Question: what is the relationship between alveolar ventilation and paco2?
Answer: 1 The relationship of alveolar ventilation ( ˙VA) to the resulting PaCO2 for constant ˙VCO2 is a non-linear one. It is a rectangular hyperbola. Fig. 2 The alveolar gas equation predicts a relationship of inspired oxygen partial pressure (PIO2) to the resulting alveolar partial pressure (PAO2) that is linear.
