Rapid shallow breathing evoked by selective stimulation of airway C fibres in dogs

AUTOR(ES)
RESUMO

1. We have examined the reflex changes in breathing evoked in anaesthetized dogs by stimulation of the afferent vagal C fibres that supply the intrapulmonary and lower extrapulmonary airways. We stimulated bronchial (intrapulmonary) C fibres selectively by injecting bradykinin into the right bronchial artery (the chest had been opened briefly for insertion of a bronchial arterial catheter).
