Validação do protocolo de utilização de uma interface multifuncional de respiração assistida com equipamento de alto fluxo

Abstract

Introduction: Given the devastating COVID-19 pandemic, a multifunctional assisted breathing interface with three uses, including high-flow, was developed and patented to meet or alleviate the high demand for healthcare equipment. Therefore, a protocol for its use was developed to standardize the practices of this therapy. Objective: To validate a protocol for the use of a multifunctional assisted breathing interface with high-flow equipment. Method: This is an experimental and quantitative study conducted in the laboratory of the Clinical Research Unit of the Teaching and Research Management (GEP) of the Federal University of Ceará (UFC) in Fortaleza, Ceará. The study sample consisted of 10 healthcare professionals with proven training in the field involved and experience in the practice of non-invasive ventilatory support. The operationalization occurred through concordance between the responses obtained using a Likert scale. Results: Regarding the language and llustrations, 80% (n=8) of healthcare professionals rated them as adequate. 50% (n=5) and 60% (n=6) indicated the need for revisions to improve interpretation and organization, respectively. Only the application item was rated adequate by 100% (n=10) of physiotherapists. Regarding the protocol suggestions, 60% (n=6) indicated the need to use distilled water when using the high-flow interface; 100% (n=10) questioned the use of tidal volume (TV) monitoring without the appropriate equipment. Conclusion: The evaluated items are adequately structured, but some specific points, such as initial flow monitoring, need to be revised for adequacy. Overall, using the Likert scale, healthcare professionals (judges) expressed satisfaction with the efficiency and applicability of the proposed protocol.
