Top 10 Questions for Certified Respiratory Therapy Technician (CRTT) Interview

1. Describe the steps involved in performing a pulmonary function test (PFT)?

During a pulmonary function test, I would gather the patient’s medical history and perform a physical exam.

• Explain the test procedure to the patient and obtain their consent.
• Position the patient in a comfortable seated position with their feet flat on the floor.
• Instruct the patient to breathe normally through a mouthpiece connected to the spirometer.
• Monitor the patient’s breathing patterns and record the results.
• Interpret the results of the test and provide a report to the physician.

2. How would you manage a patient with acute respiratory distress syndrome (ARDS)?

Patient Monitoring

• Closely monitor the patient’s vital signs, including heart rate, respiratory rate, and oxygen saturation.
• Assess the patient’s breath sounds and monitor for any changes.
• Monitor the patient’s fluid balance and electrolyte levels.

Respiratory Support

• Administer supplemental oxygen as prescribed by the physician.
• Provide mechanical ventilation if the patient is unable to maintain adequate oxygenation on their own.
• Adjust ventilator settings as needed to meet the patient’s changing needs.

Medications

• Administer medications as prescribed by the physician, such as diuretics, antibiotics, or sedatives.
• Monitor the patient for any adverse effects of medications.

Other

• Provide emotional support to the patient and their family.
• Educate the patient about their condition and treatment plan.
• Collaborate with other members of the healthcare team to provide comprehensive care.

3. What are the different types of mechanical ventilators and how do they work?

There are two main types of mechanical ventilators:

• Positive-pressure ventilators: These ventilators deliver breaths by pushing air into the lungs.
  • Volume-cycled ventilators deliver a set tidal volume.
  • Pressure-cycled ventilators deliver a set airway pressure.
• Negative-pressure ventilators: These ventilators deliver breaths by creating negative pressure around the chest, which causes the lungs to expand.

4. How would you assess a patient’s ability to wean from mechanical ventilation?

• Assess the patient’s respiratory status, including their tidal volume, respiratory rate, and oxygen saturation.
• Assess the patient’s ability to clear secretions.
• Assess the patient’s cognitive status and their ability to follow commands.
• Assess the patient’s nutritional status and their ability to tolerate oral intake.
• Review the patient’s medical history for any conditions that may affect their ability to wean.

5. What are the different types of chest tubes and when are they used?

• Thoracostomy tube: This is the most common type of chest tube. It is used to drain air or fluid from the pleural space.
• Pleural effusion drainage tube: This type of chest tube is used to drain pleural effusion, which is a buildup of fluid in the pleural space.
• Hemothorax drainage tube: This type of chest tube is used to drain blood from the pleural space.
• Pneumomediastinum drainage tube: This type of chest tube is used to drain air from the mediastinum, which is the space between the lungs.

6. How would you troubleshoot a mechanical ventilator?

• Check the power supply and make sure that the ventilator is turned on.
• Check the ventilator tubing for any leaks or obstructions.
• Check the patient’s airway for any secretions or obstructions.
• Check the ventilator settings and make sure that they are appropriate for the patient.
• If the ventilator is still not functioning properly, call for technical assistance.

7. What are the different types of oxygen delivery devices and how do they work?

• Nasal cannula: This is a thin, flexible tube that delivers oxygen through the nostrils.
• Oxygen mask: This is a clear plastic mask that fits over the nose and mouth and delivers oxygen through small holes.
• Venturi mask: This is a type of oxygen mask that delivers a specific concentration of oxygen through small jets.
• Tracheostomy collar: This is a type of oxygen delivery device that is used for patients who have a tracheostomy.
• Mechanical ventilator: This is a machine that delivers oxygen to the lungs through a tube that is inserted into the trachea.

8. What are the different types of respiratory medications and how do they work?

• Bronchodilators: These medications relax the muscles in the airways, making it easier to breathe.
• Anti-inflammatory medications: These medications reduce inflammation in the airways.
• Mucolytics: These medications thin mucus, making it easier to cough up.
• Expectorants: These medications help to expel mucus from the lungs.
• Antibiotics: These medications are used to treat respiratory infections.

9. What are the different types of respiratory therapies and how do they work?

• Chest physiotherapy: This type of therapy uses different techniques to help clear mucus from the lungs.
• Pulmonary rehabilitation: This type of therapy helps patients with chronic respiratory conditions to improve their breathing and overall health.
• Oxygen therapy: This type of therapy delivers oxygen to the lungs through a variety of devices.
• Mechanical ventilation: This type of therapy uses a machine to deliver oxygen to the lungs through a tube that is inserted into the trachea.

10. What are the ethical considerations in respiratory care?

• Patient autonomy: Respecting the patient’s right to make decisions about their own care.
• Beneficence: Acting in the best interests of the patient.
• Non-maleficence: Avoiding causing harm to the patient.
• Justice: Ensuring that all patients have access to quality respiratory care.
• Confidentiality: Protecting the patient’s privacy.

CRTTs play a crucial role in providing respiratory care to patients with compromised respiratory function. Their primary responsibilities include:

1. Patient Assessment and Monitoring

Assess patients’ respiratory status, monitor vital signs, and observe for signs of respiratory distress.

• Obtain patient history, perform physical examinations, and interpret diagnostic tests.
• Monitor patients’ oxygen levels, carbon dioxide levels, and other respiratory parameters.

2. Respiratory Care Interventions

Administer oxygen therapy, using various delivery methods such as nasal cannula, face mask, or mechanical ventilation.

• Provide mechanical ventilation support to critically ill patients, managing ventilators and adjusting settings.
• Perform chest physiotherapy techniques to promote airway clearance and improve breathing.

3. Patient Education and Counseling

Educate patients and their families about respiratory conditions, medications, and self-management techniques.

• Provide guidance on breathing exercises, inhaler use, and oxygen therapy maintenance.
• Counsel patients on smoking cessation, lifestyle modifications, and disease prevention.

4. Equipment Management and Troubleshooting

Maintain and troubleshoot respiratory equipment, including ventilators, oxygen concentrators, and nebulizers.

• Perform routine inspections, cleaning, and repairs to ensure equipment is functioning properly.
• Calibrate and adjust equipment to meet patient-specific needs.
