Abstract
The injection of an aerosol containing a chemostimulant into a patient's throat to stimulate nociceptor (irritant) and c-fibre receptors is augmented by the inclusion of a medically safe and accepted contrast substance, such as barium. The addition of a contrast substance to the aerosol allows fluoroscopic observation of the patient's (larynx) response, to facilitate a medical practitioner's identification of whether the patient is at risk to one or more abnormal physiological conditions, such as oral or pharyngeal dysphagia, and pneumonia.
