Reflex prolongation of stage I of expiration

Abstract

Experiments were performed on anesthetized cats to test the theory that the interval between phrenic bursts is comprised of two phases, stage I and stage II of expiration. Evidence that these represent two separate neural phases of the central respiratory rhythm was provided by the extent to which stage duration is controlled individually when tested by superior laryngeal, vagus and carotid sinus nerve stimulation. Membrane potential trajectories of bulbar postinspiratory neurons were used to identify the timing of respiratory phases. Stimulation of the superior laryngeal, vagus and carotid sinus nerves during stage I of expiration prolonged the period of depolarization in postinspiratory neurons without significantly changing the durations of either stage II expiratory or inspiratory inhibition, indicating a fairly selective prolongation of the first stage of expiration. Changes in subglottic pressure, insufflation of smoke into the upper airway, application of water to the larynx or rapid inflation of the lungs produced similar effects. Sustained tetanic stimulation of superior laryngeal and vagus nerves arrested the respiratory rhythm in stage I of expiration. Membrane potentials in postinspiratory, inspiratory and expirator...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
