Respiratory Therapist Careers: Credentials, Settings, and Contract Work

Respiratory Therapist Careers: Credentials, Settings, and Contract Work

Respiratory therapists are the clinicians hospitals call when a patient stops breathing well enough to wait. RTs manage ventilators, assist with intubation, draw and interpret arterial blood gases, run nebulizer and airway clearance therapy, and stand on rapid response and code teams. In a 300-bed hospital, a night shift RT may cover the ICU, the emergency department, and the floors at the same time, which is why the role carries both real autonomy and real pressure.

The career path is shorter than most people expect and the pay scales faster than most allied health roles once you add credentials. This guide covers what respiratory therapists actually do across settings, the credentialing ladder from CRT to RRT, honest pay ranges for staff, per diem, and travel work, and why respiratory season pushes contract rates higher than any other time of year.

What Respiratory Therapists Do Across Settings

Respiratory therapists manage the airway and the ventilator, and the specific mix of work changes sharply depending on where you practice. An adult ICU RT spends the shift on vent management, weaning trials, and code coverage. A NICU RT spends it on surfactant administration, high-frequency oscillatory ventilation, and neonatal transports. A long-term care RT spends it on trach care, chronic vent patients, and teaching aides how to spot early distress. Same license, very different days.

Understanding those differences matters before you commit to a setting, because the skills you build in the first three years determine which contracts you can take later.

• Acute care hospitals: ventilator management, intubation assistance, ABG draws and interpretation, rapid response and code team response, bronchoscopy support

• NICU and pediatrics: neonatal resuscitation, HFOV and nitric oxide, surfactant delivery, transport teams

• Long-term care and subacute: chronic ventilator and tracheostomy management, weaning programs, staff education

• Sleep labs and pulmonary function: diagnostic testing, CPAP and BiPAP titration, spirometry

• Home care and durable medical equipment: patient teaching, equipment setup, follow-up assessment

Credentials: The Path From Student to RRT

To practice as a respiratory therapist in the United States you need a degree from a CoARC-accredited respiratory care program, a National Board for Respiratory Care credential, and a state license. Most RTs enter through a two-year associate degree, and a growing number of hospitals prefer or require a bachelor degree for leadership and specialty roles.

CRT and RRT

The NBRC uses one exam sequence with two outcomes. Passing the Therapist Multiple-Choice exam at the lower cut score earns the Certified Respiratory Therapist credential. Passing at the higher cut score qualifies you to sit for the Clinical Simulation Exam, and passing that earns the Registered Respiratory Therapist credential. Go for the RRT. Most acute care hospitals, and nearly every ICU assignment, list RRT as a requirement rather than a preference, and per diem and travel contracts almost always specify it.

State Licensure

Nearly every state licenses respiratory therapists separately, and there is no broad multi-state compact the way nursing has one. If you plan to travel, start license applications early. Some states process in two weeks, others take six to eight, and a slow license is the most common reason a travel RT misses a start date. Keeping licenses active in two or three neighboring states is a practical advantage that recruiters notice.

Pay: Staff Versus Per Diem Versus Travel

Staff respiratory therapists generally earn between $58,000 and $92,000 per year, which works out to roughly $28 to $44 per hour depending on market, experience, and shift differential. Metro hospitals on the West Coast and in the Northeast sit at the top of that band. Rural and Southern markets sit at the bottom. Night and weekend differentials typically add $3 to $8 per hour.

Per diem respiratory therapy generally pays $40 to $60 per hour, sometimes higher for hard-to-fill nights and holidays. The tradeoff is straightforward: better hourly rate, no benefits, and no guaranteed hours. Travel respiratory therapy contracts commonly land between $1,600 and $2,600 per week in total compensation including stipends, and respiratory season pushes strong contracts past $3,000. Crisis rates in a bad flu or RSV month have gone higher than that.

Treat every figure here as a general range that moves with market, license, specialty, and how badly a facility needs coverage this week.

Why Respiratory Season Drives Contract Rates

Respiratory therapy demand is more seasonal than almost any other clinical role, and that seasonality is what makes contract work lucrative. From roughly November through March, influenza, RSV, and COVID admissions raise ventilator census at the same time across an entire region. Every hospital in a metro area needs more RTs in the same eight-week window, and none of them can hire fast enough.

That creates a predictable pattern. Rates start climbing in October as facilities try to staff ahead. They peak in January and February. They soften in April. An RT who plans contracts around that curve, taking a high-rate winter assignment and a lower-rate summer one near home, can out-earn a staff position by a wide margin without working more hours. Facilities that plan ahead lock coverage in September. Facilities that do not end up paying crisis rates in January.

Specialty Add-Ons That Raise Your Rate

The fastest way to increase a respiratory therapist's pay and contract options is to add a specialty credential or documented specialty experience. Facilities pay a premium for RTs who can walk into a NICU or an ECMO circuit without a two-week orientation, because those are the assignments they struggle hardest to fill.

• NPS (Neonatal/Pediatric Specialty): opens NICU, PICU, and pediatric transport assignments, some of the most consistently short-staffed units in the country

• ACCS (Adult Critical Care Specialty): signals advanced vent management and often moves a travel rate up by $150 to $400 per week

• ECMO experience: documented circuit management is rare enough that it functions as its own rate multiplier at large academic centers

• ACLS, PALS, and NRP: baseline expectations for code and transport roles, and a missing card can delay a contract start

• Bronchoscopy assist, PFT, and sleep study competencies: useful for diversifying into daytime and outpatient work later in a career

The Honest Downsides

Respiratory therapy is a night shift profession for a large share of its workforce, and the code team stress is real. RTs are on every code, every rapid response, and every difficult airway. You will run to a room where someone is dying, and you will do it more often than most clinicians in the building. Some RTs find that focus energizing for twenty years. Others burn out in five.

Staffing ratios add to it. Where nursing has ratio standards in many states, respiratory therapy usually does not, so one RT may cover 20 or more ventilated patients plus floor treatments plus codes. That is the single most common reason experienced RTs move to per diem or travel work: not the money alone, but the ability to leave an assignment that is unsafe instead of enduring it for years. Ask about RT-to-vent ratios and code team structure in every interview, staff or contract.

Frequently Asked Questions

How long does it take to become a respiratory therapist?

Most respiratory therapists enter practice in about two years through a CoARC-accredited associate degree program, then pass the NBRC exams and obtain a state license. A bachelor degree in respiratory care takes four years and opens more leadership, education, and specialty roles. Some working CRTs and associate-level RRTs complete bachelor degrees online while employed.

What is the difference between a CRT and an RRT?

Both come from the same NBRC exam sequence. A Certified Respiratory Therapist passes the Therapist Multiple-Choice exam at the lower cut score, while a Registered Respiratory Therapist passes at the higher cut score and then passes the Clinical Simulation Exam. RRT is the standard requirement for acute care, ICU, and nearly all per diem and travel assignments.

How much do travel respiratory therapists make?

Travel respiratory therapy contracts commonly pay between $1,600 and $2,600 per week in total compensation including housing and meal stipends. During respiratory season, strong contracts exceed $3,000 per week, and crisis assignments during severe flu or RSV surges have paid more. Rates vary by state, specialty credentials, and how urgently the facility needs coverage.

Is respiratory therapy a good field for per diem work?

Yes, because respiratory census swings hard by season and by day, so hospitals need flexible coverage year round. Per diem RTs generally earn $40 to $60 per hour without benefits or guaranteed hours. It works well for experienced RRTs who can orient quickly and want control over their schedule.
