Ventilatory and Upper Airway Muscle Responses to Upper Airway CO2 in Anaesthetized Neonatal Guinea-Pigs
In adult animals, CO2 confined to the isolated upper airway (UA) lumen reflexly inhibits breathing and excites genioglossus muscle activity (Nolan et al, 1990) by affecting the activity of CO2-sensitive receptors...

The Effect of Sympathetic Nerve Stimulation on Ventilation and Upper Airway Resistance in the Anaesthetized Rat
We have previously demonstrated that moderate cooling of the isolated upper airway (UA) causes a substantial fall in UA resistance in anaesthetized rats (O’Halloran et al, 1994). This effect is partly of refle...
