Review Neurophysiology of the motor output pattern generator for breathing. The Hering–Breuer inflation reflex, named for Josef Breuer and Ewald Hering, is a reflex triggered to prevent the over-inflation of the lung. Pulmonary stretch receptors present on the wall of bronchi and bronchioles of the airways respond to excessive stretching of the lung during large inspirations. Once activated, … See more Josef Breuer and Ewald Hering reported in 1868 that a maintained distention of the lungs of anesthetized animals decreased the frequency of the inspiratory effort or caused a transient apnea.

WebBreuer, working under Ewald Hering at the military medical school in Vienna, was the first to demonstrate the role of the vagus nerve in the reflex nature of respiration. This was a departure from previous physiological understanding, and changed the way scientists viewed the relationship of the lungs to the nervous system.

WebIn- fants have an active Hering–Breuer reflex that decreases with age but is still present during early childhood (26). Clinically, this can be a problem for children receiving continuous posi- tive airway pressure (CPAP), who sometimes develop central apnea during positive pressure application (27). WebThere are pulmonary stretch receptors in the lungs. Once these stretch receptors are activated, action potentials travel through the Vagus nerve to the inspiratory VRG area of the medulla and turn off or inhibit the signal of the inspiratory VRG to inhibit inspiration and begin expiration. This is known as the Hering-Breuer Inspiratory Reflex.

WebPulmonary stretch receptors are mechanoreceptors found in the lungs . When the lung expands, the receptors initiate the Hering-Breuer reflex, which reduces the respiratory rate. This signal is transmitted by vagus nerve. Increased firing from the stretch receptors also increases production of pulmonary surfactant .
