Beschrijving

The GAP index and staging system is a multidimensional prognostic staging system using commonly measured clinical and physiologic variables to predict mortality in patients with idiopathic pulmonary fibrosis (IPF).

Lung physiology: DLCO (% predicted)
Beschrijving

Patients should be scored in the “Cannot perform” category for DLCO if their symptoms or lung function prohibited performance of the DLCO maneuver. If DLCO is unavailable because it was not ordered or not completed because of nonrespiratory limitations, then the model cannot be applied.
