The relationship between CT severity infections and oxygen saturation in patients infected with COVID-19, a cohort study

INTRODUCTION: Thin-section chest computed tomography is an important diagnostic test and utilized to determine the severity of lung involvement in COVID-19 pneumonia. The goal of this study is to examine the relationship between CT severity and the oxygen saturation level of individuals with COVID-19. METHOD: This is a single-center retrospective study of COVID-19 patients that were admitted at a COVID-19 hospital. Patients confirming COVID-19 with PCR testing, patients undergoing lung CT-scan and measures of capillary oxygen saturation using pulse oximetry at the time of admission were all included. RESULT: The total number of the cases were 105. The age was classified into four age groups, with the majority of them falling into the fourth to sixth decade of life (42, 40%). Diabetes was the most common comorbidity disease (29, 27.6%). Pulse oximetry showed hypoxemia in 87 (82.9%) cases. The most common CT finding was ground glass opacities (GGO) (45, 42.9%). The data showed a significant positive correlation between oxygen saturation and CT severity in patients infected with covid-19. CONCLUSION: These findings support the importance of using pulse oximetry to monitor COVID-19 patients in order to evaluate or even estimate their clinical situations.
