As pressure increases underwater, the increased pressure of each of the gases in the air we breathe has physiological effects. Henry’s Law
Henry’s Law (Solubility of gases) Henry’s Law: The amount of gas that will dissolve in a liquid is directly proportional to the pressure of the gas.
Gases go into and come out of solution in our body as the pressure of the gas changes. When we dive, we “ingas”; then when we surface, we “offgas.” Dalton’s Law
Dalton’s Law (Partial pressures) Dalton’s Law: The total pressure exerted by a mixture of gases is equal to the sum of the pressures of each gas.
