70 mL
1. Stroke volume varies with heart size, condition, sex and contractility.
2. A mean value for a resting 70 kg individual is approximately 70 mL.
3. That sits at the low end of the usual 70 to 80 mL range.
