Q

Boyle’s Law

A
  • The Volume of a gas is inversely proportional to its pressure, assuming temperature is constant
  • (P1)(V1)=(P2)(V2)

Q

Stagnant Hypoxia

A

a. You are able to get oxygen into your lungs and you are able to load oxygen onto hemoglobin. But for some reason the blood is not able to move due to one of below reasons.
b. Occurs when cardiac output fails to meet the metabolic demand of the tissues
c. Test Tip: You are a train station. You have a lot of people in the station (O2 molecules) and plenty of train cars (Hgb) but the train cars are broke and can’t go anywhere.

25
Q

Hypemic Hypoxia

A

Q

Dalton’s Law

A
  • The total pressure in a container is the sum of the partial pressure (“the gang”) of all the gases in the container.
  • Pt=P1+P2+P3+P4 .

“Dalton’s Gang”

41
Q

Charles’ Law

A
  • Which states that changes in temperature will cause a change in volume assuming pressure is constant
  • P1/T1=P2/T2

“Charles Centigrade”
“Charles is a hot head”

42
Q

Gay-Lussac’s Law

A

• The pressure of a fixed amount of gas at a fixed volume, proportional to the temperature
• Similar to Charle’s Law
o “Gay-Lussac is Charles’s gay brother.”
o Sames as Charles’s Law only in a vessel with a fixed size
o Gay-Lussac is about pressure

43
Q

Henry’s Law

A

• At a constant temperature the amount of gas dissolved in a given volume of liquid is directly proportional to the partial pressure of that gas in the gas phase

“Henry’s Heineken”

44
Q

Graham’s Law

A
  • The rate of diffusion through a liquid medium is directly related to the solubility of the gas and inversely proportional to the square root of its density
  • Translation: At equal pressure and temperature, gases with a smaller mass will diffuse faster than gases with a larger mass.

“Graham’s Grape Jelly”
