The EMGdi response to both isocapnic hypoxia and hyperoxic hypercapnia was studied in the same sitting in six normal subjects. Rebreathing methods achieving "open loop" conditions were used. EMGdi was quantified as a moving time average. In almost all subjects, during hypoxia changes in EMGdi were inversely and hyperbolically related to changes in PAO2.(More)
W e have evaluated the relationship between respiratory nerve and muscle electrical activity and airway occlusion pressure in both anesthetized animals and conscious humans. This relationship which reflects the coupling of the neuromuscular components of the respiratory control system was studied under conditions of unloaded and loaded breathing. In(More)
