Correlation of SaO(2) in patients of COVID-19 with and without COPD

Background: The Covid-19 pandemic has wreaked havoc throughout the world, with 150 million cases to date and over 3 million lives claimed worldwide. Aim: To explored the difference in levels of SaO(2) of COVID-19 positive patients with and without COPD. Study design: Experimental Study. Methodology: From May2020 to 2021 patients admitted at Aziz Bhatti Shaheed hospital were included in this studies. COVID19 was confirmed by RT-PCR.COPD was confirmed by using GOLD standard of diagnostic criteria. SaO(2) was measured by using pulse oximeter and confirmed by blood samples measurement of SaO(2). Statistical analysis: SPSS version 22 was used for data analysis. Paired sample t test was performed to evaluate the hypoxia levels between three pairs among the time distribution of 1st, 3rd, and 6th, day. Results: Levels of SaO(2) were statistically significant between COVID-19 positive patients and COVID-19 positive patients with COPD. We calculated the levels of SaO(2) at day1, 3rd, and 6th day and results were significant to show that COPD might be having some protective effect against hypoxia and that might be due to use of medications or adaptation of pulmonary cells. Conclusion: It was concluded that levels of SaO(2) was significantly reduced in COVID-19 patients without COPD in comparison to patients without COPD.
