Clinical Best Practice Guideline



April 2022


This College of Respiratory Therapists of Ontario (CRTO or “the College”) Clinical Best Practice Guideline (CBPG) was developed by the Professional Practice Committee (PPC) of the CRTO in consultation with Council and other committees of the College, Members at large and staff.

The PPC is a non-statutory committee comprised of Registered Respiratory Therapists (RRT) and public members with a wide range of knowledge and experience from various practice areas across Ontario. This committee was formed by the CRTO in 2010 to focus specifically on the review and development of standards of practice directly related to the practice of Respiratory Therapy in Ontario. By having a standing committee of Respiratory Therapy leaders and experts from core areas of practice, and the ability to draw on additional expertise where necessary, the CRTO aims to ensure consistency in the review and development of publications in a timely fashion. The CRTO would like to acknowledge the work of the PPC, Members at large, and staff in the development of this new CBPG.
