Drea Morgan has just come to work at the Inflation Laboratory, and wants to measure her lung capacity (FVC) with our electronic spirometer. She first calibrates the spirometer with a 3 litre calibration syringe, and then blows several huge breaths through the machine, trying to see just how much air she can hold.
