“…In humans, it is not known how much mucus is required and where it has to be located for the human ear to detect presence of a moist cough. It is likely that mucus in the large airways is required for detectable difference in cough quality as the sound of cough is generated from vibration of larger airways and laryngeal structures during turbulent flow in expiration [16,17]. Laminar airflow, which occurs in smaller airways, is inaudible [31].…”

“…Our study findings support this and it is not surprising that when the cough is dry, BS grades were less. The rheological properties of airway mucus also influence cough sound [17]. It is not known how airway secretions in the more peripheral airways influences the sound of cough.…”

“…The sound of a cough is due to vibration of larger airways and laryngeal structures during turbulent flow in expiration [16,17]. It is not known which generation of the airways is involved when the human ear identifies a wet cough and currently there are no validated human models that allow measurement of increased airway mucus.…”

“…However, it is not known as to how differences in vocal fold configuration influence the acoustics of cough in both sexes. Hashimoto et al (2003) demonstrated the effect of the rheological properties of airway mucus to cough sound production. Their study was based on examination of voluntary cough and sputum from patients with chronic productive cough.…”

Cough is the most common presenting symptom to medical practitioners to the USA and Australia. Worldwide, the desire to reduce the impact of the symptom of cough is reflected in the billions of dollars spent on over the counter cough medications. Easy to apply and clinically relevant definitions of cough are necessary for effective communication and to progress clinical research. Based on current data, pediatric cough definitions have been formulated on timeframe (acute and chronic), clinical cough characteristics (dry vs wet/productive and classical recognizable cough sounds) and suggestive broad underlying etiology categories (expected cough, specific cough, non-specific cough and protracted bronchitis). These definitions are distinct from adult definitions, as many of adult-type aspects of cough cannot be applied to young children. With the lack of pediatric data, adult data is often inappropriately extrapolated to children.In the second part of this paper, the evidence for and against the use of the various pharmaceuticals (such as OTC medications, antimicrobials, treatment for gastroesophageal reflux and asthma) for cough in children are reviewed. The utility of 'time to response' is important in the management of cough in children to minimize possible associated morbidity of the therapies for non-specific cough.
