Abstract

INTRODUCTION: Short-term studies have shown benefit for relief of dyspnoea with pursed lip breathing (PLB) in 40% (0 – 60%) of COPD subjects but no long-term studies have been identified (Phys Ther Rev 2009; 14: 240-46). This study aims to evaluate long-term use of PLB using qualitative methodology in a purposive sample of 13 stable COPD subjects. METHODS: All participants were taught PLB using standardised instructions by the same therapist. Follow-up 6 – 24 months after learning PLB was by semi-structured telephone interview and focus group. Where possible the technique of those who reported current PLB use was observed. Telephone transcripts were analysed using a systematic strategy informed by grounded theory and themes that emerged were further explored at focus group. RESULTS: 11 participants took part in the telephone interview, mean age 64.7 yrs (SD 11.8), mean FEV1 44.27% predicted (SD 0.19), focus group (5) and observed PLB (6). Nine reported on-going use of PLB with 8 reporting definite benefit. All those still using PLB used it when they were short of breath. Four distinct themes emerged: use of PLB in relation to physical activity (8/11), to increase confidence and reduce panic (4/11), as an exercise (3/11), at night (3/11). Observation of current technique showed some variations in use but all demonstrated recognisable PLB. Those that had discontinued PLB had done so because it did not help (2) and they had forgotten or were too busy to continue. No substantial adverse effects were reported. CONCLUSION: This preliminary study suggests that in stable COPD benefit from PLB is maintained long-term and gives insight into avenues for further investigation into long-term usage.
