Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will be randomised to receive BVS in combination with standard therapy or not throughout a hospital admission for an acute respiratory exacerbation. BVS will be applied when the patient is awake, as an adjunct to chest physiotherapy with a physiotherapist, and for self use for physiotherapy or dyspnoea relief.
