forced vital capacity (FVC)
Tidsramme: 3 days after the spine surgery

The changes in the pulmonary functional tests [forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1)].Pulmonary functional tests were performed at the bedside by using a spirometer while the patients in a seated, comfortable position.
