Respiratory Therapy


Respiratory Therapists practice under a medical doctor and are responsible for:

  • Diagnosing lung and breathing disorders and recommending treatment methods.
  • Interviewing patients and doing chest physical exams to determine what kind of therapy is best for their condition.
  • Consulting with physicians to recommend a change in therapy, based on your evaluation of the patient.
  • Analyzing breath, tissue, and blood specimens to determine levels of oxygen and other gases.
  • Managing ventilators and artificial airway devices for patients who can’t breathe normally on their own.
  • Responding to Code Blue or other urgent calls for care.
  • Educating patients and families about lung disease so they can maximize their recovery.   (From “Be an RT” at
