Respiratory therapists are specialized healthcare workers who help patients with breathing and heart problems. They work with people of all ages, from premature babies to elderly patients with chronic lung disease. According to the U.S. Bureau of Labor Statistics, this field is expected to grow much faster than the average for all occupations, making it a strong career choice for those interested in healthcare.
What Does a Respiratory Therapist Do?
Respiratory therapists perform a wide range of tasks. They interview patients, perform chest exams, and check the air in a patient's lungs. They also manage ventilators for patients who cannot breathe on their own and administer treatments like oxygen or aerosol medications. As the Bureau of Labor Statistics explains, they often work as part of a team with doctors and nurses to develop and adjust treatment plans.
Some respiratory therapists also work in home care settings. They visit patients at home to check equipment, teach patients how to use their devices, and ensure treatments are being followed correctly. This role is especially important for patients with chronic conditions like COPD or sleep apnea.
How to Become a Respiratory Therapist
To become a respiratory therapist, you typically need at least an associate's degree in respiratory therapy. Many employers prefer candidates with a bachelor's degree. According to the Kansas State Board of Healing Arts, all states require respiratory therapists to be licensed. This usually means passing a national exam from the National Board for Respiratory Care (NBRC).
Programs include courses in human anatomy, physiology, chemistry, microbiology, and pharmacology. Students also get hands-on training in clinical settings. After graduation, new therapists must pass exams to earn the Certified Respiratory Therapist (CRT) credential, and many go on to earn the Registered Respiratory Therapist (RRT) credential, which is often preferred by employers.
Work Environment and Job Outlook
Most respiratory therapists work in hospitals, especially in emergency rooms, intensive care units, and neonatal units. Others work in nursing homes, home health agencies, or outpatient clinics. The work can be physically demanding — therapists often stand for long periods and may need to lift or move patients.
The job outlook is strong. The Bureau of Labor Statistics projects employment will grow much faster than average due to an aging population and the rise of chronic respiratory conditions like COPD and asthma. This means more opportunities for new graduates.
Our Take: A Growing Field with Real Impact
Respiratory therapy is a career that combines hands-on medical care with direct patient interaction. In our view, it is an excellent option for people who want to work in healthcare but prefer a more focused role than nursing or medicine. The strong job growth and relatively short training path make it accessible. However, the work can be stressful and emotionally demanding, especially in critical care settings. For those who are ready for the challenge, it offers a stable and rewarding career.
