Restrictive vs Obstructive Lung Disease | Flow Volume Loop Interpretation
Welcome back to our Flow Volume Loop mini-series! In this video, Tonya Piehl, RRT and respiratory care educator, breaks down the key differences between restrictive and obstructive lung patterns using easy-to-follow diagrams and clinical reasoning.
✅ Learn how to:
• Identify restrictive lung disease based on reduced lung volumes and normal expiratory flows
• Recognize obstructive lung disease by the scooped-out loop and decreased expiratory flows
• Interpret PFTs and spirometry results like a pro using NBRC-style clinical thinking
• Understand flow-volume loop terms like TLC, RV, vital capacity, PEFR, FEF25-75
This is perfect for students prepping for the NBRC TMC exam, CSE, or anyone needing help with pulmonary function test interpretation.
