Course Abstract

Vocal cord dysfunction (VCD) is characterized as an abnormal closing of the vocal cords during the inspiration producing airflow obstruction and frequently mimics asthma. Spirometry, specifically flow volume loops can be used by the Speech Language Pathologist to diagnose and treat patients with VCD. This course will teach the user how to use the spirometer to take and interpret respiratory measures in VCD patients for diagnosis and treatment.
