Introduction We aim to evaluate the association between CT findings and SpO2/FiO2 (SF) in hospitalized patients with SARS-CoV-2 pneumonia. Our secondary purpose was to assess the predictive value of the SF ratio to identify critically ill patients and mortality. Methods A prospectively recorded electronic database for all hospitalized patients with SARS-CoV-2 pneumonia was used. CT findings and SF ratio were evaluated on admission. In the clinical course, they were divided into 2 groups as inpatients and critically ill patients to compare. Results During the study period, 256 patients with suspected SARS-CoV-2 were admitted to the hospital. The final cohort consisted of 87 patients. There is a significant moderate to strong negative correlation between the SF ratio and not-, and poorly-inflated lung ratios in critically ill patients (r = -0.591, p = |
