Subdivision of lung volumes - inspiratory vital capacityIVC - inspiratory vital capacity

The volume change of the lung between a maximal expiration to residual volume and a full inspiration to total lung capacity. The inspiratory vital capacity is assessed during an inspiratory maneuver, which is not performed forcefully.

The largest of 3 technically satisfactory maneuvers, which differ by no more than 5% or 150 mL (the larger of the two) from the next largest IVC, should be reported. If the difference is larger, then perform up to 8 measurements; if the repeatability criterion is still not met then report the largest IVC with a note that reproducible measurements could not be obtained.
