Airflow Features Obtained From Voluntary Throat Clearing Compared to Voluntary Cough and Induced Reflexive Cough in a Healthy Population.

ABSTRACT:

Background

Coughing and throat clearing are different airway protective manoeuvres elicited in the framework of dysphagia. However, coughing and throat clearing may be auditorily confused during a clinical swallowing evaluation. In addition, literature reporting comparisons between coughing and throat clearing via gold standard airflow metrics is lacking.

Aims

To report quantitative airflow data for voluntary throat clearing, and to examine in a healthy population the aerodynamical differences between voluntary throat clearing, voluntary cough and induced reflexive cough.

Methods and procedures

Forty healthy participants were included in the study. Airflow measurements were obtained from single voluntary throat clearings, single voluntary coughs and the first two indu
