The entire test takes roughly 45 minutes. Lung function tests are first and then time is spent prepping for the exercise test. There is a resting and warm up phase prior to starting the exercise stage. Exercise last 8-12 minutes, of which only 2-3 minutes are at a higher intensity. To get the most accurate results, it is important that you give your best effort for as long as you possibly can. If you do not give a maximum effort, your test may be “indeterminate” and a full cardiovascular assessment may not be captured. The exercise workload will be adjusted on an individual basis to help each person give his or her best effort.
