High‐Flow Tracheal Oxygen for Weaning Mechanically Ventilated Tracheostomized Critically Ill Patients: A Retrospective Study

BACKGROUND: Patients requiring invasive mechanical ventilation (MV) encounter significant morbidity and mortality in the ICU. High-flow tracheal oxygen (HFTO) is used in tracheostomized patients to facilitate MV weaning. However, its impact on clinical outcomes is unclear. We aimed to assess the efficacy of early versus rescue HFTO in tracheostomized patients for successful MV weaning. METHODS: This retrospective, cohort study, included MV …
