Question

What are the normal values for EF, FS, SV, and CO?

Answer 1

The normal values for EF, FS, SV, and CO are between 55-70% for EF, 25-45% for FS, 55-100mL for SV, and 4.0-8.0L/min for CO.

Step-by-step explanation:

The normal values for EF, FS, SV, and CO are:

• EF (ejection fraction) ranges from approximately 55-70 percent, with a mean of 58 percent.
• FS (fractional shortening) is calculated by subtracting the end-systolic dimension from the end-diastolic dimension, dividing the result by the end-diastolic dimension, and multiplying by 100. The normal range for FS is typically between 25-45 percent.
• SV (stroke volume) is the difference between the end-diastolic volume (EDV) and end-systolic volume (ESV). A mean SV for a resting individual is approximately 70 mL, but the normal range is 55-100 mL.
• CO (cardiac output) represents the volume of blood pumped by the heart in one minute. The mean CO is 5.25 L/min, with a range of 4.0-8.0 L/min.
