From a bedside capnograph (CO₂ measuring device), you obtain a "dry" gas reading of 5.3% CO₂ in a patient's exhaled gas. Given a barometric pressure of 765 mm Hg, what is the partial pressure of CO₂ in this patient's exhaled gas?

Question

Quizplus · Accepted Answer

Dalton's law describes the relationship among the partial pressure and the total pressure in a gas mixture. According to this law, the total pressure of a mixture of gases must equal the sum of the partial pressures of all component gases. Moreover, the principle states that the partial pressure of a component gas must be proportional to its percentage in the mixture.
