Top 10 Questions for Cardiopulmonary Technician Interview

1. Describe the steps involved in performing an arterial blood gas (ABG) analysis.

In performing an arterial blood gas analysis, I would:

• Gather necessary equipment, including a sterile syringe, vacutainer, and heparinized capillary tube.
• Identify the appropriate radial or brachial artery and apply an antiseptic solution to the puncture site.
• Gently insert the syringe or capillary tube into the artery and aspirate the arterial blood sample.
• Transfer the blood sample to a heparinized vacutainer or capillary tube and seal it securely.
• Label the sample with the patient’s name, medical record number, and date and time of collection.
• Transport the sample to the laboratory for analysis.

2. Explain the key physiological parameters measured in an ABG analysis and their clinical significance.

An ABG analysis measures several key physiological parameters, including:

pH

• Reflects the acid-base status of the blood.
• Normal range: 7.35-7.45
• Acidosis: pH below 7.35
• Alkalosis: pH above 7.45

PaCO2 (partial pressure of carbon dioxide)

• Measures the amount of CO2 dissolved in the blood.
• Normal range: 35-45 mmHg
• Hypercapnia: PaCO2 above 45 mmHg
• Hypocapnia: PaCO2 below 35 mmHg

PaO2 (partial pressure of oxygen)

• Measures the amount of oxygen dissolved in the blood.
• Normal range: 80-100 mmHg
• Hypoxia: PaO2 below 80 mmHg

HCO3- (bicarbonate)

• Reflects the body’s acid-base buffering capacity.
• Normal range: 22-28 mmol/L

3. Discuss the different types of ventilators and their applications.

Ventilators are used to provide mechanical ventilation to patients who are unable to breathe adequately on their own. The main types of ventilators include:

• Volume-cycled ventilators: Deliver a preset tidal volume with each breath.
• Pressure-cycled ventilators: Deliver a preset airway pressure and allow the patient to determine the tidal volume.
• Time-cycled ventilators: Deliver a preset number of breaths per minute with a preset inspiratory time.
• Non-invasive ventilators: Used for patients who require ventilatory support but can still breathe spontaneously. Examples include nasal CPAP (continuous positive airway pressure) and BiPAP (bilevel positive airway pressure).
• Invasive ventilators: Used for patients who are unable to breathe spontaneously. Require intubation or tracheostomy.

4. How would you troubleshoot a ventilator that is not delivering adequate ventilation?

If a ventilator is not delivering adequate ventilation, I would troubleshoot the following:

• Check the ventilator settings to ensure they are appropriate for the patient.
• Check the ventilator tubing and connections for leaks or obstructions.
• Ensure that the patient’s airway is clear and unobstructed.
• Check the patient’s chest for adequate rise and fall during ventilation.
• If the ventilator is still not delivering adequate ventilation, I would notify the physician.

5. Describe the principles of non-invasive positive pressure ventilation (NPPV) and its clinical applications.

NPPV is a non-invasive method of providing mechanical ventilation to patients who require ventilatory support but can still breathe spontaneously. It involves delivering positive pressure to the patient’s airway through a nasal mask or mouthpiece.

NPPV is commonly used in the treatment of conditions such as:

• Chronic obstructive pulmonary disease (COPD)
• Neuromuscular disorders
• Obstructive sleep apnea
• Cardiogenic pulmonary edema

6. What are the indications and contraindications for cardiopulmonary resuscitation (CPR)?

Indications for CPR

• Cardiac arrest, confirmed by absence of breathing and pulse.
• Respiratory arrest, confirmed by absence of breathing.
• Unresponsive patient with no signs of circulation.

Contraindications for CPR

• Obvious signs of death, such as rigor mortis or decomposition.
• Terminal illness with a do-not-resuscitate (DNR) order.
• Patient’s specific wishes not to be resuscitated.

7. How would you perform CPR on an adult patient?

To perform CPR on an adult patient, I would:

• Check for responsiveness and breathing.
• Call for emergency medical services (EMS).
• Position the patient on a firm surface and open their airway.
• Give 30 chest compressions at a rate of 100-120 per minute.
• Give 2 rescue breaths, each lasting 1 second.
• Continue CPR until EMS arrives or the patient shows signs of life.

8. What is the role of a cardiopulmonary technician in the management of patients with chronic respiratory conditions?

As a cardiopulmonary technician, I would play a vital role in the management of patients with chronic respiratory conditions, such as asthma and COPD:

• Conduct pulmonary function tests to assess lung function and monitor disease progression.
• Provide patient education on disease management, medication administration, and lifestyle modifications.
• Administer medications, such as bronchodilators and inhaled corticosteroids, as prescribed.
• Monitor patients for signs and symptoms of respiratory distress and escalate care when necessary.
• Collaborate with other healthcare professionals to develop and implement comprehensive treatment plans.

9. How do you stay up-to-date on the latest advancements in cardiopulmonary technology and best practices?

To stay up-to-date on the latest advancements in cardiopulmonary technology and best practices:

• Attend continuing education courses, workshops, and conferences.
• Read medical journals and peer-reviewed research articles.
• Engage in online learning and webinars.
• Participate in professional organizations, such as the American Association for Respiratory Care (AARC), to connect with other professionals and stay informed about new developments.

10. What are your career goals and how do you see yourself contributing to our team?

My career goal is to become a highly skilled and compassionate cardiopulmonary technician. I am eager to contribute to your team by:

• Providing exceptional patient care and support.
• Applying my knowledge and skills to improve patient outcomes.
• Collaborating effectively with other healthcare professionals to ensure a comprehensive approach to patient management.
• Seeking opportunities for professional development and staying abreast of the latest advancements in the field.
• Working diligently to support the team and contribute to the overall success of the department.

Cardiopulmonary Technicians are allied health professionals who provide essential technical support to cardiologists and other healthcare practitioners in the diagnosis and treatment of cardiovascular and pulmonary conditions.
