Introduction: The severe form of COVID-19 presents with severe inflammatory conditions and difficult-to-resolve respiratory failure, compatible with Acute Respiratory Distress Syndrome - ARDS. This condition requires the use of mechanical ventilation (MV) and is often difficult to wean. Objective: To determine the rate of discontinuation of mechanical ventilation (MV) in patients with COVID-19 treated in intensive care units of three hospitals in southern Brazil. Methods: Medical records of 270 patients with COVID-19 were reviewed to collect information on dates and parameters of MV, as well as health data prior to hospitalization. Length of ICU and MV stay, ICU mortality, use of positive end-expiratory pressure (PEEP) ≥ 10CmH2O, prone positioning, and hemodialysis were calculated. Results: Data from 258 patients were found, the majority of whom were male (56.20%), with a mean age of 62.31 ± 14.51 years. Hospitalizations lasted an average of 13.3 ± 10.12 days and MV was maintained for an average of 11.28 ± 8.91 days. The mortality rate found was 84.11% and 16.28% had successful MV discontinuation. Conclusion: After the institution of invasive ventilatory support, a small proportion of patients with COVID-19 survive without pressure support and the mortality rate is high.
