The predictive role of markers in COVID-19 patients and it’s co-relationship with spo2/fio2and pao2/fio2 ratio,a retrospective observational study in Tertiary care covid ICU

Although it is a known fact that inflammation is caused by infectious diseases, and growing evidence supports its significant role in the progression of various viral pneumonia, including COVID-19 [7]. Severe inflammatory responses contribute to weak adaptive immune response, thereby resulting in immune response imbalance. Therefore, circulating biomarkers that represent inflammation and immune status are known potential predictors for the prognosis of COVID-19 patients [8]. Peripheral white blood cell (WBC) count, neutrophil (NEU)-to-lymphocyte (LYM) ratio (NLR), derived NLR ratio (d-NLR, neutrophil count divided by the result of WBC count minus neutrophil count), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR),interleukin 6 are indicators of the systemic inflammatory response [9] that are widely investigated as useful predictors for the prognosis of patients with viral pneumonia. By collecting the data from confirmed cases, we will attempt to determine the effect of sex, age, CRP, WBC count, NLR, LMR, PLR, and co morbidities on the prognosis of patients with COVID-19 pneumonia and it’s corelation with lungs oxygenation.
