The effectiveness of non-Invasive ventilation in Covid-19 patients

Abstract

Background: Endotracheal intubation is avoided more often with noninvasive ventilation (NIV) in COVID-19 patients with hypoxemia. An endotracheal or tracheostomy tube is not required to use the NIV to deliver mechanical ventilation. When inflating the lungs for oxygenation, positive pressure is provided directly to the airway while negative pressure is applied externally to the abdomen and thorax to draw air into the lungs. Methods: The study was using a quasi-experimental (single-group pre- and post-test design) and sequential sampling approach. Patients hospitalised to the corona complex at LRH-MTI in Peshawar and who tested positive for COVID 19 PCR were selected for the study. Results: There were 34.8 percent of people in the study between the ages of 30 and 45, 38.5 percent between the ages of 46 and 60, and 26.2 percent between the ages of 61 and 75. Co-infections with a positive COVID-19 PCR were found in 47.8% (66) of patients. Overall, 53.6% of patients showed significant improvement after receiving NIV and were subsequently released. For 46.4% of these patients, the NIV did not work, leading to intubation or death. Co-existing diseases were present in the majority of individuals whose NIV attempts were unsuccessful.
