ODwyers method, named after Dr. Charles E. ODwyer, is primarily used in the field of physiotherapy to treat certain respiratory conditions. However, synonymous terms are often used to refer to this technique. One alternative name is the "cough-assist method", as it involves helping patients generate strong coughs to clear their airways. It is also known as "forced exhalation technique", as it necessitates a controlled, forceful exhalation. Additionally, some healthcare professionals may refer to it as the "airway clearance technique", highlighting its purpose of promoting efficient airway clearance. These synonyms all describe the same therapeutic technique developed by ODwyer, serving as a testament to its importance and widespread acceptance in respiratory care.
