Interrelation of respiratory variability and ventilatory sensitivity to a hypercapnic stimulus

: Breathing variability and ventilatory response to carbon dioxide (SCO2) were studied after premedication with moradol, in healthy subjects and those with acute pain syndrome. Inverse relationship between SCO2 and breathing variability was established. SCO2 was the highest in the group of patients with acute pain syndrome and the lowest in patients after premedication with moradol.
