Laryngeal Contribution to Respiratory Pattern in Anesthetized Rabbits

There have been a number of animal and human studies regarding the larynx as an effector organ of ventilatory control (Brancatisano et al., 1983; England et al. 1982; Gautier et al., 1973; Remmers and Bartlett, 1977). These experiments were based on the normal route of airflow through the upper airways. The purpose of the present study was to delineate the role of the larynx as the flow limiting segment and presumable respiratory timing controler. We have compared the effect of breathing via tracheostomy or via larynx (supralaryngeal airway being removed from the airflow path) on respiratory airflows and timing in spontaneously breathing rabbits. The measurements were made in control conditions and after section of the laryngeal nerves and cervical vagi.
