In second wave maximum belonged to bronchial asthma group and in third wave maxmimum patients belonged to COPD group. Maximum oxygen requirement noted in ILD group in second wave and COPD group in third wave. Total cases admitted during 2nd wave period was 4216 death rate was 7.2% in whole group and 12% in respiratory illness group. Total admissions in the 3rd wave were 550,death rate was 4.36 % in the whole group and 27% in respiratory illness group. Maximum mortality seen in ILD group in second wave and COPD group in third wave. Higher oxygen utilization, ICU requirement and death were seen in ILD subgroup.Conclusion:- Around 40% of patients with pre-existing respiratory illness required ICU admission. They had high incidence of oxygen requirement, non-invasive ventilation, and mechanical ventilation. The death rate was higher in patients with underlying respiratory illness.FootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 3138.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
