Neurophysiology of the cough reflex.
Cough is due to activation of sensory receptors in the larynx and lower respiratory tract, sending impulses to the brainstem. The central organization of cough is poorly understood. The afferent pathways for cough are from receptors in and under the epithelium of the airways. These receptors are rapidly adapting, with thin myelinated fibres in the vagus nerves, which can be directly stimulated ...
متن کاملVolitional control of reflex cough.
Multiple studies suggest a role for the cerebral cortex in the generation of reflex cough in awake humans. Reflex cough is preceded by detection of an urge to cough; strokes specifically within the cerebral cortex can affect parameters of reflex cough, and reflex cough can be voluntarily suppressed. However, it is not known to what extent healthy, awake humans can volitionally modulate the coug...

متن کاملSensitivity of the cough reflex in patients with chronic cough.
Cough may occur in association with excess bronchial secretions and may, therefore, be productive. However, in a proportion of patients the cough is non-productive and a possible association with an enhanced response of the cough reflex has been postulated. Using the irritant capsaicin, the sensitivity of the cough reflex was measured in 363 individuals. A questionnaire was used to divide subje...
متن کاملA novel reflex cough testing device
BACKGROUND The reflex cough test is useful for detecting silent aspiration, a risk factor for aspiration pneumonia. However, assessing the risk of aspiration pneumonia requires measuring not only the cough reflex but also cough strength. Currently, no reflex cough testing device is available that can directly measure reflex cough strength. We therefore developed a new testing device that can ea...
