P8. Humidification therapy

A study by Rea et al (Rea 2010) found that high flow humidified air delivered via nasal cannulae for up to 2 hours daily reduced annual exacerbation days and days to first exacerbation but not exacerbation frequency  compared with usual care in a group of 108 patients, with COPD/bronchiectasis. Quality of life and lung function also improved. No sham treatment was given. No cost evaluation data were provided in this study
