Prediction of Postpneumonectomy Pulmonary Function Using ...A simple, practical method is described for estimating unilateral lung function. Overall lung function is plied by right-left fractional perfusion estimated from a quantitative technetium ferric hydroxide macroaggregate lung scan. The calculated function attributed to the lung to be resected is then subtracted from the overall pulmonary function.

Pulmonary Function Correlates in the Prediction of Long ...More recently, the inverse correlation between lung function and nutrition-that is, that improved nutrition status can positively affect pulmonary decay-was established. In support of that correlation, it has been shown that aggressive nutritional intervention improves, stabilizes, or slows the rate of pulmonary function decline.
Clinical Course and Prediction of Survival in Idiopathic ...Idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic interstitial pneumonias and carries the worst prognosis, with median survival ranging from 2.5 to 3.5 years (1, 2).Although IPF has an overall poor prognosis, the clinical course of individual patients varies from slow progression to acute decompensation and death (3, 4). ...
Reference values for lung function: past, present and ...Jul 01, 2010 · Reliable interpretation of pulmonary function results relies on the availability of appropriate reference data to help distinguish between health and disease and to assess the severity and nature of any functional impairment. The overwhelming number of published reference equations, with at least 15 published for spirometry alone in the past 3 yrs, complicates the selection of an appropriate ...
