Course Content: Recent Changes in Standards and Guidelines ATS and ERS Standards and Guidelines   Definitions & Significance of FVC, FEV1, FEF25-75%, Peak Flow, etc. Should FEF25-75% be used to identify "small airways" disease?   Selection & Limitations of Predicted Normal Values Are the predicted values correct for your patient?   Lower Limits of Normal and Occupational Standards Which lower limits of normal should be used?   Interpretation Schemes & Lung Disease Patterns New interpretation schemes with simple to use flow diagrams will be provided. These newer interpretation schemes do not discriminate by using a "fixed" cutoff for the observed FEV1/FVC ratio.   Examples of Obstructive & Restrictive Patterns and Causes Plenty of examples to help understand this important area.   How to Identify an Improperly Performed Test Review of key spirometry pitfalls, recognition, and solutions.   What is a Significant Change in Lung Function with Time The NIOSH technique of a 10% change rarely works in real life. Examples of new techniques will be presented.   Choosing a Spirometer Features to look for when buying a spirometer.   How to read a Flow - Volume display Learn how to recognize obstructive & restrictive patterns, hesitating starts, coughs, and other causes of poor subject effort that may invalidate test results.
