Spirometry Course
The Spirometry course will teach individuals how to conduct quality spirometry including: basic lung anatomy and mechanics, spirometry equipment, spirometry indications and contraindications, spirometry test procedures, criteria for acceptability and repeatability, bronchodilator responsiveness testing, spirometry office procedures, and basic spirometry interpretation.
Canadian and international consensus guidelines for the management of asthma and COPD call for routine use of spirometry for the diagnosis and appropriate management of these diseases. In order to meet the need for more access to quality spirometry, RESPTREC® course launched a Spirometry course in 2009, and in response to an expressed need, the online course in 2021. The goal of this course is to ensure those conducting spirometry continue to have the knowledge, skills, and behaviors needed to conduct quality spirometry in order to improve diagnosis and management of chronic respiratory diseases.

- Basic Lung Anatomy and Mechanics
- Spirometry Equipment
- Spirometry Indications and Contraindications
- Spirometry Test Procedures
- Criteria for Acceptability and Repeatability

- Distinguish between normal, obstructive and restrictive patterns.
- Identify how to select the best reportable value and curves including:
- criteria for choosing the appropriate FEV1; and
- FVC.
- Describe when it is necessary to override the computer.
- Describe appropriate communication with patients regarding spirometry results.
Participants must meet the following entrance criteria:
- be employed in a setting where spirometry is routinely performed and have access to spirometry equipment
- be working with or under the supervision of a physician or nurse practitioner who is able to interpret the spirometry results
- have some knowledge of medical terminology and procedures
- have access to a spirometer and 3L calibration syringe
If there is a question regarding met criteria, acceptance to the program will be made on an individual basis and at the discretion of the RESPTREC® Management committee.
The original spirometry course learning objectives and curriculum outline were established by a national expert committee with representation of key groups: Canadian Thoracic Society (CTS), Canadian Respiratory Health Professionals (CRHP), Family Physicians Airways Group of Canada (FPAGC), the Lung Association and various disciplines, in addition to expertise in: guidelines development, technical skills, teaching, and conducting spirometry.
