About FVC Efforts
“FVC” stands for forced vital capacity. The goal of an FVC effort is to measure the volume
and flow of air. Patients inhale fully then exhale forcefully. Sometimes they also inhale
forcefully.
When ready to begin an FVC effort, you coach the patient through these steps.
(If preferred, you may reverse the order of inhaling and exhaling.)
1.
Inhale fully — calmly fill your lungs as much as you can.
2.
Place the flow transducer in your mouth.
3.
Exhale forcefully — as fast as you can, as long as you can.
4.
(Optional) Inhale forcefully — as fast as you can, as long as you can.

You can view and print FVC data in three types of curves, as shown in the following
figures.
