Equations for Test 2 Flashcards
1
Q
Pulse pressure=
A
SBP-DBP
2
Q
MAP=
A
(SBP+ 2 DBP)/3
OR
MAP= CO X SVR <— only use in SYSTEMIC circulation. negates CVP which is
“small” value per garman
3
Q
CO=
A
HR x SV
4
Q
CI=
A
CO/m2 (m2= Body surface area)
5
Q
Q=
A
Q= (P1-P2)/R
or
Q= π(P1-P2)r4/ 8nL
6
Q
What is poiseuille’s law
A
R= n x L x 8/ πr4
7
Q
EF=
A
SV/EDV
OR
EF=(EDV- ESV)/EDV
8
Q
SV=
A
LVEDV-LVESV
9
Q
Resistors in series?
A
R= R1+R2+R3
10
Q
Resistors in parallel?
A
1/Rtotal= 1/R1+ 1/R2+ 1/R3
11
Q
Reynold’s number?
A
Re= pDv/n
p= densirty
D= diameter
v= velocity
n= viscosity
12
Q
Wall tension?
A
T= Pr
13
Q
Q= (think r/t speed)
A
V x A
14
Q
Fick’s?
A
CO= O2 consumption/ (a-v)o2
15
Q
