Carbon Dioxide Absorption Is Not Linearly Related to Intraperitoneal Carbon Dioxide Insufflation Pressure in Pigs

Abstract

By considering Fick's law of diffusion, the initial increase in VCO2 is likely accounted for by increasing peritoneal surface area exposed during insufflation. The continued increase in PaCO2 without a corresponding increase in VCO2 is accounted for by increasing respiratory dead space.
