Respiratory Therapist (RRT, CRT, RT): interview questions for hiring managers
Healthcare Headhunters recruits healthcare professionals for employers. No upfront fee. You pay only if you hire.
This is what we do all day: recruit healthcare professionals.
Interview respiratory therapists for the decisions they make when a treatment response, ventilator alarm, or blood gas changes the plan mid-shift.
No upfront fee. You pay only if you hire.

What should these interview questions reveal?
An NBRC credential does not show how an RT responds when saturation falls after a ventilator change, an ABG conflicts with the bedside picture, or transport disrupts scheduled treatments. Ask about recent decisions, the patient groups served, communication with nurses and providers, and the limits of the candidate’s authority.
We screen credential status and recent ventilator duties. You complete credentialing and clinical assessment before hiring.
Define the assignment before reviewing candidates. Specify adult critical care, emergency, general-floor, neonatal, pediatric, diagnostic, LTACH, or home respiratory duties. A therapist who mainly weans chronic ventilator patients may need a different interview than one covering emergency intubations.
Listen for an assessment-to-action account rather than a list of devices. A useful answer states what the therapist observed, which data they checked, who they contacted, what order or local protocol guided the response, and what changed afterward. Strong candidates describe when they stopped and escalated rather than claiming to solve every problem alone.
Which questions should you ask, and what should a useful answer include?
Ask: “Tell me about a ventilated patient whose condition changed during your shift. What did you assess first?” Useful evidence includes airway patency, breath sounds, alarms, waveforms, delivered pressures or volumes, oxygen delivery, and a clear notification sequence. Ask: “How do you compare an ABG with the patient in front of you?”
- Listen for pH, PaCO2, bicarbonate, PaO2, specimen timing, oxygen delivery, work of breathing, and mental status. The candidate should explain what would prompt reassessment or escalation.
- Ask: “Describe your part in a recent spontaneous breathing trial, extubation, or weaning decision.” Good evidence includes local screening criteria, coordination with nursing and the provider, post-extubation observation, and documentation of the patient response.
- Ask: “Describe a respiratory emergency involving several disciplines.” Useful answers identify a trigger such as airway displacement, mucus plugging, acute bronchospasm, or arrest. Listen for concise communication, task ownership, equipment preparation, charting, and review of the respiratory plan.
- Ask: “Which age groups have you treated independently during the past year?” For pediatric work, ask about age-appropriate equipment and airway experience. Confirm site-required certificates: ACLS, NRP for neonatal work, or PALS for pediatric work. These are not universal legal rules.
- Ask: “How do you keep treatments, equipment checks, and charting current when several patients need attention?” A useful answer gives a real shift sequence. Look for handoff review, timed treatments, equipment rounds, communication about delays, and documented response to therapy.
How should you follow up on the actual work?
Hospitals can produce RTs with ICU, emergency, general-floor, diagnostic, neonatal, or pediatric exposure. LTACH candidates may bring ventilator-weaning and chronic respiratory failure work. Ask what they personally handled and how recently. A setting name alone does not establish comparable duties.
Home respiratory providers may offer experience with oxygen equipment, aerosol therapy, CPAP or BiPAP instruction, troubleshooting, and patient teaching. CoARC-accredited RT programs can introduce new graduates. Candidates may move for commute, scheduled hours, a different patient population, or more frequent use of skills they have not recently used.
Which hiring mistakes should you avoid?
Do not accept “ventilator experience” without asking about modes, alarm problems, transport duties, weaning work, and the patient populations involved. Do not treat RRT or CRT status as the full review. Verify NBRC status, the applicable state RT license, expiration dates, and certificates your site checks.
Do not interview only for emergencies. Ask about handoff, treatment documentation, equipment checks, and recognition of gradual respiratory decline.
How do you use the same questions fairly?
Tell us the patient population, unit coverage, ventilator duties, transport work, treatment schedule, and available RT support. We discuss the applicable state RT license, NBRC RRT or CRT status, and ventilator and ABG experience. Compare shortlisted candidates using unit scenarios: a worsening ABG, repeated high-pressure alarm, or unsuccessful weaning attempt.
Define the assignment
We focus screening on the work your hire will perform.
Review clinical evidence
We review site-required ACLS, NRP, or PALS and recent age-group exposure.
Test your shift scenarios
Assess their review of evidence, escalation contacts, documentation, and recognition of authority limits.
How can we assess ventilator judgment without asking for treatment instructions?
Use a past case or a scenario based on your local policies. Ask what information the candidate would review, how they would identify a change, whom they would involve, and how they would reassess after an authorized action. State ventilator coverage, transports, treatment rounds, and whether another RT is available.
Should we accept a CRT candidate when our opening includes ventilator coverage?
Start with your facility policy, applicable state rules, and the duties assigned. RRT status may carry more weight for independent coverage. When your policy permits CRT candidates, examine recent ventilator work, escalation judgment, and available orientation support.
What should we ask an RT coming from an LTACH?
Ask about ventilator weaning, tracheostomy care, secretion management, chronic hypercapnia, and the frequency of acute escalations. Compare that work with your turnover, emergency-response role, transport duties, and unit practices.
When should NRP or PALS affect the screening decision?
Ask whether the assignment includes neonatal or pediatric coverage, transport, or cross-coverage. Confirm which certificate your site expects and whether it must be active before start. ACLS does not demonstrate neonatal or pediatric preparation.
How can we assess a new RT graduate fairly for our unit?
Ask about clinical rotations, equipment used there, feedback from preceptors, and exposure to ventilator and ABG work. A new graduate may fit when you can provide supervised development rather than assign independent specialty coverage immediately.
How can Healthcare Headhunters help with this hire?
Send us the role, where the person will work and what needs to change with this hire. We will ask about the work, not just the title. Share any license or schedule limits that could rule someone out before we begin the search.
Send us your patient population, shift duties, and credential checks. We will help you structure interviews around the respiratory decisions your next hire will face.
