Effect of Pursed Lips Breathing for Oxygen Saturation and Peak Expiratory Flow Rate : Systematic Review

Background: Pursed Lips Breathing is a pulmonary rehabilitation therapy that can be reduce peak expiratory flow rate, mean expiratory flow rate, airway resistance decrease and improve lung elasticity. This systematic review aims to determine the effect of pursed lip breathing on peak expiratory flow rate, oxygen saturation, dynamic hyperinflation. Methods: Information relating to this study was found in several journal databases such as MEDLINE, PubMed, Ebsco, CINAHL, Elsevier Science Direct, which are respiratory journals and a collection of research abstracts identified from 2000 to 2017. Results: Pursed lip breathing is an effective therapy against an increase in PEFR and oxygen saturation. Conclusion: Pursed lip breathing is an easy and inexpensive therapy, which may be applicable in solving gas exchange problems and breathing patterns disorders
