Introduction: the SARS-CoV-2 infection has come to change medical health care by pressing for the testing of innovative oxygen administration technics. The high flow nasal cannula therapy (HFNC) stood out in this pandemic, as rather conflicting approaches were taken when caring for COVID-19 patients. Objectives: the purpose of this scoping review is to map available data on the benefits of HFNC in patients with SARS-CoV-2 infection. Material and methods: this scoping review will have Joanna Briggs Institute methodology as guidance. Some criteria of eligibility were taken into consideration to define the population, concept and context, taking into account adults with SARS-CoV-2 (population), high flow nasal cannula (concept) and hospital setting (context). Literature published and not publish in Portuguese, English and Spanish was reviewed, specifically from the year of 2020, and from the following databases: MEDLINE complete, CINAHL complete, PubMed, Cochrane, Nursing & Allied Health Collection and OpenGrey and RCAAP. Two independent reviewers screened the titles and summaries, and latter analysed the complete text of the selected documents, using the relevant information. Results: during the course of this search, 119 articles were found of which 12 were included in this scoping review. In general, all studies presented evidences of the benefits of high flow nasal cannula therapy when caring for patients with SARS-CoV-2 infections, as the reduction of the rate of mechanical ventilation; time of hospital stay; better tolerance of the technic as well as better comfort when compared to other oxygen administration technics. Risk in aerosolization was considered to be reduced provided that specific security measurements are secured. Conclusions: the HFNC in considered to be a secure technic with specific benefits in the care of the SARS-CoV-2 infected patient. We note that nurses have a rather crucial role in the supervision and safety of the HFNC patient.
