The response of laryngeal airway resistance to pulmonary receptor stimulation was studied in 20 mongrel dogs anesthetized with alpha-chloralose (80 mg/kg). Stimulation of pulmonary stretch receptors by lung inflation inhibited the phasic variation of laryngeal resistance during respiration and produced a sustained reduction of laryngeal resistance, which was related to lung inflation pressure. Stimulation of pulmonary J-receptors with capsaicin produced apnea and a large increase in laryngea resistance. Capsaicin produced this reflex when injected into the pulmonary circulation but not when injected into the systemic circulation...
