Implementation of High-Flow Oxygen Therapy in a Surgical High-Dependency Unit: A Cohort Study

The successful implementation of HFOT in SHDUs at SGH highlights its feasibility as an effective alternative to ICU care for selected patients. More than two-thirds of patients who received HFOT were successfully managed without requiring escalation to ICU-level care. This study underscores the importance of structured protocols, staff education, and appropriate resource allocation in ensuring the safe and effective use of HFOT outside of the ICU.
