Listen carefully and ask questions if something is not clear. Doing the test correctly is necessary for accurate and meaningful results. In general, you can expect the following during a spirometr…

- Key spirometry measurements include the following: 1. Forced vital capacity (FVC).This is the largest amount of air that you can forcefully exhale after breathing in as deeply as you can. A lower than normal FVC reading indicates restricted breathing. 2. Forced expiratory volume (FEV).This is how much air you can force from your lungs in one second...
