Is High-Flow Nasal Cannula More Effective Than Conventional Oxygen Therapy for Preventing Escalation of Respiratory Support in Patients With Acute Respiratory Failure?

      High-flow nasal cannula and conventional oxygen therapy demonstrate similar results in the treatment of acute respiratory failure in regard to rates of respiratory support escalation, intubation, mortality, and ICU transfer, although it may decrease the need for escalation of respiratory support and intubation among patients with acute respiratory failure who are undergoing treatment for greater than or equal to 24 hours.
