The Canadian Thoracic Society (CTS) Respiratory Asthma Guidelines recommends, “Asthma control criteria should be assessed at each visit (level IV). Measurement of pulmonary function, preferably by spirometry, should be done regularly (level III) in adults and children 6 years of age and older.” According to A National Report Card published on COPD in Canada, 76% of Ontario physicians have access to spirometry and only 45% use it as a diagnostic tool.

The importance of Spirometry is quite evident. Thus, the Provider Education Program has developed a range of programs for health care providers on this topic.

Some of the programs include:

The role of spirometry in sorting out undifferentiated chest symptoms by Dr. Anthony D’UrzoAU
Spirometry is a quick and simple test that can be performed to determine lung function.  It may be useful in sorting out undifferentiated chest symptoms, including those related to COPD or asthma.  Prior to ordering spirometry anticipate what to do when the test is normal or abnormal and how to make sense of the spirometric overlap between asthma and COPD.

When to do ‘POST Bronchodilator’ Spirometry by Dr. Itamar TamariIT
The following video clip is a quick look at the importance of post bronchodilator spirometry testing for patients with a normal pre test but a history of Asthma.


Why spirometry is not being done by Dr. Eric Hentschel 
The video is a look at why spirometry should be done and the indicators for the need for spirometry.EH
Dr. Hentschel examines chronic cough and how spirometry can help in the diagnosis of asthma; he also discusses the assessment of chronic dyspnea and spirometry aiding its treatment; he highlights patients with suspected and undiagnosed COPD; he elaborates on patients in Canada who have been over diagnosed with asthma but haven’t had spirometry done; Finally he reiterates the importance of including spirometry in early testing on.

Challenges in interpreting Paediatric Lung Function Tests by Dr. Allan CoatesAC
The challenge lies in the fact that children blow their air out at a much faster rate than adults.
Therefore they have much more of that air out before one second is up. As a result the Spirometry isn’t always the only indicator for early disease. You may have to resort to other indices to get more accurate results.

Flow/volume loop shape – Specifically inspired by Kathleen Milks KM
The following video clip is a quick look at the shape of the flow/volume loop, specifically the inspired portion of the loop. Peak inspiratory flow and the overall shape of the inspired curve are effort dependent. Poor patient effort can mimic the same shape or pattern on the inspired loop as a variable extra thoracic obstruction (large airway obstruction). In both these cases there is a flattening of the inspired loop, which you will note on the video.

Spirometry – Calibrate Today by Meridene Haynes MH
This video demonstrates how to correctly calibrate spirometers and how this assures quality test results. It is important to calibrate your spirometer daily, before use or as recommended by the manufacturer.
