WebbThe partial pressure of a gas can be calculated using the ideal gas law, which we will cover in the next section, as well as using Dalton's law of partial pressures. Example 1: Calculating the partial pressure of a gas Let's say we have a mixture of hydrogen gas, \text H_2 (g) H2(g), and oxygen gas, \text O_2 (g) O2(g). Webb8 dec. 2024 · The partial pressure of carbon dioxide in the alveolus will obviously be quite variable, but under normal conditions the partial pressure of the alveolar oxygen will drop by about 50mmHg, down to 99. The precise extent of the drop can be established from the alveolar gas equation ( Fehn, Rahn, and Otis, 1946 ).
