The ability to cough to remove lung secretions is often impaired when the patient is unconscious or when neurological pathology presents. Removal of lung secretions requires frequent invasive bronchial suction in these circumstances. This article reports on trials of a novel ultrasonic cough stimulator (CoughStimTM) that consistently and comfortably stimulated a moderate to strong cough when applied to the side of the neck of nondisabled subjects and those unable to cough on demand. Results suggest the new ultrasound cough stimulator might be a viable alternative to invasive bronchial suction for removal of secretions in vulnerable elderly adults.
