Spirometry Demonstration
What will be an ideal response?
If you have a spirometer on hand, use it to identify the volumes for respiration in class. If not, you can use two-liter plastic soda bottles: Crush them, take a deep inspiration, and demonstrate nearly filling two bottles for vital capacity (around 4,800 cc). Expiratory reserve will almost fill up a two-liter bottle (1,200 cc). Use a small soda bottle to relate to tidal volume (400–600 cc). This helps students visualize the actual measures.
