Study Notes
Dalton's Law of Ideal Gas Mixtures
- The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture.
- The partial pressure of a gas measures its thermodynamic activity.
Partial Pressure and Gas Behavior
- Gases dissolve, diffuse, and react according to their partial pressures.
- The behavior of gases is not determined by their concentrations in gas mixtures or liquids.
Arterial Blood Gas Tests
- Important parameters in tests of arterial blood gases include the partial pressure of oxygen (pO2) and other relevant gas concentrations.
Gas Mixtures and Ratios
- Mixture ratios, such as 20% oxygen and 80% nitrogen, are determined by the partial pressures of each gas in the mixture.
- The symbol for pressure is usually P or p, which may use a subscript to identify the specific gas.
