Validation of lung function prediction equations from patient survival data.

Diagnosing and managing pulmonary disease usually requires judging lung function against predicted values. We explored patient survival data to help identify the best equations for our population. The earliest spirometry, lung volumes and gas transfer data for all Caucasian patients were extracted from our database. Survival status was available for 8,139 patients. Lung function as standardised...

Regression equations for prediction of normal lung function.

We read with interest the study by Nair and colleagues in a recent issue of this Journal 0). The authors have derived regression equations for the prediction of normal lung functions in south Indian children. However, they have not addressed the key issue of the ability of these equations to correctly predict normal values for various parameters. The square of the correlation coefficient (r"), ...

Lung Function Testing Prediction Equations Response: Do They Fit All?

Vanhorebeek and colleagues1 recently addressed the controversies surrounding insulin treatment of hyperglycemia in the ICU. The authors reviewed single-center studies2,3 that demonstrated benefits of tight glucose control, and a multicenter study4 that showed no improvement with insulin use. Failure to achieve glucose targets was proposed to explain the negative multicenter findings.1 This plau...

The Development and Validation of New Equations for Prediction of the Performance of Tangential Cyclones

New equations have been developed to predict the effect of geometrical dimensions of tangential cyclones on their operational performances. To check the validity of the derived equations, an experimental apparatus was set up and some experimental work was performed. It was observed that the experimental results confirm properly the theoretical predictions.
