Dosimetrist Career Guide: Role, Salary, Education, and How to Get Started
11 Apr, 2026
If you've been searching for information about becoming a respiratory therapist, you've landed in exactly the right place. I've spent years helping healthcare professionals navigate their career paths, and I can tell you with confidence that respiratory therapy is one of the most in-demand, emotionally fulfilling, and financially stable allied health careers available today. Whether you're a recent graduate exploring allied health pre-professional jobs or a seasoned professional considering a career pivot, this comprehensive guide will walk you through everything you need to know — from education and licensing requirements to salary expectations and job outlook.
We built healthcareers.app because we believe every healthcare worker deserves clear, honest guidance on their career journey. So let's dive deep into what it truly takes to become a respiratory therapist, what your day-to-day life will look like, and how to position yourself for long-term success in this critical field.
A respiratory therapist (RT) is a specialized healthcare professional who evaluates, treats, and cares for patients with breathing disorders and cardiopulmonary conditions. These range from chronic diseases like asthma, COPD, and cystic fibrosis to acute emergencies like trauma, heart attacks, and premature births where newborns struggle to breathe independently.
On any given shift, a respiratory therapist might:
I've spoken with hundreds of respiratory therapists over the years, and the theme that consistently emerges is the profound sense of purpose they feel. When you help someone take their first unassisted breath after being on a ventilator for weeks, or when you calm an asthmatic child through a terrifying episode — that's the kind of impact that defines this career.
The minimum educational requirement to enter the respiratory therapy field is an associate's degree in respiratory therapy or respiratory care from a program accredited by the Commission on Accreditation for Respiratory Care (CoARC). These programs typically take two years to complete and include both classroom instruction and clinical rotations in hospital settings.
Coursework generally covers human anatomy and physiology, pharmacology, cardiopulmonary pathology, patient assessment techniques, mechanical ventilation, and neonatal and pediatric respiratory care. Clinical rotations give you hands-on experience in intensive care units, emergency departments, pulmonary rehabilitation centers, and sleep disorder labs.
While an associate's degree will qualify you for entry-level positions, I strongly recommend considering a bachelor's degree in respiratory therapy — especially if you're early in your career planning. The American Association for Respiratory Care (AARC) has been advocating for the bachelor's degree to become the standard entry-level credential, and many employers are already giving preference to candidates with a four-year degree.
A bachelor's program provides deeper coursework in leadership, research, disease management, and advanced patient care. If you eventually want to move into management, education, or specialized clinical roles, a bachelor's or even a master's degree will open those doors significantly wider.
Obtaining your healthcare professional license is one of the most critical steps in your respiratory therapy career. Every state requires respiratory therapists to hold a valid license or permit to practice, though specific requirements vary by state.
After graduating from an accredited program, you'll need to pass national credentialing exams administered by the National Board for Respiratory Care (NBRC). There are two primary credentials:
Once you've earned your NBRC credential, you'll apply for a state-specific healthcare professional license through your state's licensing board. Requirements typically include proof of education, passing exam scores, a background check, and a licensing fee. Most states require license renewal every one to two years, which involves completing continuing education credits.
I always advise candidates on our platform to research their specific state's requirements early in the process. Some states have additional stipulations, and you don't want licensing delays to hold you back from starting your dream job.
For those who want to stand out in a competitive job market, the NBRC also offers specialty credentials:
These specialty certifications demonstrate advanced expertise and can lead to higher pay and more specialized roles.
Let's talk numbers — because I know that's a major factor in career decisions, and it should be.
According to the Bureau of Labor Statistics (bls.gov), the median annual wage for respiratory therapists was approximately $77,960 as of their most recent data. The top 10 percent of earners in this field made more than $102,000 per year, while entry-level positions typically start around $57,000 to $62,000 depending on location and facility type.
Several factors influence your earning potential:
The job outlook is equally encouraging. The Bureau of Labor Statistics projects employment for respiratory therapists to grow by 13 percent from 2022 to 2032 — much faster than the average for all occupations. This growth is driven by an aging population with higher incidences of respiratory conditions, the ongoing prevalence of chronic lung diseases, and the lessons learned during the COVID-19 pandemic about the critical importance of respiratory care professionals.
If you're still in school or exploring whether respiratory therapy is right for you, there are several allied health pre-professional jobs that can help you build relevant experience and confirm your career direction before committing to a full respiratory therapy program.
Working as a patient care technician (PCT) or certified nursing assistant (CNA) gives you direct patient care experience. You'll learn how to communicate with patients, work within a healthcare team, and become comfortable in clinical environments — all skills that transfer directly to respiratory therapy.
Medical assistant roles in pulmonology or primary care offices expose you to respiratory conditions, pulmonary function testing, and patient education. This is an excellent way to see the respiratory side of healthcare up close.
EMT experience is incredibly valuable for aspiring respiratory therapists. You'll develop airway management skills, learn to work under pressure, and gain a deep appreciation for the respiratory system's role in emergency medicine.
Many hospitals allow volunteers or interns to shadow respiratory therapy departments. I always encourage candidates on healthcareers.app to seek out these opportunities. Even a few weeks of observation can solidify your career decision and give you talking points for program interviews.
Sleep technology positions involve monitoring patients during sleep studies and working closely with respiratory therapists who interpret results and manage sleep-disordered breathing. It's a natural stepping stone into the RT field.
According to the National Institutes of Health (nih.gov), respiratory diseases remain among the leading causes of death and disability worldwide, which underscores the growing need for well-trained respiratory therapists and the importance of building a strong pre-professional foundation in this area.
One of the aspects I love most about respiratory therapy is the diversity of work settings available. Here's where you might find yourself:
Competition for the best respiratory therapy positions can be stiff, especially at prestigious hospitals and specialized facilities. Here are my top recommendations for making yourself an irresistible candidate:
I think it's helpful to paint a realistic picture of what your workday might look like. While every shift is different, here's a typical 12-hour hospital shift:
6:45 AM: You arrive and receive report from the night shift respiratory therapist. You review your patient assignments, which include three ventilator patients in the ICU, two post-surgical patients requiring bronchial hygiene, and several floor patients needing nebulizer treatments.
7:30 AM: You begin ICU rounds with the medical team, discussing ventilator weaning plans, ABG results, and any overnight changes in your patients' conditions.
8:00 AM – 12:00 PM: You administer treatments, adjust ventilator settings based on physician orders and clinical assessment, draw arterial blood gases, perform a spontaneous breathing trial on a patient being weaned from the ventilator, and respond to a rapid response call on a medical-surgical floor where a patient is experiencing acute respiratory distress.
12:00 PM: A quick lunch — if you're lucky.
1:00 PM – 5:00 PM: You continue treatments, educate a newly diagnosed COPD patient on inhaler technique, assist with an intubation in the emergency department, and document everything meticulously in the electronic health record.
5:00 PM – 7:00 PM: You complete end-of-shift treatments, update care plans, and give report to the incoming night shift therapist.
It's demanding, fast-paced, and often emotionally intense. But every respiratory therapist I've talked to says the same thing: there's nothing quite like this career.
It typically takes two years to earn an associate's degree in respiratory therapy and become eligible for credentialing exams. A bachelor's degree takes four years. After graduation, you'll need to pass the NBRC exams and obtain your state healthcare professional license before you can begin practicing — a process that usually takes a few additional weeks to months depending on your state.
Absolutely. With a projected 13 percent growth rate according to the Bureau of Labor Statistics, a median salary approaching $78,000, and increasing recognition of the profession's importance following the COVID-19 pandemic, respiratory therapy offers exceptional job security and growth potential. It's one of the strongest allied health career paths available today.
The Certified Respiratory Therapist (CRT) is the entry-level credential, while the Registered Respiratory Therapist (RRT) is the advanced credential. Both are issued by the National Board for Respiratory Care. The RRT requires passing the TMC exam at a higher cut score and completing the Clinical Simulation Examination. Most employers strongly prefer or require the RRT credential, and it typically leads to higher earning potential.
Yes. Respiratory therapists can pursue specialty certifications in adult critical care, neonatal and pediatric care, sleep disorders, and pulmonary function technology. Specialization allows you to focus on the patient populations and clinical areas you're most passionate about, while also increasing your marketability and salary potential.
Excellent stepping-stone positions include patient care technician, certified nursing assistant, medical assistant in a pulmonology office, EMT, sleep lab technician, and hospital volunteer or intern in a respiratory therapy department. These roles build foundational clinical skills and help confirm your interest in the field before you invest in a respiratory therapy program.
Becoming a respiratory therapist is one of the most meaningful career decisions you can make in healthcare. You'll be the person patients depend on during some of their most vulnerable moments — when every breath matters. The combination of strong job growth, competitive compensation, diverse work environments, and the sheer human impact of the work makes this an extraordinary career path.
Whether you're exploring allied health pre-professional jobs to test the waters, working through your education and credentialing, or actively searching for your first or next respiratory therapist position, I encourage you to take the next step today. Research accredited programs in your area, connect with practicing respiratory therapists, and start building the foundation for a career that will challenge and reward you for decades to come.
