Pulmonary Function Testing (PFT) Practice Questions
Main Content Areas
The PFT exam focuses on both theoretical knowledge and practical skills, assessing candidates in key areas of pulmonary function testing. Here’s a breakdown of what you need to know.
Key Topics
The exam includes essential areas of pulmonary function testing, such as:
- Lung Volumes and Capacities: Measuring static and dynamic lung functions
- Spirometry: Interpreting flow-volume loops and forced breathing maneuvers
- Diffusion Capacity: Analyzing gas transfer efficiency
- Gas Exchange: Evaluating blood gas analysis for oxygen and carbon dioxide levels
Exam Structure
While the NBRC doesn’t share exact percentage weights for each section, candidates are expected to have a strong understanding of both theoretical principles and their hands-on application.
Detailed Focus Areas
Here’s a closer look at some of the critical topics covered:
| Content Area | Key Focus Points |
|---|---|
| Diagnostic Testing | Bronchoprovocation testing methods |
| Gas Exchange | Comparing pulse oximetry and capnography; interpreting blood gas results |
| Clinical Application | Managing ARDS, using prone positioning, and recognizing risks of mechanical ventilation |
These topics represent the core of the PFT exam. Supplementary resources like Respiratory Cram can help deepen your preparation.

Required Skills and Knowledge
Technical Concepts
To excel on the PFT exam, you need a solid understanding of key respiratory physiology and mechanics, such as:
- Gas Exchange Principles: Includes ventilation-perfusion relationships, diffusion capacity, and blood gas interpretation.
- Lung Mechanics: Covers compliance, resistance, and elastic recoil concepts.
- Flow Dynamics: Focuses on the differences between laminar and turbulent flow and their clinical implications.
These concepts are the building blocks for applying knowledge effectively during the exam.
Clinical Skills
Practical skills are just as important as theoretical knowledge. Here’s what you need to know for test administration and equipment handling:
| Skill Area | What You Should Know |
|---|---|
| Equipment Operation | Calibration procedures, quality control measures, and infection control protocols. |
| Patient Assessment | Pre-test screening, identifying contraindications, and ensuring proper patient positioning. |
| Test Administration | Coaching patients effectively, spotting suboptimal effort, and troubleshooting issues. |
| Emergency Response | Managing adverse reactions and following safety protocols. |
In addition to these hands-on skills, you’ll need sharp analytical abilities to interpret and apply test results.
Analysis Methods
Strong analytical skills are critical for success. Key areas include:
- Pattern Recognition: Distinguishing normal from abnormal results and identifying obstructive or restrictive patterns.
- Quality Assurance: Ensuring test acceptability and reproducibility for reliable outcomes.
- Clinical Correlation: Connecting PFT results with patient symptoms and medical history.
- Data Integration: Combining findings from multiple tests to create a complete clinical picture.
Mastering these areas will help you navigate the exam’s challenges and apply your knowledge in real-world scenarios.
Study Methods
This section offers practical strategies to help you master both the theoretical and hands-on aspects of exam preparation.
Study Materials
Respiratory Cram [1] is a go-to platform for focused learning on topics like lung mechanics, gas exchange, and flow dynamics. Here’s a breakdown of what they offer:
| Resource Type | Focus Area |
|---|---|
| Study Guides | Lung mechanics, gas exchange, flow dynamics |
| Video Lessons | Equipment use, patient positioning, procedures |
| Practice Questions | Clinical interpretation, quality control, pattern recognition |
| Audio Recordings | Key concept reviews, ideal for mobile learning |
These tools can help you organize your study sessions and target key areas effectively.
Study Schedule Tips
A well-structured study plan can make a huge difference. Here’s a simple breakdown:
- Daily Review: Dedicate 2–3 hours to focused study sessions.
- Weekly Check-ins: Use practice questions to spot gaps in your understanding.
- Monthly Progress Checks: Take full-length practice tests to track overall improvement.
- Final Prep: Concentrate on weaker areas during the last two weeks before the exam.
Breaking your study topics into daily, weekly, and monthly goals ensures you cover technical, clinical, and analytical concepts systematically.
Practice Tests
Practice tests are a powerful way to prepare. They help you get comfortable with the exam format, pinpoint weak spots, and improve your test-taking strategies.
Respiratory Cram’s platform [1] offers PFT exam-style questions, detailed explanations, and performance tracking. For $39 per month, you can access their question banks and simulation scenarios.
During the final month, aim to complete one full-length practice test each week. Spend time reviewing incorrect answers to fully understand the reasoning behind the correct ones.
