This is the first of a three-part series written in collaboration with respiratory therapist Mark W. Mangus Sr., RRT, RPFT, FAARC, and Ryan Diesem, RRT.

One of the more hotly debated topics in the treatment of respiratory disease is supplemental oxygen use. Participants in the debate often include patients, clinicians, caretakers, suppliers, advocacy groups, and even politicians. In my experience, the information regarding when and how to use supplemental oxygen ranges in quality from the good, the bad, and in keeping with our western theme, the complete bull. It is my hope that I can help clear the air. That’s my third and final western pun. Thank you very much. I’ll be here all week.
