Web1 Jan 2009 · Background: Changes in body temperature have important impact on measurements of blood gases. In blood gas analyzers the samples are always kept constant at a temperature of exactly 37°C during the measurements, and therefore results are not correct if body temperature differs from 37°C. Web3 Nov 2024 · Temperature affects the equilibrium constant for the solvation process (k): the solubility of O2 and CO2 is increased at low temperatures. Thus at low temperatures, there will be a lower partial pressure for a higher dissolved concentration of gas. Oxygen and …
