Pulmonary denervation
WebWe have studied two aspects of this classic Breuer-Hering reflex in humans: the effect of pulmonary denervation from bilateral lung transplantation, and the effect of alveolar hypocapnia. Lung inflations were performed in six normal subjects and four lung transplant patients during triazolam-induced sleep using a negative pressure body box.
