In part 2 of the spirometry series, we will review and demonstrate the correct technique used to coach a subject in order to achieve accurate results. We will discuss the key variables needed to calculate an individual’s predicted normal range and the preferred reference set used to calculate this range. Through visual discussion, the course also reviews common testing errors and how an acceptable and repeatable test session is defined. It also helps the learner understand the most common patterns of lung disease (obstruction and restriction) through basic analogous modeling. The learner should be able to perform and assess the quality of a test session by the end of this two-part series. Practice in performing the test on subjects thereafter is the final key in obtaining true competency and quality test results.

Chapters & learning objectives
1. Testing the Subject
Chapter 1 describes pretest instructions and demographic parameters that need to be implemented prior to testing the subject, including the importance of accurately measuring the subject’s height. It then reviews errors that make a maneuver unacceptable by using example test results. Finally, there is a demonstration of performing a test on a subject.
2. Putting It All Together
Chapter 2 reviews the factors that determine a subject’s predicted values and which reference set is recommended by the ATS/ERS technical standard. It also describes the two major categories of lung abnormalities: obstruction and restriction. We then review the various grades awarded to a test session based on the acceptability and repeatability of data.
