Updated Course Description 

To avoid possible cross-contamination due to COVID, this NIOSH-approved Spirometry Course will only be taught virtually, using Zoom, in 2021. Attending a virtual spirometry class requires more student preparation than live courses do since the student's spirometer and calibration syringe are used in the virtual course. In addition to that equipment, students also need a PC or laptop with a webcam and a good internet connection.

The class meets from 8-5 EST on Days 1 and 2 and from 8-12:30 EST on Day 3 - the same timing as used in the live course. Students log in 30 minutes ahead of the class time each day so that any new technical issues can be resolved.

Before the class is held, an individual 90-minute Zoom Spirometry Practice meeting is conducted with each student to make sure that their internet connection is good, to review some basic Zoom tools that are used in the class, and also to teach and have each student demonstrate their ability to perform calibration checks. For these meetings, students must use the computer that they will use for the class and be in the location where they will take the course. Students can take the course at work or at home.

This NIOSH-approved Course is designed for healthcare professionals who conduct spirometric pulmonary function tests and/or interpret test results in industrial and clinical settings. It is one of very few NIOSH-approved courses that are approved for continuing medical education credits for nurses and respiratory therapists.

This comprehensive NIOSH spirometry course is appropriate for those with no spirometry background as well as for experienced spirometry users. Though the course assumes no prior spirometry experience or knowledge of respiratory physiology, experienced spirometry users always increase their understanding of spirometry and its results by participating in the course. The goal of this course is to teach not only what the recommendations and requirements are for conducting tests and interpreting results, but also why the recommendations and requirements were made.

Using lectures, discussion, and practice sessions, the course presents basic pulmonary pathophysiology, instrumentation requirements, performance of the spirometry test (stressing active coaching), recognition of testing errors and spirometer malfunctions, observed use of the spirometer, measurement of the spirogram, and interpretation of results.

OSHA and NIOSH standards, the 2013 guidance on Spirometry Testing in Occupational Health Programs: Best Practices for Healthcare Professionals, the 2019 and 2005 American Thoracic Society (ATS) Spirometry Official Statements, the 2014 and 2017 Offical ATS Spirometry Technical Reports, and the American College of Occupational and Environmental Medicine (ACOEM) Statement on Spirometry in Occupational Health - 2020 are reviewed.

In the classes, Dr. Townsend draws on her extensive experience and in-depth knowledge of various spirometers, acquired through on-going consulting with a variety of clients. As she helps clients solve their spirometry problems and identify optimal spirometer configurations, Dr. Townsend obtains new information to share with her students, enabling them to work more effectively with their own equipment and to optimize their spirometry testing skills.

Over half of the class time is devoted to supervised student practice of the techniques that are presented. Individual attention is ensured by maintaining the student/instructor ratio at 6:1 or better. All lectures are given by Dr. Mary Townsend; all practice session assistants are NIOSH-approved and have extensive spirometry experience.

Class size is restricted to 15 or fewer students, to maximize student-faculty interaction and to keep the atmosphere informal and conducive to learning. Topics and presentation styles are varied to keep students interested and involved. Breaks are frequent to help students concentrate and remain focused.

Practical and written examinations are given on the last half-day of the course, and a certificate is awarded if performance is satisfactory. NIOSH-Approved Course certificates remain active for 5 years. Completion of the course is required to obtain continuing education contact hours.

In June, 2010, NIOSH gave their opinion of Dr. Townsend's teaching during her course audit:
"Mary has a wonderful and unique interaction with students. Her subject knowledge is huge. Her energy level keeps students involved and alert. She can communicate with MD's, PhD's, Nurses, Techs, and Aides equally. I believe she does not send students from her course that cannot perform, teach, and collect high spirometry."
