The median U.S. salary for Respiratory Therapist roles is $64K, and the employment outlook is much faster than average (2026).
A small community hospital or standalone LTACH will often interview a Respiratory Therapist for immediate versatility: can you cover adult floors, ED, ICU, transport, and a difficult airway without needing layers of backup? Large health systems usually run a more structured process: recruiter screen, manager interview, peer panel, and sometimes a skills scenario involving ABGs, ventilator alarms, or escalation during deterioration. In both settings, credentials get you considered; clinical judgment decides the offer. Hiring teams want proof that you can assess a patient independently, communicate a concise recommendation to a provider, and document what happened. Expect questions about ventilator changes, BiPAP tolerance, secretion management, infection-control discipline, and conflicts with nurses or physicians. The strongest candidates explain their reasoning, not just the task they performed.
How to answer: Use a case where you brought objective data: work of breathing, breath sounds, SpO2 trend, ABG, ventilator graphics, or secretion burden. State exactly how you communicated the concern, what escalation path you used, and what changed for the patient; a weak answer merely says that the team eventually agreed with you.
Why they ask: They are testing whether you can advocate for a deteriorating patient without becoming territorial or bypassing the care team. RTs must turn bedside assessment into a clear, clinically defensible recommendation.
Example answer
“On a night ICU shift, a postoperative patient on 4 liters nasal cannula became increasingly tachypneic, with a respiratory rate of 34 and accessory-muscle use despite an SpO2 of 94%. The nurse felt the saturation was acceptable, but I explained that the patient was tiring and requested an ABG and bedside reassessment with the hospitalist. The ABG showed a pH of 7.29 and PaCO2 of 62, so I recommended BiPAP with close monitoring rather than waiting for further decline. I stayed to coach the patient through the mask, adjusted the interface for leak, and reassessed gases after one hour. His respiratory rate fell to 22, PaCO2 improved to 54, and he avoided ICU transfer and intubation.”
How to answer: Choose a real but safe-to-discuss near miss, not a story where someone else caused everything. Explain the immediate patient assessment, notification and documentation steps, then the specific safeguard you adopted, such as a transport checklist, order-verification routine, or ventilator handoff process.
Why they ask: This assesses ownership in a specialty where an overlooked oxygen order, missed circuit issue, or delayed response can rapidly harm a patient. Managers want candor, immediate correction, transparent reporting, and a change in practice.
Example answer
“Early in my career, I received a floor patient after CT and noticed the oxygen flowmeter was set at 2 liters rather than the 4 liters ordered for transport. The patient was stable at 93%, but I recognized that I had not independently verified the flow setting during the handoff. I immediately assessed the patient, returned the oxygen to the prescribed setting, informed the charge nurse and my supervisor, and documented the near miss according to policy. After that, I began using a verbal transport handoff that includes device, flow or FiO2, battery status, and target saturation. In the following year, I completed more than 80 intrahospital transports without a missed oxygen-setting discrepancy.”
How to answer: Describe how you recognized that repeated PRN treatments were not addressing the underlying issue. Include your assessment findings, collaboration with nursing or the provider, interventions you coordinated, and a measurable endpoint such as reduced distress, avoided escalation, or improved airway clearance.
Why they ask: They want an RT who does more than complete treatments and move on. Critical-care and floor coverage require prioritization, reassessment, and follow-through when a patient is not responding as expected.
Example answer
“During a high-census winter shift, I was called repeatedly for albuterol treatments on a COPD patient whose wheezing kept returning. On reassessment, I found coarse rhonchi, weak cough, and thick secretions; the issue was poor clearance, not simply bronchospasm. I coordinated with the nurse to optimize hydration within the care plan, performed airway clearance therapy, obtained a sputum sample, and called the provider with my findings and recommendation for revised secretion management. I returned twice that shift rather than waiting for another PRN call and documented the response each time. By the next morning, the patient was expectorating effectively, needed no additional rescue treatment, and maintained 92% on 2 liters instead of 4.”
How to answer: Show that you first assessed the patient's immediate stability, then used plain-language teaching tied to visible clinical findings. A strong answer includes how you gained cooperation while respecting scope, involved the nurse or provider when needed, and did not promise outcomes you could not guarantee.
Why they ask: RTs routinely work with frightened families during NIV initiation, intubation discussions, pediatric treatments, and end-of-life respiratory care. The interviewer is assessing whether you can preserve empathy without compromising safety or the treatment plan.
Example answer
“I cared for an elderly patient with acute pulmonary edema who was frightened by BiPAP, and her daughter kept asking us to remove the mask because it looked uncomfortable. I explained that her mother's oxygen level was 84% on a nonrebreather and that BiPAP was helping move fluid-related pressure off her lungs while we treated the cause. I adjusted the mask, used brief coached breaks only when her saturation allowed, and asked the daughter to speak calmly and hold her hand instead of arguing over the equipment. I updated the nurse and physician when the patient initially tried to remove the mask. Within 30 minutes, her SpO2 increased to 94%, respiratory rate dropped from 32 to 24, and she tolerated NIV long enough to avoid immediate intubation.”
How to answer: State your sequence: pH, PaCO2, HCO3, compensation, PaO2 or oxygenation context, then bedside correlation. Use a concrete example and explain what you would reassess after intervention; weak answers recite normal values without identifying the clinical priority.
Why they ask: They are checking whether you can move beyond memorizing acid-base labels and use ABGs alongside the patient's presentation. This is central to decisions involving oxygenation, ventilation, NIV, and ventilator adjustments.
Example answer
“I start with the pH to determine acidemia or alkalemia, then determine whether PaCO2 or bicarbonate is driving it and whether compensation is appropriate. For example, a pH of 7.28, PaCO2 of 68, bicarbonate of 31, and PaO2 of 58 on 3 liters suggests acute-on-chronic hypercapnic respiratory failure with hypoxemia in a likely COPD patient. I would immediately assess mental status, respiratory effort, breath sounds, secretion burden, and prior gases before recommending controlled oxygen and a trial of BiPAP if there are no contraindications. I would avoid reflexively increasing oxygen without a target, because the ventilation problem needs treatment. I would repeat clinical assessment and an ABG within the facility protocol, looking for improved pH, falling PaCO2, and reduced work of breathing.”
How to answer: Discuss predicted body weight-based tidal volume, plateau pressure, driving pressure, PEEP and FiO2 titration, and patient-ventilator synchrony. Tie every adjustment to monitoring: exhaled tidal volume, peak and plateau pressures, compliance, SpO2, ABGs, hemodynamics, and ventilator waveforms.
Why they ask: This probes whether you understand lung-protective ventilation, not just how to change a setting. ICU leaders need RTs who can identify unsafe pressures, evaluate synchrony, and communicate trends during rounds.
Example answer
“For ARDS, I use a lung-protective approach and confirm tidal volume is approximately 4 to 6 mL per kilogram of predicted body weight, not actual weight. I monitor plateau pressure with an inspiratory hold and work to keep it at or below 30 cm H2O, while reviewing driving pressure and compliance trends with the intensivist. If oxygenation remains poor, I support PEEP and FiO2 adjustments using the unit protocol while watching blood pressure and signs of overdistention. After any change, I reassess saturation, exhaled tidal volume, alarms, waveform synchrony, and obtain an ABG when indicated. I also flag early if the patient may need proning, deeper sedation, or neuromuscular blockade because ventilator settings alone are not correcting severe dyssynchrony or hypoxemia.”
How to answer: Name suitable presentations such as COPD exacerbation with hypercapnia or cardiogenic pulmonary edema, plus prerequisites including airway protection, cooperation, and manageable secretions. Then name failure indicators: worsening mental status, persistent hypoxemia, rising PaCO2 with acidosis, hemodynamic instability, vomiting, inability to clear secretions, or escalating distress.
Why they ask: NIV is a high-value RT intervention, but delayed intubation in a failing patient is dangerous. The interviewer wants evidence that you can select, coach, monitor, and abandon NIV appropriately.
Example answer
“I consider NIV strongest for an alert patient with COPD-related hypercapnic respiratory failure or acute cardiogenic pulmonary edema who can protect the airway and cooperate with the mask. Before starting, I assess facial fit, aspiration risk, secretion load, baseline ABG, respiratory rate, mental status, and code status. I set an appropriate interface and initial pressures per protocol, stay at the bedside during acclimation, and address leak or anxiety before labeling the therapy a failure. I expect to see lower work of breathing, a declining respiratory rate, and improved pH or PaCO2 within the reassessment window. If the patient becomes somnolent, cannot clear secretions, remains severely hypoxemic, or has worsening acidosis despite optimized settings, I call for immediate provider evaluation and prepare for intubation rather than extending an unsuccessful trial.”
How to answer: Explain pre-test screening, equipment calibration, patient instruction, acceptable maneuvers, repeatability, bronchodilator testing when ordered, and documentation of factors that affect validity. Mention that poor effort should be identified rather than converted into a misleading restrictive or obstructive conclusion.
Why they ask: This separates candidates who can run spirometry from those who understand quality criteria, contraindications, coaching, and test reproducibility. Outpatient and diagnostic departments depend on reliable studies that physicians can interpret with confidence.
Example answer
“I begin by confirming the order, identifying contraindications such as recent thoracic surgery or unstable cardiac symptoms, and documenting smoking, bronchodilator use, height, weight, and demographics accurately. I verify daily calibration and demonstrate the maneuver: full inspiration, explosive start, sustained exhalation, then a complete inhalation when the test requires it. I coach actively and review flow-volume loops for hesitation, cough, early termination, or variable effort rather than accepting the first three attempts. I obtain acceptable, repeatable efforts according to ATS/ERS-based laboratory criteria and document why a test was limited if the patient cannot meet them. If bronchodilator testing is ordered, I record the pre- and post-bronchodilator values and timing precisely so the interpreting clinician can evaluate response.”
How to answer: Say that you go to the bedside immediately, assess the patient and circuit, call for help as needed, and manually ventilate with a bag-valve device if ventilation is compromised. Use the DOPE framework: displacement, obstruction, pneumothorax, and equipment failure, while checking breath sounds, tube depth, secretions, waveform changes, and hemodynamic status.
Why they ask: They are assessing whether you use a disciplined, safety-first ventilator emergency response rather than randomly changing settings. The expected answer prioritizes patient assessment and rapid differentiation of equipment, airway, and lung causes.
Example answer
“I would go directly to the bedside and assess the patient before focusing on the ventilator screen. If oxygenation or ventilation is compromised, I would disconnect from the ventilator and manually ventilate with 100% oxygen while calling for the nurse and provider. I would check tube depth and cuff, inspect the circuit for kinks or water, pass a suction catheter for mucus plugging, and compare bilateral breath sounds while considering pneumothorax. If bagging is difficult with absent unilateral breath sounds and hypotension, I would treat that as an immediate escalation for possible tension pneumothorax. Once the cause is corrected, I would reconnect, verify settings and waveforms, reassess SpO2 and end-tidal CO2, and document the event and response.”
How to answer: Start by assessing work of breathing, mental status, respiratory rate, lung sounds, ABG or VBG need, secretion burden, and code status. Explain the proposed device in patient-centered terms, troubleshoot comfort barriers, involve the provider early, and clearly state the threshold at which refusal plus deterioration becomes an emergency requiring higher-level discussion.
Why they ask: This tests patient autonomy, de-escalation, and whether you recognize that saturation alone does not rule out impending respiratory failure. The interviewer wants a plan that balances consent with urgent reassessment and escalation.
Example answer
“I would not assume 91% means the patient is safe, because visible fatigue may be the more urgent finding. I would assess respiratory rate, accessory-muscle use, mental status, breath sounds, ability to speak, secretions, and obtain a gas if clinically indicated while notifying the nurse and provider. I would ask what the patient dislikes about the mask, then offer a different interface, explain that NIV may reduce the effort of breathing, and use short coached trials if they agree. If they continue to refuse and have decision-making capacity, I would document the discussion and escalate to the provider for an informed refusal and alternative plan. If mental status worsens or they cannot protect the airway, I would activate urgent escalation because the patient may no longer be able to participate safely in that decision.”
How to answer: Identify the required isolation category based on suspected pathogen and facility policy, appropriate PPE, room requirements, and communication with nursing and infection prevention. Discuss whether a clinically appropriate alternative delivery method exists, but make clear that you do not withhold urgently needed therapy simply for convenience.
Why they ask: They are testing infection-control judgment under operational pressure. RTs frequently perform aerosol-generating procedures, and shortcuts can expose staff and other vulnerable patients.
Example answer
“I would first confirm the isolation order and follow the facility's airborne or droplet precautions, including the correct respirator fit and eye protection when required. For a suspected airborne infection, I would ensure treatment occurs in an airborne infection isolation room if available and minimize unnecessary staff entry. I would review whether an MDI with spacer is clinically appropriate instead of nebulization, because it can reduce aerosol dispersion for some patients. If nebulization is necessary, I would use the approved setup, keep the door and precautions in place, and coordinate timing with the nurse so exposure is limited. I would document the treatment response and report any PPE or room-capacity barrier immediately rather than improvising outside policy.”
How to answer: Prioritize based on airway, ventilation, and immediate instability, then delegate or activate backup. Explain what concise handoff information you give for the patient you leave, and identify reassessment points; a weak answer says only that you would handle whichever call came first.
Why they ask: This measures triage judgment in a profession where several patients can deteriorate simultaneously. Managers need RTs who can identify immediate threats, mobilize resources, and communicate rather than trying to handle both alone.
Example answer
“I would rapidly clarify both patients' current status by radio or phone: oxygen saturation, mental status, airway status, respiratory rate, and whether the ICU patient is already back on full support. A severe asthma arrival with silent chest, altered mentation, or rapidly worsening distress is an immediate airway and ventilation threat, so I would request another RT or charge support for the ICU while I respond to the ED. For the ICU patient, I would tell the bedside nurse to return them to prior safe ventilator settings if they are not already there and report any instability to the intensivist. In the ED, I would assess air movement, peak flow if feasible, oxygenation, fatigue, and readiness for continuous bronchodilator therapy, magnesium, NIV, or intubation preparation. Once stabilized, I would return to the ICU, review why the SBT failed, and document both response timelines.”
Interviewers will also have your resume in front of them — make sure it holds up. See our respiratory therapist resume example with salary data and proven bullet points.
More clinical than most allied-health interviews. Expect at least one scenario involving a deteriorating patient, ABG interpretation, ventilator alarms, BiPAP candidacy, or airway escalation. A manager may also ask how you document and communicate a recommendation to a provider. If you have ICU or ED experience, assume they will test whether you understand why you changed an intervention, not just that you performed it.
Do not answer with the national median of $64,280 as though it is a local offer target. Say: "Based on my RRT credentials, experience with [ICU/NIV/PFT/transport], shift expectations, and the total differential structure, I am targeting a base rate in the [specific local range] range; I understand the broader RT market runs roughly from $47,970 to $85,760." Ask separately about night, weekend, critical-care, charge, transport, and incentive differentials. A new graduate should avoid anchoring at the top of the national range unless the role is in a high-cost market or includes scarce specialty coverage.
Some hospitals use a verbal simulation, while others include a skills check, peer interview, or unit walk-through rather than a formal hands-on test. Be prepared to explain what you do for a high-pressure alarm, accidental extubation, failing spontaneous breathing trial, worsening hypercapnia, and poor BiPAP tolerance. If you have not used their exact ventilator platform, say so directly and explain the transferable principles you use. Never bluff familiarity with a device or protocol.
Ask questions that reveal how respiratory care actually functions: "What RT-driven protocols allow independent titration or escalation?" "How are ventilator weaning, proning, rapid responses, and transports staffed?" and "What data does the department track for VAP prevention, unplanned extubations, NIV failure, or treatment turnaround time?" Also ask how new hires are validated on the specific ventilators, blood-gas analyzers, and transport equipment. Avoid ending with only questions about breaks or generic culture.
Lead with validated competencies, clinical rotation cases, and your decision process instead of trying to imitate years of experience. Discuss a specific patient assessment where you recognized distress, interpreted a gas, participated in airway management, or coached NIV under preceptor supervision, while being precise about your role. Emphasize coachability around unit protocols and your readiness for night, weekend, and broad-coverage realities. A strong new graduate sounds safe, observant, and honest about escalation thresholds.
