What Does a Respiratory Therapist Do?
If you have good interpersonal skills and you want to make an impact on someone’s life, consider a career as a respiratory therapist.
Respiratory therapists treat diseases of the lungs and airways. This includes chronic respiratory diseases like asthma, emphysema and sleep apnea but also includes emergency situations such as cardiac arrest. They work under the direction of a doctor.
They measure lung capacity and blood oxygen levels to set a baseline breathing ability and develop a treatment plan. Respiratory therapists perform chest physiotherapy on patients to remove mucus from their lungs, administer aerosol medications that help patients breathe more easily and connect patients who can’t breathe on their own to a ventilator.
Work environments can include pulmonary rehabilitation clinics, diagnostic laboratories, nursing homes and hospitals, where they work with other healthcare professionals.
According to the Bureau of Labor Statistics, this job is expected to grow 23% from 2020 to 2030, much faster than the average for all occupations.

Becoming a Respiratory Therapist: FAQs
What are the requirements to become a respiratory therapist?
All respiratory therapists must earn an associate degree in an accredited program. The Commission on Accreditation of Respiratory Care (CoARC) is one well-known accrediting program that approves programs offered at community colleges and technical schools. This short training window is one of the reasons why it's one of SkillPointe's highest-paying skilled jobs that don't require a bachelor's degree.
Some prerequisites, such as chemistry, may be required to enter any degree program.
Course work in any degree program will include human anatomy, physiology, pharmacology and diagnostic procedures in addition to supervised clinical work with patients. The clinical work allows students to learn how to care for patients under direct supervision and how to do patient assessments and create treatment programs.
What other qualifications do I need?
In addition to your degree program, you will need a license to practice. All states except Alaska require therapists to be licensed, but specific licensure rules vary by state. (See the license and certification section for specific details about your state’s requirements.) A background check is required in most states.
You may also have to pass a national or state exam. The National Board for Respiratory Care (NBRC) is the main certifying body for respiratory therapists. Through NBRC, candidates can earn a Certified Respiratory Therapist (CRT) credential or take additional exams to earn an advanced Registered Respiratory Therapist (RRT) credential. Respiratory therapists who work in states that don’t require these exams often take the exams anyway because some employers require them.
Because the field of respiratory therapy is dynamic, continuing education is often required. This may include competency tests and new skills.
How long does it take to become a respiratory therapist?
An associate degree takes two years.
Is there a demand for respiratory therapists?
Yes. According to the BLS, an average of 10,100 openings for respiratory therapists are projected each year from 2020 to 2030. An aging population and workers who move up and learn new skills or retire will keep demand in place.
