Respiratory Therapist Interview Questions
The questions respiratory therapist candidates actually get asked, what each one is really testing, and how to structure an answer that proves clinical judgment under acute respiratory distress, backed by real certification instead of just describing it.
1. Walk me through how you would set up and adjust a ventilator for a patient who is struggling to breathe.
What they're really testing: Covers checking the order, mode and settings, monitoring blood gases and patient comfort, and escalating promptly to the physician when readings worsen.
How to answer: Describe the settings you would check, what readings you watch afterwards, and when you would call the physician.
2. Your patient's oxygen saturation drops suddenly while on a nasal cannula. What are your first steps?
What they're really testing: Assesses the patient before the equipment, checks tubing and airway, increases support safely, calls for help early, and documents the event clearly.
How to answer: Give your first three actions in order, showing that you look at the patient before the machine, then escalate.
3. How do you prevent cross-infection when moving equipment between patients on an isolation ward?
What they're really testing: Describes protective gear, cleaning and disinfecting routines, single-use items, and speaking up when a colleague skips a step.
How to answer: Name the specific steps you follow, then give one example of correcting a colleague or yourself respectfully.
4. You are covering several units and two patients need you at the same moment. How do you choose?
What they're really testing: Prioritises by clinical risk, delegates or calls for backup, communicates with nurses, and records what was delayed and why.
How to answer: Explain your risk-based ranking, who you ask for help, and how you follow up on the patient you could not reach first.
5. What would you do in your first 30 days in this respiratory therapist role?
What they're really testing: Less about the specific plan, more about whether you understand what the role actually needs on day one versus a generic "I'd get to know the team" answer.
How to answer: Ground it in the must-haves for the role — mention how you'd get oriented on ventilator management and airway assessment specifically, not just "learn the systems." Specificity signals you've actually thought about the job, not just the interview.
6. Why are you leaving your current role / why this respiratory therapist position specifically?
What they're really testing: They're screening for red flags (badmouthing a past employer, vague motivation) and for genuine fit with this specific opening, not just any job in the field.
How to answer: Keep it forward-looking and specific to what this role offers that your current situation doesn't — growth, scope, team, mission. Never criticize a past employer, even if the real reason is a bad manager; frame it around what you're moving toward.
What interviewers quietly mark down
The candidate describes equipment settings from memory without mentioning assessing the patient, double-checking orders or escalating early when a patient deteriorates.
Frequently asked questions
How many interview rounds should I expect for a respiratory therapist role?
Most respiratory therapist hiring processes run two to three rounds: an initial screen, a role-specific or panel interview, and sometimes a final conversation with the hiring manager. Senior or specialized versions of this role may add a skills assessment or case study.
Should I prepare questions to ask the interviewer?
Yes — always have two or three ready, specific to the team or the role rather than generic ones you could ask anywhere. Asking nothing reads as low interest; asking only about pay or perks reads as the wrong priorities this early.
