In healthcare, RCP most commonly stands for Respiratory Care Practitioner, a licensed professional who specializes in treating patients with breathing difficulties and cardiopulmonary conditions. The term is largely interchangeable with “respiratory therapist” (RT), though some states and institutions use RCP as the formal title. Outside the United States, RCP can also refer to the Royal College of Physicians, a centuries-old medical organization in the UK, but in clinical job listings and hospital settings, it almost always means someone who manages your airway and lung care.
What Respiratory Care Practitioners Do
RCPs work across nearly every corner of a hospital, but their presence is most critical in intensive care units, emergency departments, and neonatal units. Their core job is keeping patients breathing, whether that means managing a ventilator for someone who can’t breathe on their own, drawing and analyzing blood samples to check oxygen and carbon dioxide levels, or assisting with bronchoscopy procedures that let physicians look inside the airways.
At the NIH Clinical Center, for example, respiratory care staff handle ventilator management, specialized gas therapies (like nitric oxide for pulmonary hypertension), hemodynamic monitoring, six-minute walk tests, and sputum inductions used to diagnose infections. These responsibilities make RCPs essential members of the critical care team, not support staff on the sidelines.
Outside the ICU, RCPs educate patients and families on managing chronic conditions like COPD and asthma at home, run pulmonary rehabilitation programs, and conduct diagnostic tests that help physicians understand how well a patient’s lungs are functioning. Many specialize in neonatal care, working with premature infants whose lungs haven’t fully developed.
Where RCPs Work
Hospitals employ the majority of respiratory care practitioners, particularly in critical care and emergency settings. But the profession extends well beyond hospital walls. RCPs also work in home health agencies, helping patients who depend on portable oxygen or home ventilators. Outpatient clinics, sleep laboratories, skilled nursing facilities, and physician offices all employ respiratory therapists as well. The pay varies by setting: hospital-based RCPs earned a median of about $78,300 in 2023, while those in skilled nursing facilities earned around $73,390.
Education and Certification
Becoming an RCP requires at minimum an associate degree from a respiratory therapy program accredited by the Commission on Accreditation for Respiratory Care (CoARC). That said, the field is shifting toward a bachelor’s degree as the standard, with many employers now preferring or requiring a four-year degree. CoARC accredits programs at the associate, bachelor’s, and master’s levels.
After graduating, candidates sit for the Therapist Multiple-Choice (TMC) Examination administered by the National Board for Respiratory Care. This single exam has two score thresholds. Hitting the lower cutoff earns you the Certified Respiratory Therapist (CRT) credential. Hitting the higher cutoff earns the CRT and makes you eligible to take the Clinical Simulation Examination, which leads to the Registered Respiratory Therapist (RRT) credential. The RRT is considered the higher-level certification and is increasingly expected by employers. Applicants must be at least 18 and hold a degree from an accredited program.
State licensure is a separate step. Each state has its own licensing board, and in California, for instance, the Respiratory Care Board defines the scope of practice as therapy, management, rehabilitation, diagnostic evaluation, and care of patients with conditions affecting the pulmonary system and related cardiopulmonary functions. RCPs practice under the supervision of a medical director.
Job Outlook and Pay
Respiratory therapy is one of the faster-growing healthcare professions. The Bureau of Labor Statistics projects 12 percent employment growth from 2024 to 2034, a rate described as “much faster than average.” An aging population with higher rates of chronic lung disease, plus continued demand for critical care expertise, drives that growth. The median annual pay reached $80,450 as of May 2024.
Other Meanings of RCP in Healthcare
If you encounter “RCP” in a British or international medical context, it likely refers to the Royal College of Physicians. Founded in 1518 under a charter from Henry VIII, the RCP is the oldest medical college in England. It focuses on improving patient care, setting clinical standards, and training physicians, particularly in internal medicine specialties. The Federation of the Royal Colleges of Physicians includes three UK colleges with international reach. This RCP is an institution, not a job title, so context usually makes the meaning clear.
In some clinical physiology circles, particularly in the UK, you may also see “RCCP” (Registration Council for Clinical Physiologists), a voluntary register for practitioners who perform diagnostic tests related to heart rhythm, lung function, hearing, and sleep. These clinical physiologists are a distinct group from respiratory therapists, though their work occasionally overlaps in pulmonary function testing.
