Suporte ventilatório não invasiva sobre a tolerância ao exercício em pacientes com doença Pulmonar Obstrutiva Crônica (DPOC): revisão de literatura

Abstract

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is a disease that is not fully reversible and usually progressive, where exercise can be difficult to implement due to extreme shortness of breath, decreased muscle strength and fatigue. The objectives of the Non-Invasive Ventilation (NIV) are decreasing the overhead of ventilatory muscles and improve gas exchange. Arising to the hypothesis that the use of this therapy during exercise in patients with COPD could have positive effects. Objective: To determine whether the use of NIV during exercise has positive results in exercise tolerance in patients with COPD, through literature review. Methods: We conducted literature based on Portuguese, English and Spanish literature from the period 2005 to 2015 in Pubmed, Medline, Lilacs, Sciello and references cited by the articles found. Results: The search yielded 85 articles. It was found that 43 articles not related to the theme, leaving 42 articles. It was observed that 32 did not meet the inclusion criteria of the review, ie not related studies on the effects of NIV for two pressure levels, on exercise tolerance in patients with COPD, leaving, so 10 articles. By reading the full texts of these, we selected 08 articles that met the study objective. Conclusion: The VNI results in significant benefits in parameters of Peripheral Oxygen Saturation (SpO2), dyspnoea, improving distance walked and exercise tolerance, corroborating in improvements in quality of life for these patients.
