Respiratory Therapist (RT)/Certified (CRT)/Registered (RRT)

  • Respiratory Therapist (RT)/Certified (CRT)/Registered (RRT)

Respiratory therapists, also referred to as respiratory care practitioners, provide care, treatment, diagnosis, and rehabilitation for patients with breathing problems. Disorders such as asthma and emphysema, and emergency care for victims of stroke, heart failure, drowning, or shock are but a few of the types of problems seen by respiratory therapists.

Work Activities/Work Locations

Respiratory therapists may work in hospitals, nursing homes, home health agencies, or private companies. They work with patients of all ages – from premature infants to elderly patients. Respiratory therapists work under the supervision of a physician. Respiratory therapists are trained to evaluate a patient’s condition and recommend therapies for treatment. They operate breathing devices to test the function of the lungs and they are trained to monitor their patient’s responses to therapy by checking vital signs and performing blood tests. Respiratory therapists teach proper breathing exercises to aid in a patient’s recovery. They evaluate and maintain patient charts. Respiratory therapists typically work 35-40 hours a week, which may include evenings and weekends. Because of the nature of their work, respiratory therapists may experience emergency type situations, and often perform duties while standing. 

Getting Started

High school students should study health, biology, mathematics, chemistry and physics. Accredited training programs for respiratory therapists may either be a 2-year program leading to an associate degree or a 4-year program leading to a bachelor’s degree. Course work focuses on mathematics, human anatomy and physiology, chemistry, physics, microbiology, and career specific classes. Upon completion of a 2-year or 4-year accredited program, graduates must receive a license as a respiratory care practitioner. They may take the exam to become a Certified Respiratory Therapist (CRT). Wisconsin mandates a license to practice, such as a CRT. If a CRT meets education and experience requirements, and passes a separate examination, they are eligible to become a Registered Respiratory Therapist (RRT).
