Dosimetrist Career Guide: Role, Salary, Education, and How to Get Started
11 Apr, 2026
If you've been researching healthcare careers and stumbled upon the term respiratory therapist — even if you initially searched for "respirotry therapist" like so many others do — you've landed on one of the most in-demand, personally fulfilling, and financially stable career paths in modern medicine. I've spent years helping healthcare professionals find their ideal roles through healthcareers.app, and I can tell you with confidence that respiratory therapy consistently ranks among the top allied health professions for job satisfaction, growth potential, and meaningful patient impact.
In this comprehensive guide, I'll walk you through everything you need to know about becoming a respiratory therapist — from education requirements and certification pathways to salary expectations and long-term career growth. I'll also explore how this role compares to and intersects with other healthcare positions like nursing aids and specialized fields such as cardiovascular perfusion training. Whether you're a high school student mapping out your future, a career changer exploring healthcare, or a current healthcare worker looking to advance, this guide is built for you.
Respiratory therapists are specialized healthcare professionals who evaluate, treat, and care for patients with breathing disorders and cardiopulmonary conditions. Their work touches virtually every department in a hospital — from the neonatal intensive care unit where they help premature babies breathe to the emergency room where they assist patients in acute respiratory distress.
What I find remarkable about this profession is its blend of technical expertise and compassionate patient care. Respiratory therapists don't just operate machines — they literally help people breathe, which is about as fundamental to life as healthcare gets.
One of the most common questions we receive on healthcareers.app is about the educational pathway to becoming a respiratory therapist. Here's the step-by-step breakdown.
To become a licensed respiratory therapist, you'll need at minimum an associate degree in respiratory therapy from a program accredited by the Commission on Accreditation for Respiratory Care (CoARC). However, I strongly recommend pursuing a bachelor's degree if possible. The industry is trending toward requiring a bachelor's as the entry-level standard, and many employers already prefer or require it for advancement into leadership roles.
Typical coursework includes anatomy and physiology, pharmacology, pathophysiology, cardiopulmonary diagnostics, mechanical ventilation, and clinical rotations in hospital settings. Most programs take two years for an associate degree and four years for a bachelor's degree.
After graduating from an accredited program, you'll need to pass the Therapist Multiple-Choice (TMC) Examination administered by the National Board for Respiratory Care (NBRC). Scoring at the higher cut score on the TMC qualifies you to take the Clinical Simulation Examination (CSE), which earns you the prestigious Registered Respiratory Therapist (RRT) credential.
While the Certified Respiratory Therapist (CRT) credential exists as the entry-level designation, I always advise candidates to aim for the RRT. The vast majority of employers prefer it, and it opens doors to higher salaries and specialized positions.
Nearly all states require respiratory therapists to hold a valid state license. Requirements vary by state but generally include holding an NBRC credential and completing continuing education units on a regular cycle.
Let's talk numbers — because I know that's what many of you are here for, and the news is genuinely encouraging.
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 occupational data. The top 10 percent of earners in the field made over $100,000 annually, particularly those working in specialty hospitals, metropolitan areas with high costs of living, or in travel and contract positions.
Several factors influence where you fall on the salary spectrum:
The Bureau of Labor Statistics projects that employment for respiratory therapists will grow by 13 percent from 2022 to 2032, which is much faster than the average for all occupations. This growth is driven by an aging population with increasing rates of chronic respiratory conditions, the lingering cardiopulmonary effects of COVID-19, and the growing recognition of respiratory therapists as essential members of critical care teams.
We track hiring trends closely at healthcareers.app, and I can confirm that respiratory therapist job postings have remained consistently strong across all regions of the United States. Employers are actively competing for qualified candidates, which gives job seekers meaningful leverage in salary negotiations.
I frequently help candidates weigh respiratory therapy against other healthcare pathways. Let me address two common comparisons that come up regularly.
Nursing aids (also called certified nursing assistants or CNAs) play a vital role in patient care, providing hands-on assistance with daily activities like bathing, feeding, mobility, and vital sign monitoring. Many people begin their healthcare careers as nursing aids because the barrier to entry is relatively low — certification programs often take just 4-12 weeks.
However, the career trajectories and compensation levels are quite different. According to the Bureau of Labor Statistics, the median annual wage for nursing assistants is approximately $35,760 — less than half of what respiratory therapists earn. If you're currently working as a nursing aid and considering your next move, respiratory therapy offers a substantial step up in both compensation and clinical scope.
That said, I've seen many successful respiratory therapists who started as nursing aids. The bedside experience, patient communication skills, and comfort in clinical environments that nursing aids develop provide an excellent foundation for respiratory therapy school. If this describes your situation, I encourage you to explore the pathway — your existing experience is a genuine asset.
Another interesting intersection I want to highlight involves cardiovascular perfusion training. Cardiovascular perfusionists are highly specialized professionals who operate heart-lung bypass machines during open-heart surgery and other procedures requiring cardiopulmonary support. While this is a distinct profession from respiratory therapy, the foundational knowledge overlaps significantly — both require deep understanding of cardiopulmonary physiology, gas exchange, hemodynamics, and critical care equipment.
Some respiratory therapists pursue cardiovascular perfusion training as an advanced career move. Perfusion programs typically require a bachelor's degree and relevant clinical experience, which respiratory therapists often possess. The American Society of ExtraCorporeal Technology (AmSECT) accredits perfusion education programs, and graduates can earn competitive salaries that often exceed $130,000 annually.
If you're drawn to both respiratory therapy and the surgical/interventional side of cardiopulmonary care, starting as a respiratory therapist and later pursuing cardiovascular perfusion training can be a powerful long-term career strategy. It's one of the more advanced pathways I recommend to ambitious candidates on our platform.
One of the things I love about respiratory therapy is that it doesn't have to be a static career. There are numerous specialization pathways that allow you to grow, earn more, and focus on the patient populations that inspire you most.
With a bachelor's or master's degree, respiratory therapists can advance into management, education, and research roles. Positions like respiratory therapy department director, clinical educator, or respiratory care program director offer six-figure salaries and the opportunity to shape the next generation of practitioners. The National Institutes of Health (nih.gov) also funds research related to respiratory health, and respiratory therapists with advanced degrees can participate in clinical research that advances the entire field.
Based on years of connecting healthcare employers with candidates through healthcareers.app, here are my most actionable tips for new graduates entering the respiratory therapy job market.
While some employers will hire CRT holders with the expectation that they'll earn the RRT within a set timeframe, having the RRT credential from day one makes you significantly more competitive. It signals commitment and competence to hiring managers.
The relationships you build during clinical rotations are invaluable. Many respiratory therapists receive job offers from the facilities where they completed their training. Be professional, enthusiastic, and proactive during every rotation — treat it as an extended job interview.
Most new graduates start on less desirable shifts. Embrace this — you'll gain more hands-on experience during nights when staffing is leaner, and you'll often qualify for shift differentials that boost your starting income.
Create a professional profile on healthcareers.app and keep your resume updated with specific clinical competencies, equipment experience, and any relevant certifications. Highlight your ventilator management experience specifically, as this remains one of the most sought-after skills.
Teaching hospitals expose you to the widest variety of cases, advanced technology, and continuing education opportunities. The experience you gain in your first two to three years will shape the rest of your career.
The timeline depends on your educational path. An associate degree program typically takes two years, while a bachelor's degree takes four years. After graduation, you'll need additional time to pass your board exams and obtain state licensure. In total, most people can become fully credentialed respiratory therapists in two to four years after starting their education. If you're transitioning from a related role — such as working as nursing aids or other clinical support staff — you may be able to transfer some prerequisite coursework, potentially shortening the timeline.
Absolutely. With projected job growth of 13 percent over the next decade according to the Bureau of Labor Statistics, an aging population with increasing respiratory care needs, and median salaries approaching $80,000, respiratory therapy is one of the strongest healthcare career choices available. The COVID-19 pandemic also permanently elevated the visibility and perceived importance of respiratory therapists within healthcare systems, which has translated into better staffing ratios, higher compensation, and greater professional respect.
Yes, and it's actually one of the more natural transition pathways in allied health. Respiratory therapists who pursue cardiovascular perfusion training bring valuable knowledge of cardiopulmonary physiology, ventilator management, and critical care protocols. Most perfusion programs require a bachelor's degree and clinical experience in a related field, both of which experienced respiratory therapists typically possess. It's an advanced move that can significantly increase your earning potential.
The Certified Respiratory Therapist (CRT) is the entry-level credential earned by passing the TMC examination at the lower cut score. The Registered Respiratory Therapist (RRT) is the advanced credential earned by passing the TMC at the higher cut score and then passing the Clinical Simulation Examination. The RRT is the industry standard and is preferred or required by the majority of employers. I always recommend targeting the RRT from the start of your education.
Not at all. While hospitals are the primary employer, respiratory therapists also work in outpatient clinics, physician offices, skilled nursing facilities, home health agencies, sleep labs, pulmonary rehabilitation centers, and even pharmaceutical and medical device companies. Some respiratory therapists work in education, research, or as clinical specialists for equipment manufacturers. The versatility of the profession is one of its greatest strengths.
