- The training program includes a pre-learning phase that allows participants to familiarize themselves with foundational concepts before engaging in in-person interactions with the facilitator.
- Following the pre-learning phase, participants will have the opportunity to meet with the facilitator in a physical classroom setting. This direct interaction is crucial for addressing any questions or concerns that may have arisen during the self-study period.
- Additionally, the physical classroom component is designed to facilitate hands-on practical training. This aspect of the program allows participants to apply theoretical knowledge in real-world scenarios, enhancing their understanding and retention of the material. Working under the guidance of an experienced facilitator, learners can practice skills, collaborate with peers, and gain valuable insights that are difficult to achieve through online learning alone.
- Overall, this structured approach—combining pre-learning with direct facilitator contact and practical classroom experiences—ensures a comprehensive and effective learning journey that accommodates various learning styles and maximizes participant engagement.

Flow/volume and volume/time graphs
The flow-volume loop is a plot of inspiratory and expiratory flow (on the Y-axis) against volume (on the X-axis) during the performance of maximally forced inspiratory and expiratory manoeuvres.
The volume/time graph is a plot of volume on the vertical Y axis against time on the horizontal X axis.
These are the pictures of spirometry and useful in assessing the validity (acceptability and repeatability) of each and every blow as well as looking at the size and shape of each graph to assist in interpreting results.

Below the flow/volume and volume / time graphs show the worker’s actual blow (solid green and blue lines) against the lower and upper levels of normal, LLN -1.64 and ULN in the grey dotted lines. The predicted PEFR and FVC (Z score 0) are shown on the flow / volume graph and the predicted FEV1, FEV6 and FVC (Z score 0) on the volume / time graph (blue dots).
Looking at these graphs without even seeing the numerical values, It is clear to see that this worker has smaller volumes and flow rates than what is expected for his or her age, height, sex and race.
