This study was performed to evaluate the characteristics of esophageal receptors in anesthetized and artificially ventilated dogs. The electrical activity of the esophageal afferents was recorded from the peripheral cut end of the cervical vagus nerv

Bronchoconstriction in asthmatic patients is frequently associated with gastroesophageal reflux. However, it is still unclear whether bronchoconstriction originates from the esophagus or from aspiration of the refluxate into the larynx and larger air

Pressure changes in the cuff of an endotracheal tube (Pcuff) were measured as an index of the tracheal smooth muscle activity and compared with total lung resistance (RL) in anesthetized, paralyzed and artificially ventilated dogs. After obtaining pa

The superior laryngeal nerve (SLN) is the main source of laryngeal afferent activity. A clear respiratory modulation can be noted when recording from the peripheral cut end of this nerve in several mammalian species. This modulation is due to three t

It has been previously found that volatile anesthetics significantly affect the activity of laryngeal receptors. In this study we have investigated the respiratory effects of these volatile anesthetics delivered into the upper airway of newborn and a

The aim of this study was to establish the cranio-caudal distribution of slowly (SAR) and rapidly (RAR) adapting receptors of the extrathoracic trachea (ETT) as well as their innervation and response to water solutions of different compositions. Expe

Although constant airflow through the upper airway has been shown to induce ventilatory depression in anesthetized newborn animals, the role of laryngeal temperature in this response has not been studied. Experiments were performed in fourteen 1-5 da

The purpose of this study was to relate the carbon dioxide (CO2) response of laryngeal receptors to their behavior during the breathing cycle (i.e, their response to transmural pressure changes, laryngeal movement or decreases in temperature)_or duri

Numerous protective and defensive reflexes are elicited from the upper airway, but the extent to which receptors with myelinated and nonmyelinated fibers contribute to these reflex responses is not known. In this study we compared the effects of caps

Gastroesophageal reflux has been indicated as an etiopathological factor in disorders of the upper airway. Upper airway collapsing pressure stimulates pressure-responsive laryngeal receptors that reflexly increase the activity of upper airway abducto
