Abstract:

The biofeedback was used in the training of rats to decrease their spontaneous tidal volume in conditions of normoxia, hypoxia and hypercapnia. All rats decreased tidal volume in the ranges equal to 1.0 VT and 0.8 VT in the air and hypoxic conditions. It was difficult for them to decrease tidal volume in hypercapnia. The role of hypoxic and hypercapnic drives in respiratory responses to a breathing regimen and its abolition, is discussed.
