The effect of pep devices in chronic obstructive pulmonary disease patients: A Systematic Review

In cases of severe COPD exacerbations, PEP may lessen the necessity for mechanical ventilation or the degree of ventilator assistance. This may lessen the negative effects of invasive breathing.positive expiratory pressure (PEP) devices are intended to facilitate sputum clearance and reduce cough, but there is limited evidence for their effectiveness in COPD, The aim of this review is to see the effect of pep device in chronic obstructive pulmonary disease. (COPD). Methods: The databases used in this systemic review are PubMed, Google Scholar, Sci hub and Springer from 2010-2023 have been used under the PRISMA approach (Preferred Reporting Items are followed in the current review. Result: Twelve RCTs met the criteria and objectives out of which seven were included in the study. Moderate methodological quality was scored on the PEDro scale. Better lung function has been observed in the patients using pep devices rather than other breathing techniques but physical exercise leads to pulmonary clearance. Conclusion: In patients with COPD or pre-COPD, daily use of the PEP device is safe and may enhance exercise ability. Due to its effectiveness, safety, and low cost, PEP devices could be utilised as an addition to pulmonary rehabilitation programmes
