Behaviour of canine pulmonary vagal afferent receptors during sustained acute pulmonary venous pressure elevation.

1. The effects of an acute sustained increase in pulmonary venous pressure induced by partial obstruction of the mitral valve on the activity of the four types of pulmonary receptors, namely, slowly adapting, rapidly adapting, pulmonary C-fibre and bronchial C-fibre receptors, were studied in the dog. 2. Fifteen slowly adapting receptors, eleven rapidly adapting receptors and nine bronchial C-fibre receptors showed significant sustained …
