CARDIO General Formulas Flashcards
1
Q
BP =
A
CO X SVR
2
Q
CO =
A
HR X SV
3
Q
SV =
A
EDV - ESV
4
Q
MAP =
A
SBP + (2X DBP )
________________

5
Q
normal MAP is
A
> 60 mmHg which can sustain organ pefusion
6
Q
Pulse pressure -
A
SBP - DBP
7
Q
EF =
A
SV x 100
___
EDV
8
Q
BSA =
A
____________________________
/WT (kg ) x Ht (cm) / 3600

9
Q
CI
A
CO/BSA
10
Q
marker of cardiac function in relation to BSA, thus relating heaty performance to the size of the individual
A
Cardiac index (CI)
11
Q
better indicator of metabolic mass than body weight
A
body surface area
12
Q
most useful index of LV function
A
Ejection fraction (EF)
13
Q
Fraction of blood ejected by LV during systole
A
EF
14
Q
represents the force that the heart generates everytime it contracs
A
pulse pressure
15
Q
normal pulse pressure
A
usually 30-40 mmHg
