Physio Law, Equations and Numbers

Question 1

Capacitance

Answer 1

C = V/P

Question 2

Cardiac Output

Answer 2

CO = [MAP-RAP]/TPR

Question 3

Ejection Fraction

Answer 3

EF = SV/EDV (N=0.55)

Question 4

Fick principle

Answer 4

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

Question 5

Goldman

Answer 5

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

Question 6

Laplace

Answer 6

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

Question 7

Nernst

Answer 7

Equilibrium potential

Question 8

Poiseuille

Answer 8

Resistance (viscosity x length / r4

Question 9

Reynolds number

Answer 9

Predicts turbulent (�)/laminar (�) flow

Question 10

Van�t Hoff�s

Answer 10

Osmotic pressure (_ = g x C x RT)

Question 11

Winter�s Formula (metabolic acidosis)

Answer 11

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