Abstract

This study aims to identify the association between oxygen saturation on admission and outcome in COVID 19. This study enrolled 802 adult patients admitted in a tertiary care hospital with confirmed COVID 19 between November 2020 to January 2021. Of the 802 patients, 653 (81.42%) patients were discharged and 149(18.58%) patients died. The patients were categorized into four categories-those with oxygen saturation on admission 90-100%, 80-89%, 70-79% and less than 70% and the respective mortality rates were 6.25%,8.5%,39.66% and 83.33%. Oxygen saturation at admission and the outcome was compared with age and gender. Statistical analysis was done by Chi-Square test and p value was calculated. This study concludes that saturation less than 80% on admission and age more than 55 years is a predictor of in hospital mortality and is independently associated with the outcome.

Keywords: Oxygen Saturation on admission, outcome, Chi square test.
