Respiratory Therapist Career Path: A Complete Guide

The respiratory therapist career path runs through a CoARC-accredited degree (usually a two-year associate or a bachelor's), the national board exams to earn the CRT and then the RRT credential, and a state license to practice. From there, therapists can specialize in critical care, neonatal/pediatric, or pulmonary diagnostics and move into lead, educator, or management roles.

Respiratory therapists are the clinicians who help patients breathe — managing ventilators in the ICU, treating asthma and COPD, responding to codes, and caring for newborns with underdeveloped lungs. It's a hands-on, credential-driven career with strong projected demand. If you're weighing it as a first career or a transition into healthcare, this guide maps the full path: education, certification, licensure, earnings outlook, and how to advance.

What a Respiratory Therapist Does

Respiratory therapists assess, treat, and monitor patients with breathing and cardiopulmonary disorders, working under a physician's direction. Day to day, the role can include administering oxygen and aerosol medications, managing mechanical ventilation, performing pulmonary function tests and arterial blood-gas analysis, responding to emergencies, and educating patients on managing chronic conditions like COPD and asthma. They work in hospitals (especially ICUs and emergency departments), neonatal units, sleep labs, home care, and pulmonary rehabilitation.

Step 1: Earn a CoARC-Accredited Degree

The educational foundation is a degree accredited by the Commission on Accreditation for Respiratory Care (CoARC). The most common entry point is an associate degree in respiratory therapy, which typically takes about two years. Accreditation matters: graduating from a CoARC-accredited program is what makes you eligible to sit for the national board exams.

Many therapists go on to earn — or start with — a bachelor's degree, which is increasingly preferred by employers and opens more doors into leadership, education, and specialized practice. Coursework blends anatomy, physiology, pharmacology, and cardiopulmonary science with extensive supervised clinical rotations.

Step 2: Pass the Board Exams (CRT, then RRT)

Certification is administered by the National Board for Respiratory Care (NBRC) and follows two levels:

• CRT (Certified Respiratory Therapist): the entry-level credential, demonstrating core competence in respiratory care.
• RRT (Registered Respiratory Therapist): the advanced credential, widely regarded as the profession's standard of excellence and required or strongly preferred for most hospital roles.

Most candidates also complete Basic Life Support (BLS) certification, and many add Advanced Cardiovascular Life Support (ACLS) or Pediatric Advanced Life Support (PALS) depending on their setting.

Step 3: Get Licensed in Your State

Nearly every U.S. state requires respiratory therapists to hold a state license to practice. Licensure generally requires graduation from an accredited program plus the CRT or RRT credential, and may include a background check and an application fee. Because requirements and renewal rules differ by state, confirm the specifics with your state's licensing board before and during your program — it's the step most likely to vary.

Salary and Job Outlook

According to the U.S. Bureau of Labor Statistics (BLS), respiratory therapy offers competitive pay and strong projected growth, with employment expected to expand much faster than the average for all occupations over the current decade — driven largely by an aging population and rising rates of chronic respiratory conditions. Entry-level earnings start lower and rise with experience, credentials, shift differentials, and specialization. Because figures are updated regularly, check the current numbers in the BLS Occupational Outlook Handbook (bls.gov) for the latest median wage and growth projection.

Advancing Your Respiratory Therapy Career

The RRT is a launchpad, not a ceiling. With experience, therapists can pursue specialty credentials through the NBRC and related bodies, including:

• ACCS (Adult Critical Care Specialty) for ICU-focused practice.
• NPS (Neonatal/Pediatric Specialist) for newborn and pediatric care.
• CPFT / RPFT for pulmonary function technology and diagnostics.
• SDS (Sleep Disorders Specialty) for sleep-medicine settings.

Beyond clinical specialties, paths open into lead therapist, clinical educator, department management, case management, medical-device sales, and roles in research or pulmonary rehabilitation. A bachelor's or master's degree accelerates the move into supervisory and educator tracks.

Where Respiratory Therapists Work

Respiratory care happens far beyond the hospital floor, and the setting shapes the day-to-day work and schedule:

• Hospitals — the largest employer, spanning emergency departments, general floors, and intensive care units, often on rotating shifts that include nights and weekends.
• Neonatal and pediatric units — caring for premature infants and children with respiratory conditions, frequently requiring the NPS credential.
• Sleep laboratories — conducting and analyzing studies for sleep-disordered breathing.
• Home health and durable medical equipment — setting up and managing home oxygen, ventilators, and CPAP, and educating patients and families.
• Pulmonary rehabilitation and outpatient clinics — supporting patients with chronic conditions through education and structured therapy.

This variety means a therapist who starts in acute care can later pivot to a more predictable outpatient or home-care schedule without leaving the profession.

Is Respiratory Therapy Right for You?

The career suits people who are calm under pressure, comfortable with technology and patient contact, and motivated by tangible impact — you often see a patient breathe easier within minutes of an intervention. It also asks for physical stamina, the willingness to work some nights, weekends, and holidays in hospital settings, and the discipline to maintain credentials and continuing education over a career. If steady demand, a clear credentialing ladder, and hands-on clinical work appeal to you, it's a field worth serious consideration. As with any move into healthcare, talk to working respiratory therapists and tour a program's clinical sites before committing.

Frequently Asked Questions

How long does it take to become a respiratory therapist? Typically about two years for a CoARC-accredited associate degree, plus time to pass the board exams and obtain state licensure. A bachelor's path takes about four years.

What's the difference between a CRT and an RRT? The CRT is the entry-level credential; the RRT is the advanced credential and is considered the profession's standard. Most hospitals prefer or require the RRT.

Do I need a license to work as a respiratory therapist? In nearly every state, yes. Licensure generally requires an accredited degree and national certification — check your state board for exact requirements.

Is respiratory therapy a good career? It offers strong projected demand, competitive pay, and clear advancement options. The BLS projects faster-than-average growth, though work can involve nights, weekends, and high-acuity settings.

Can I become a respiratory therapist without a four-year degree? Yes. A two-year CoARC-accredited associate degree is the most common entry point, though a bachelor's broadens your opportunities and advancement potential.

What does a respiratory therapist resume need? Lead with your credentials (RRT/CRT, BLS), your CoARC degree, and clinical settings you've trained in, then quantify your experience with ventilator management, patient loads, and specialty exposure.

Respiratory therapy rewards people who want hands-on clinical work with a clear, credential-based ladder. Earn the CoARC degree, pass the NBRC exams to reach RRT, get licensed, and you'll be positioned in a high-demand field with room to specialize and lead. Verify current requirements and earnings through CoARC, the NBRC, and the BLS before you commit.
