Am u bag being squeezed
Charles law
Volume is directly related to temp under constant pressure

Pressure is related to temp at a constant volume
O2 tank on a hot loading dock
Dalton’s law
Total pressure is equal to sum of all partial pressures.
Allows us to calculate partial pressure as with pediatric induction
- 3o2x 760= 228mmhg
- 7n2ox760= 532 mmhg
Henry’s law
Gas that dissolves in liquid such as O2,0.003xpa02
Avagadros number
6.023x10-23
Number of molecules in a mole
A mole occupies 22.4 liters
Vapor pressure math
Second added to container
(760-170)/760= x100= % O2 in the air
170/760= x100= to the pct added
Flicks law
Every time a gas is diffusing. (Explains second gas effect)
Diffusion is proportional to membrane area, partial pressure, solubility and inverse to molecular weight.
Explains diffusion hypoxia, and why co2 diffuses faster than O2
Graham’s law
Plays off of flicks law, saying that heavier molecules diffuse slower.
Heat loss
Greatest to least
Radiation
Convection
Evaporation
Conduction
Law of Laplace
Tension= pressure x radius
In blood vessels increase blood pressure= increase tension
In lungs if surfactant is normal then pressure remains constant and will tension increases with radius.
Lungs absent of surfactant the WALL TENSION is constant smaller alveoli empty into larger.
Laminar flow
Reynolds number below 1500
