The scope of the registry is to collect data on small airways function in healthy children, children with cystic fibrosis (CF) and children with non-CF respiratory disease using the multiple breath washout (MBW) system. These data will be stored along with demographic data, clinical data, and traditional pulmonary function testing (PFT) data. The MBW data will be collected with concurrent with clinically indicated PFT testing.~The purpose of the registry is to 1/ establish a locally collected normal range of small airways function across the paediatric age range and 2/ to collect these measurements in CF and non-CF respiratory disease.~Ultimately, the objective of this registry is to validate MBW technology as a tool that can be utilized in clinical care.
There are many techniques that can allow for the quantification of lung function in children; some are being used clinically and others are under development. Many of these tools are available at BC Children's Hospital. This registry study will act as a central repository for the results of traditional and novel pulmonary function tests done at BC Children's Hospital to allow for future analysis.
