Efeitos do suporte ventilatório não invasivo por meio da pressão positiva bifásica nas vias aéreas em pacientes com doença pulmonar obstrutiva crônica

Abstract

Objective: To describe the benefits and possible complications of using biphasic positive airway pressure (BiLEVEL) in patients with chronic obstructive pulmonary disease (COPD). Methodology: This is a systematic review carried out in June 2022, through the search for articles searched in the PubMed, Cochrane, Scopus, Web of Science databases and published in the last ten years. Literature reviews, books, policy reports, editorials, letters to the editor, conference papers, abstracts, and duplicate studies were excluded. Results and Discussion: A total of 756 articles were identified, 218 articles were excluded because they were duplicates. Of these, 403 were excluded by reading the title, then 93 articles were excluded by reading the abstracts. After reading the articles completely, 33 studies were excluded and 9 studies were included for this systematic review meeting the proposed criteria. The progressive deterioration of lung function is observed in individuals with COPD and can cause persistent hypoxemia, contributing to increased mortality. In addition, it is common for these individuals to present hypoxemia during exercise, which is caused by the difficulty in increasing the tidal volume and consequently increase the respiratory frequency due to breathing with high lung volumes. Final Considerations: The use of non-invasive ventilatory support through BiLEVEL in patients with COPD results in improvements. However, some patients have intolerance and discomfort with the use of this type of NIV, and the use of other better tolerated therapeutic options that present similar results is valid.
