Predictors of outcome of non-invasive ventilation in Patients with acute hypoxemic respiratory failure - a one year hospital based observational study

Abstract

Background and objective: NIV (Noninvasive Ventilation) is one of the most important modality of ventilation which reduces the need for intubation and complications associated with it. However, NIV can not be used in all patients with acute respiratory failure. Hence there is a need to analyse the incidence of failure of NIV and various factors that predict the success and failure of NIV.

Methods: The patients of acute hypoxemic respiratory failure (AHRF) who received NIV were included in study and various parameters such as PaO2/FiO2 ratio, A-a O2 gradient, APACHE II score, SAPS II score, qSOFA score, CURB 65 score were analysed within first 24 hours of admission.
