Use of noninvasive ventilation in a hospital of high complexity: factors associated with success or failure

Abstract

Introduction: Noninvasive ventilation (NIV) reduces the need for intubation in patients with acute respiratory failure. However, it is necessary to recognize the factors that predict success or failure of NIV. Objective: Evaluate the determinants of success and/or failure of NIV in intensive care unit. Methods: We evaluated 27 patients, during a period of four months. In the clinical data form, physiological parameters, characteristics of the use of NIV and length of hospital stay were considered. Results: Eighteen selected patients were divided into two groups, successful (G1) and failed (G2) in the use of NIV. Of the patients who used NIV, 61.2% progressed successfully. There were significant differences between groups, the heart rate (p = 0.03), blood pressure (p = 0.03) and Glasgow Coma Scale (p = 0.04). Conclusion: Variables such as heart rate, blood pressure and coma scale Glasgow can determine the success or failure of the use of NIV.
