Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will attend on 2 separate days. On each day they will receive a nebuliser containing 5mg of salbutamol and 500mcg of ipratropium bromide followed after 5 minutes by another nebuliser containg 5mg salbutamol only. On 1 day the nebuliser will be driven by air and on the other day by 8L of oxygen. Patients attend on 2 seperate days so washout period will be at least 24 hours.

Treatment: Drugs
Comparator / control treatment
Each subject will receive the nebulisers driven by air and oxygen as described above. Subjects will act as their own comparators

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be recruited from home oxygen database. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
They will be allocated to the order of either air or oxygen driven nebuliser according to a randomisation sequence obtained by our staistician using a randomisation table created by computer software Subjects and investigators will not however be blinded to the allocation.
Masking / blinding
