What does FEF25-75 stand for in Medical category?

Our objective was to compare which one between PEFR 20% variability vs FEF 25-75.

The fef25-75 is currently the best method to evaluate the small airways of which it appears that you do have some obstruction taking place.The FEF 25-75 is good in that it tells you that your restriction is in your smaller airways and helps your doctors figure out which medications will get to your smaller airways better.Chapter 7 Illustrative Cases on PFT Table 7.1 lists the normal values for the most important PFTs and their grading of severity.My curve in the volume flow loop, is apparently what they felt indicated minimal small airways disease.

FEF(25-75) at 65% of predicted value had a 90% sensitivity and a 67% specificity for detecting a 20% increase in FEV(1) after albuterol inhalation.The lower limit of normal for the FEF 25-75% can be less than 50% of the mean predicted value, making it important to use the lower limit of normal defined by the 95% confidence limit of the mean predicted value rather than a threshold defined by a fixed percentage of the predicted value.There are no published guidelines regarding normal values for FEF 25-75, therefore we used a value corresponding to one standard deviation from the mean FEF 25-75 for all 744 spirometry results obtained from the initial query.The test requires a simple blood draw and is often a routine part of other blood tests.

According to the University of California San Francisco (UCSF), the normal range for serum ALP.The study authors concluded that FEF 25-75% was well correlated with bronchodilator responsiveness in asthmatic children with normal FEV(1).

As suggested earlier, FEF 50% may be indicative of medium-small airway caliber and may be used as an alternative to FEF 25%-75%.

The purpose of FEF 25-75% is to diagnose obstructive diseases, the FEV1 is borderline, meaning that it finds out whether you have asthma or emphysema.A higher BMI was associated with lower total lung capacity (TLC) (%predicted.

Methacholine challenge (MCC) is an important diagnostic tool for asthma, especially in patients in whom routine pulmonary function testing (PFT) is normal or equivocal.
