INTRODUCTION: The use of respiratory devices can cause injuries to the face, causing discomfort, less compliance with ventilatory therapy and irregular, painful and difficult to tolerate support base. The tolerance time is reduced and time of administration of ventilatory or O2 therapy is lengthened.

PURPOSE: To investigate the awareness of nurses about the risk of pressure injuries from respiratory devices, knowledge and application of guidelines about caring and prevention of medical device related pressure injury (MDRPI).

METHOD: In November 2022 we conducted a single centric transversal descriptive observational study, involving 24 nurses from a Pneumology department to a questionnaire consisting of 9 multiple choice questions.

RESULTS: 22 out of 24 nurses replied. 100% are aware that respiratory devices involve MDRPI risks. For 50% of the responders a lesion occurs after 2 hours of stay of the garrison, for the 27% after 1 day, for the 14% after 2 days, for the 4% after 4 days and for the 5% in several days. 95.5% of responders identified the nose bridge as the main location for the development of MDPRI, the others the back of the auricle. 77% of them reassess patient's skin at regular intervals to assess the risk of developing MDRPI, the other 23% don?t perform activity. 45% of nurses said they apply preventive measures for MDRPI risk.

CONCLUSIONS: Results show a lack of knowledge of the guidelines in prevention of MDRPI and consequently an inadequate prevention and monitoring. It is considered necessary to define a Company Protocol and targeted training on the risk of onset of MDRPI, providing periodic moments of training refreshes to improve assistance and ensure proper care for hospitalized people.
