Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.. It is based on a formula which aims to facilitate the calculation of VC when physical measurement testing is not possible. For most people, the maximum lung capacity we reach in our lives is about six liters of air. Doctors often analyze the FVC and FEV1 separately, and then calculate your FEV1/FVC ratio. Results are based on a statistical regression of individuals over age 50. To see Percent Prediced, you must enter observed FVC, FEV1, and FEF25-75% values in the appropriate boxes. For example, a five-year survival rate of 40 percent for a condition would mean that 40 percent of people, or 40 out of 100 people, would be alive after five years.
