SARS CoV-2 is the novel corona virus that caused Corona Virus Disease 2019 (COVID-19). The purpose of the study was to determine the use of arterial blood gas (ABG) analysis at admission to predict the mortality among hospitalized patients with COVID-19 pneumonia requiring non-invasive ventilation (NIV). This study was conducted on 300 patients requiring NIV. Demographic and laboratory data including ABG were collected at admission. The subjects were divided into two groups: Success and Failure based on treatment outcome. PaO2 (partial pressure of oxygen in arterial blood) at presentation showed statistically significant association between the two treatment outcome groups. Patients in success group had higher PaO2 at presentation when compared to the failure group. This association was statistically significant with t value of 7.433 and p value of

Key words: Arterial blood gas analysis, COVID-19 pneumonia, Non-invasive ventilation
