It can be argued that nothing is more important than breath. Which is why so many are drawn to a career as a respiratory therapist. Respiratory therapists help patients breathe better, taking care of patients suffering from chronic or acute illnesses like asthma or pneumonia.
Learn how to become a respiratory therapist, what to look for in respiratory therapy training, and more about this exciting health care career.
Why Become a Respiratory Therapist?
Respiratory therapists work in a variety of medical settings helping patients work on breathing problems. According to the U.S. Bureau of Labor Statistics (BLS) nationwide employment of respiratory therapists is projected to grow 21% from 2018 to 2028, much faster than the average for all occupations.1
According to the BLS, as middle-age and older populations age, there will likely be an increased incidence of respiratory conditions such as pneumonia, chronic obstructive pulmonary disease (COPD), and other disorders that can permanently damage the lungs or restrict lung function. Additionally, as hospitals continue to fight to lower readmission rates, there may be greater demand for respiratory therapists in outpatient settings such as nursing homes and doctor’s offices.
Overall, the advances in medicine in preventing and detecting disease, improved medications, and more sophisticated treatments will also increase the demand for respiratory therapists. Also, as smoking, pollution, and respiratory illnesses continue to be prevalent, there should be more demand for therapists to treat these issues, according to the BLS.
What Does a Respiratory Therapist Do?
Respiratory therapists care for those who have trouble breathing. Some of the most common chronic respiratory illnesses are chronic obstructive pulmonary disease (COPD), asthma, occupational lung diseases and pulmonary hypertension. According to the World Health Organization’s most recent data, more than 339 million people had asthma globally4 and there were 251 million cases of COPD globally in 20165.
Respiratory therapists work with common respiratory patients like those described above, as well as everyone from premature infants with undeveloped lungs to elderly patients who have diseased lungs. Respiratory therapists also provide emergency care to patients suffering from heart attacks, drowning, or shock, according to the BLS.6
Some common job duties of a respiratory therapist include:
- Interviewing and examining patients with breathing or cardiopulmonary disorders
- Consulting with physicians to develop patient treatment plans
- Performing diagnostic tests, such as measuring lung capacity
- Treating patients by using a variety of methods, including chest physiotherapy and aerosol medications
- Monitoring and recording patients’ progress
- Teaching patients how to take medications and use equipment, such as ventilators
Respiratory therapists use a variety of tools to measure lung capacity, as well as bloodwork to determine oxygen levels. They also can provide physiotherapy on patients to remove mucus from their lungs and make it easier for them to breathe. Removing mucus is necessary for patients suffering from lung diseases, such as cystic fibrosis, and involves the therapist vibrating the patient’s rib cage, often by tapping the patient’s chest while the patient coughs.
Where Do Respiratory Therapists Work?
Respiratory therapists can work in a variety of medical settings. While the BLS reports that 81% of respiratory therapists worked in either state, local or private hospitals,8 they are not limited to there.
According to the American Association of Respiratory Care, respiratory therapists can be found in:9
- Intensive care units
- Emergency rooms
- Newborn and pediatric units
- Operating rooms and surgical suites
- In-home care settings
- Sleep laboratories
- Smoking cessation programs
- Asthma education programs
- Physicians’ offices
- Skilled nursing facilities
All of these settings will see respiratory therapists working to help people breathe easier, through lifesaving procedures like ventilation or everyday pulmonary therapy.
