In lung disease, when too much H+ diffuses into CSF, HCO3- is retained by kidneys and actively/passively diffuses into CSF to buffer excess H+, usually with a corresponding drop in PaO2 < 60 mmHg.
Based on the fact that the SO2, O2 Content and HCO3- do not change with changes in temperature, it is argued that acid-base status does not change when temperature changes under the alpha-stat regulation mechanism.
