CO2 homeostasis is maintained in conscious humans by regulation of tidal volume, but not of respiratory rhythm
Graphical abstract Highlights ► We measured end-tidal CO2 fraction during two types of volitional breathing. ► Either (1) respiratory frequency or (2) tidal volume was volitionally constrained. ► CO2 level was maintained when respiratory frequency was volitionally constrained. ► CO2 level was decrea...
