Does anyone know about interpreting cardiac output and ejection fraction?

In brief: I hope so!

It's part of what cardiologists do for a living.
Ejection fraction is the percentage change in ventricular volume in one beat. 55% or better is normal but >75% suggests a hyperdynamic state which may be physiologic or pathologic. Cardiac output is the volume of blood (in liters per minute) that the heart pumps. Co is the product of stroke volume (blood in ccs per beat) x the heart rate (bpm).
