Two groups were formed according to the time of starting the combined therapy: Early HFNC+CPAP (first 24 h - EHC) and Late HFNC+CPAP (after 24 h - LHC). A multivariate analysis was performed to establish the strength of the association with ETI and 30-day mortality.Results: 780 patients were included (502 male, mean age 56.5 ± 12.9 years). Table 1 shows the baseline characteristics. 273 patients were subjected to ETI, 32.9% in the EHC group vs 38.9% in the LHC group (p 0.05). 30-day mortality was 8.2% in the EHC vs 15.5% LHC (p 0.02). Table 2 shows the multivariate analysis.Conclusions: The combination of HFNC+CPAP, especially in the first 24 hours after IRCU admission, is a useful tool in the management of SARS-CoV-2 pneumonia.View this table:View this table:FootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 1644.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
