Recall from the video the demonstration on how to use a spirometer to measure vital capacity (vc). place the steps to measure vc in the correct order from left to right.

Spirometric measures include the following. 1. Forced expiratory volume in 1 s (FEV1) 2. Forced vital capacity (FVC), the maximum amount of air that can be exhaled when blowing out as fast as possible 3. Vital capacity (VC), the maximum amount of air that can be exhaled when blowing out as fast as possible 4. FEV1/FVC ratio 5. Peak expiratory flow (PEF), the maximal flow that can be exhaled when blowing out at a steady rate 6. Forced expiratory flow, also known as mid-expiratory flow; the rates at 25%, 50% and 75% FVC are given 7. Inspiratory vital capacity (IVC), the maximum amount of air that can be inhaled after a full expiration
