Cardiac Cycle/ Output Flashcards
Indicates total blood flow throughout the body which in turn is indicative of ventricular efficiency
Cardiac output
Amount of blood pumped out by each ventricle in 1 min
Cardiac output
How do you determine cardiac output
Multiply heart rate in beats/min by the stroke volume
Volume of pumped blood by one ventricle with each beat
Stroke volume
Difference between resting and maximal CO
Cardiac reserve
EDV-ESV
Stroke volume
Maximum amount of blood that ventricles will hold during cardiac cycle
EDV
End of ventricular (diastole)
Do ventricles completely empty after systole
No
Amount of blood left in the ventricles at the end of contraction
End systolic volume
Minimum amount of blood that ventricle will contain during one cardiac cycle
ESV
Exercise will ___ stroke volume
Increase
Slow heart beat ___ stroke volume
Increases
Low venous returns __ SV
Decreases
Extremely rapid heart rate __ EDV
Decreases
Epinephrine norepinephrine glucagon thyroxine causes great blood ejection causing __ SV and __ ESV
Greater SV
Lower ESV
