Acute respiratory failure was the primary reason for ICU admission. However, 12% of patients were admitted following a cardiorespiratory arrest.

Three-quarters of the patients required IMV, with a median duration of 5 (3\u201312) days. One-third underwent NIV as initial ventilatory support, but NIV failed in 23% of them. In-hospital mortality was 8%. The composite primary endpoint was observed in 34% of patients.
