impact of calculating ROX index in delaying intubation with COVID-19 patients at King Abdullah medical city

Abstract

Background: HFNC is a respiratory mask that covers the nose like an oxygen mask, with the addition of nasal prongs to deliver extra oxygen. At 12 hours, a ROX score above or equal to 4.88 predicts a decreased probability of progressing to mechanical ventilation. Objective: The aim of this study was to evaluate using a high-flow nasal cannula as a potential predictor of delaying intubation. In doing this, the study also sought to verify whether the ROX index accurately predicts HFNC failure for COVID-19 patients treated in the intensive care unit (ICU). Method: Using retrospective observational analysis of prospectively collected data and the study population of patients in the ICUs at KAMC, the study collects and analyzes data using SPSS. Results: P values that are < 0.05 show that the mean differences are statistically significant, and this is seen on days 1-1, day 1-2, day2-1, day 2-2, day 3-1, day 3-2, day 4-2, day 10-1, and day 10-2. This suggests that ROX index can be used in intubation prediction with COVID-19 patients who have respiratory failure type I that received HFNC therapy.
