Abstract: Objective: To select, assess and summarize the available evidences on prevention of Noninvasive Ventilation (NIV) related Pressure Injuries (PI). Methods: We searched the Registered Nurses' Association of Ontario (RNAO), National Institute for Health and Clinical Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN), National Guideline Clearinghouse (NGC), Guidelines International Network (GIN), Medlive.cn, British Medical Journal Best Practice (BMJ Best Practice), UpToDate, Cochrane Library, Joanna Briggs Institute Library, PubMed, Embase, CNKI, WanFang Data, European Pressure Ulcer Advisory Panel (EPUAP), Wound Ostomy and Continence Nurses Society (WOCN), European Respiratory Society (ERS), Minnesota Hospital Association to collect literatures including guidelines, systematic reviews and consensus. The JBI evidence appraisal and recommendation system was used to evaluate the quality of studies and the level of evidence. Results: 6 references were retrieved including 2 guidelines, 1 evidence summary, 2 systematic reviews and 1 consensus. A total of 23 items of evidences were summarized with regard to identifying risk factors and locations, choosing adequate interface, assessing skin regularly, pressure distribution, using prophylactic dressings, etc. Conclusion: Healthcare workers are supposed to normalize management over noninvasive ventilation equipments and avoid the occurence of pressure related injuries to ensure the safety of patients according to correspondent evidences summarized as well as taking the specific conditions of hospitals into consideration.
