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). WebbEven the relatively small increase in Pa O2 in the control group was associated with a decrease in hematocrit from 33% to 28%. However, despite rather large increases in Pa O2 with hemodilution (mean increases of 50, 98, and 72 mmHg in the three groups), the authors suggest that the changes were not statistically significant. chr pain syndromeWebbQuestion: Which of the following would decrease the partial pressure of oxygen (PO2) in arterial blood?
