Respiratory Therapist Roles & Work Settings
A respiratory therapy credential opens doors well beyond the hospital floor. This guide surveys the settings RTs work in and the roles they grow into, from bedside acute care to the sleep lab, the transport team, education, and management.

Overview
Respiratory therapists practice across the full continuum of care — from the emergency department and adult ICU to the NICU, the sleep lab, the home, and the classroom. The CRT (Certified Respiratory Therapist) and RRT (Registered Respiratory Therapist) credentials, awarded by the NBRC, are portable across these settings. Advancement typically involves adding specialty credentials, pursuing graduate education, or stepping into leadership and education roles.
Understanding the breadth of RT practice helps clinicians plan intentional careers and helps students appreciate the scope of the profession before choosing a first position.
Key Concepts
RT practice spans hospital and non-hospital environments. Certain settings are paired with specific NBRC specialty credentials that signal advanced competency in that area. The table below maps each major setting to the work RTs perform and the credentials most relevant to that setting.
| Setting | What RTs Do | Relevant Credential |
|---|---|---|
| Acute care (general floors & ED) | Oxygen delivery, aerosol therapy, assessment, airway management, emergency response and codes | CRT or RRT |
| Critical care (adult ICU) | Mechanical ventilation management, ABG analysis, ventilator weaning, ECMO support | RRT; ACCS for advanced ICU roles |
| Neonatal/pediatric (NICU/PICU) | Neonatal ventilation, neonatal resuscitation, surfactant administration, pediatric airway management, transport | RRT; NPS for specialty focus |
| Sleep medicine (sleep lab) | Polysomnography, CPAP/BiPAP titration, patient education on PAP therapy | RRT; SDS for sleep specialty |
| Pulmonary function / diagnostics (PFT lab) | Spirometry, lung volume measurement, diffusion capacity (DLCO), bronchoprovocation testing | CPFT or RPFT |
| Home care / durable medical equipment | Home oxygen setup, home ventilator management, CPAP/BiPAP initiation, patient and family education, follow-up | CRT or RRT |
| Patient transport (ground & air) | Critical-care transport, airway management, portable ventilation, hemodynamic monitoring during transfer | RRT; transport team certification varies by program |
| Education (RT programs) | Didactic instruction, clinical education, curriculum development, program direction | RRT; graduate degree typically required for program director |
| Management / leadership | Department supervision, staffing, budgeting, quality improvement, strategic planning | RRT; graduate education common for director-level roles |
| Emerging roles | ECMO specialist, clinical research, industry/medical device clinical education, health informatics | RRT; role-specific training or certification |
Advancing a Career
Career growth in respiratory therapy typically follows one of three paths — or a combination of all three.
- Clinical ladder. Most departments have a structured ladder: staff RT to senior or charge RT, then to supervisor, manager, and director. Each step usually requires demonstrated clinical competency, years of experience, and often a specialty credential or additional education.
- Specialization through credentials. NBRC specialty credentials — ACCS for adult critical care, NPS for neonatal/pediatric practice, SDS for sleep, CPFT/RPFT for pulmonary diagnostics — signal advanced competency and can unlock higher-acuity or niche positions. The ACCS and NPS require the RRT; the SDS and the pulmonary function credentials have pathways open to the CRT.
- Graduate education. A master’s or doctoral degree in respiratory care, healthcare administration, nursing practice, or a related field is increasingly expected for program director, department director, and research roles. CoARC (Commission on Accreditation for Respiratory Care) sets educational standards for RT programs, and faculty positions generally require graduate-level preparation.
Non-bedside paths — education, management, industry, informatics, and research — are viable and growing. RTs who move into medical device clinical education or health informatics often draw on their clinical foundation to bridge the gap between technology and patient care.
Common Pitfalls
- Assuming RT means only the hospital floor. Many new graduates default to acute care without exploring sleep medicine, pulmonary diagnostics, home care, or transport — settings that may offer better work-life balance or a stronger fit for their interests.
- Not pursuing the credential that unlocks a target setting. An RT interested in ICU careers who skips the ACCS, or one targeting neonatal care who does not pursue the NPS, may find advancement limited compared to peers who hold the relevant specialty credential.
- Overlooking non-bedside paths. Education, management, industry, and informatics roles leverage RT clinical expertise in ways that do not require shift work. Dismissing these paths early can close off career options later.
Key Takeaways
- The RT credential spans acute care, the ICU, the NICU/PICU, sleep medicine, pulmonary function diagnostics, home care, patient transport, education, and leadership.
- NBRC specialty credentials — ACCS, NPS, SDS, CPFT/RPFT — unlock higher-acuity and niche settings; the ACCS and NPS require the RRT, while the SDS and PFT credentials are open to the CRT.
- Graduate education is increasingly expected for program director, department director, and research positions.
- Non-bedside roles in education, management, industry, and informatics are viable career paths that draw on clinical RT expertise.
- Career planning benefits from early awareness of the full scope of RT practice — beyond the hospital floor.
FAQ
Where do most respiratory therapists work?
Most RTs begin their careers in hospital acute care or critical care settings, but the credential is portable across many environments — sleep labs, pulmonary function labs, home care agencies, ground and air transport teams, educational programs, and management roles. Hospitals employ the largest share of RTs, yet non-hospital positions are growing.
Which credentials help for ICU, NICU, or sleep lab roles?
The RRT (Registered Respiratory Therapist) credential is the common starting point. For adult critical care the ACCS (Adult Critical Care Specialist) credential offered by the NBRC recognizes advanced ICU competency. For neonatal/pediatric care the NPS (Neonatal/Pediatric Specialist) credential applies. For sleep medicine the SDS (Sleep Disorders Specialist) credential is relevant. These are specialty credentials offered by the NBRC; the ACCS and NPS require the RRT, while the SDS is open to the CRT or RRT.
Do respiratory therapists work outside of hospitals?
Yes. RTs work in home care and durable medical equipment companies (home oxygen, home ventilators, CPAP/BiPAP), skilled nursing facilities, outpatient pulmonary rehabilitation programs, sleep centers, PFT labs, air and ground transport services, respiratory therapy education programs, and in industry roles such as clinical sales and clinical education for medical device manufacturers.
How can a respiratory therapist advance their career?
A common path is a clinical ladder: staff RT to senior or charge RT, then into supervisory and management roles (supervisor, manager, director). Specialization through NBRC specialty credentials (ACCS, NPS, SDS, CPFT/RPFT) opens higher-acuity or niche settings. Graduate education — a master’s or doctoral degree in respiratory care, healthcare administration, or education — is typically required for program director and senior leadership positions.
