... sensation seen with hypercapnia. 2. To investigate this we measured hypercapnic re-breathing responses in seven normal subjects (six males, age range 21–38 years) with and without an inspiratory resistive load of 10 cm H 2 O. Pleural and transdiaphragmatic pressures, mouth occlusion pressure and breathing...

Six normal naive subjects scaled breathlessness using a visual analogue scale, during steady-state exercise. Further changes in this sensation were induced by either sustained hypercapnia or acute hypoxia; these...

...J. M. Low; T. Gin; T. W. Lee; K. Fung 1. Plasma concentrations of noradrenaline and adrenaline were measured in 11 anaesthetized patients during normocapnia, hypocapnia and hypercapnia. Hypocapnia was produced by deliberate hyperventilation and hypercapnia by adding carbon dioxide to the inspired...
