Explain the functioning of PEEP (Positive End-Expiratory Pressure) and its importance in ventilator management.
How to Answer
- 1
Describe what PEEP is in simple terms
- 2
Explain how PEEP maintains end-expiratory lung volume
- 3
Discuss the effects of PEEP on oxygenation and ventilation
- 4
Mention potential complications of inappropriate PEEP levels
- 5
Provide clinical scenarios where PEEP is beneficial
Example Answers
PEEP stands for Positive End-Expiratory Pressure. It is a mode of mechanical ventilation that keeps the alveoli open at the end of expiration, preventing collapse. This improves oxygenation by increasing functional residual capacity and allows for better gas exchange. However, too much PEEP can reduce cardiac output, so it's important to monitor patients closely.
How would you calibrate a ventilator? What steps are involved in ensuring accuracy?
How to Answer
- 1
Understand the manufacturer's guidelines for calibration.
- 2
Use a calibrated gas analyzer to check accuracy of delivered tidal volume.
- 3
Adjust the sensitivity of pressure and flow sensors as needed.
- 4
Conduct a series of tests to confirm the ventilator's performance post-calibration.
- 5
Document all calibration adjustments and results for compliance and safety.
Example Answers
To calibrate a ventilator, I start by reviewing the manufacturer's calibration guidelines. Next, I use a calibrated gas analyzer to measure and confirm the tidal volume accuracy. If there's a discrepancy, I adjust the pressure and flow sensors accordingly. Then, I perform a series of functional tests to ensure the ventilator operates within specifications. Finally, I document the calibration results for future reference.
What safety protocols are necessary when using and maintaining ventilators?
How to Answer
- 1
Always check the ventilator settings before use to ensure they are appropriate for the patient.
- 2
Regularly calibrate and service the ventilator according to manufacturer guidelines.
- 3
Ensure all emergency alarms are functional and tested before patient connection.
- 4
Use personal protective equipment (PPE) when handling ventilators to prevent contamination.
- 5
Educate all staff on proper ventilator use and emergency procedures.
Example Answers
When using a ventilator, I always start by checking the settings to match the patient's needs. Regular calibration is also key, as per the guidelines provided by the manufacturer.
How would you troubleshoot a ventilator that has suddenly stopped working during a procedure?
How to Answer

Example Answers
Crucial metrics include tidal volume, which indicates the amount of air delivered to the lungs with each breath, and should be 6-8 mL/kg for lung protection. Respiratory rate is also vital, typically around 12-16 breaths per minute, to ensure adequate ventilation. Oxygen saturation levels must be monitored to keep above 92%, as this reflects the effectiveness of oxygenation.
How does the ventilatory mode impact oxygen delivery to patients?

- 4
Mention how high FiO2 settings may correlate with different modes.
- 5
Consider the patient's condition and the mode's adaptability for optimal oxygenation.
Example Answers
In Assist-Control mode, the ventilator delivers a set tidal volume which can ensure consistent oxygen delivery, particularly for patients with weak respiratory effort.
How do you evaluate the performance of a ventilator in a clinical setting?
How to Answer
- 1
Assess the ventilator settings and ensure they meet patient needs
- 2
Monitor patient-ventilator interactions for comfort and effectiveness
- 3
Evaluate oxygenation and ventilation parameters with blood gas analysis
- 4
Check for alarms and response times during use
