EFFICACY OF NONINVASIVE VENTILATION IN ACUTE HYPOXEMIC AND HYPERCAPNIC RESPIRATORY FAILURE

Abstract

Background: Noninvasive ventilation (NIV) represents the delivery of positive pressure to the lungs without inserting an endotracheal tube. Noninvasive ventilation has been successfully used in patients with acute respiratory failure. There is a tremendous increase in usage of NIV in clinical settings aiming to reduce complications due to invasive ventilation and to improve resource utilization. It is imperative to watch for outcome of NIV in patients with acute respiratory failure. Noninvasive ventilation (continuous positive airway pressure [CPAP] or noninvasive intermittent positive-pressure ventilation [NIPPV]) appears to be of benefit in the immediate treatment of patients with acute cardiogenic pulmonary edema and may reduce mortality. We conducted a study to determine whether noninvasive ventilation reduces mortality and whether there are important differences in outcome associated with the method of treatment (CPAP or NIPPV). Objectives: To assess the effectiveness of Non Invasive Ventilation in hypoxemic and hypercapnic respiratory failure. Methodology: This descriptive study evaluates the outcomes of Non-Invasive ventilation in Respiratory Failure by using smoking history, ABGs, NIV and patient parameters and to assess the patient outcomes after NIV therapy. Questions were asked from the patients about their age, hospital stay, smoking history, inhaler use and number of exacerbations leading or not leading to hospital admission as per questionnaire. Data was collected by evaluating the patients ABG’s parameters, NIV parameters and other symptoms such as cough, sputum breathlessness and chest tightness Conclusion: According to the study, NIV is effective in improving gas exchange, decreasing intubation, and shortening hospital stays for patients with respiratory failure. The study provides strong evidence for the use of NIV as a first-line intervention in patients with respiratory failure.
