CORRECT Answers
what is stroke volume (SV) volume of blood ejected during one contraction of left ventricle
when is end of diastole right before ejection
what volume of blood does lv (left ventricle) have 120 ml
volume of blood of 120 ml of lv at end of diastole is end diastolic volume (edv)
known as
how many ml of blood does contraction eject 60-80
stroke is equal to one heart beat
when is there 120 cc's when blood is filling ventricle
what is cc cubic cm (same as ml)
when there's 120 ml of blood in ventricle how many ml 60-80 ml
does lv eject
lvesv left ventricular end systolic volume
lv esv is sv (stroke volume) of blood known as esv (end systolic volume)
esv is how many ml 40
what is esv left over blood in ventricle saved for extra pumping if needed (getting chased
by bear)
how do you evaluate heart performance ejection fraction (ef)
what does EF reflect percentage of edv that's pumped with each heart beat
EF= sv/edv
normal ef 55-70%
below ef= weak= heart has little pumping= slower times (possible disease in limbs from
not getting enough blood flow- may have purple toes)
above ef= heart is working too hard
ef is the overall strength of patients heart
what are 2 things that affect EF systemic and cardiac factors
cardiac output= sv times patients heart rate
