In Group B, those attending the Manchester clinic will have the option of taking part in a 12 month home environmental and pollution monitoring, and sleep monitoring (both optional arms). A pilot study will test the practicalities of running the same protocol in a paediatric population. This will consist of up to 25 children with CF (5-15 years) attending a paediatric clinic in one of the four core centres. Up to 40 healthy volunteers will be recruited to provide samples on a single oc…
