As a Paeds RN I will be using Peak flows more routinely to help adolescents understand their Asthma, and be empowered in helping to control their symptoms at home.

Always enjoy an informative asthma update. So relevant in the community, first aid and health care settings. Was great that the audience ask the same questions I wanted answers to as well. Great presenter, have watched most of John's Respiratory lectures/videos.
