Flashcards in Physio Law, Equations and Numbers Deck (11):
1

Capacitance

C = V/P

2

Cardiac Output

CO = [MAP-RAP]/TPR

3

Ejection Fraction

EF = SV/EDV (N=0.55)

4

Fick principle

Cardiac output = O2 consumption / [O2(PV) _ O2 (PA)]; PV = peripheral arterial blood, PA=systemic venous

5

Goldman

Resting membrane potential (also called transference or chord conductance equation)

6

Laplace

P = 2T/r (surface tension vs radius)

7

Nernst

Equilibrium potential

8

Poiseuille

Resistance (viscosity x length / r4

9

Reynolds number

Predicts turbulent (�)/laminar (�) flow

10

Van�t Hoff�s

Osmotic pressure (_ = g x C x RT)

11

Winter�s Formula (metabolic acidosis)

PCO2=1.5(HCO3) + 8 +/- 2
