From our results, we conclude that patients with COVID-19 infection followed in the ICU due to pulmonary inflammation (indicated by markers of inflammation and cell damage such as CRP and LDH), consolidation, edema, and ARDS who need oxygen support and IMV continue to suffer from loss of respiratory function and decreased muscle strength, functional capacity, dyspnea, oxygen saturation, balance, quality of life, and fatigue even 6 months after discharge. The gene discussed is CRP; the disease is acute respiratory distress syndrome.
