High Flow Nasal Cannula Use in Patients Outside of the Intensive Care Unit

Pathway Background and Objectives

High flow nasal cannula (HFNC) is commonly used in the Intensive Care Unit (ICU) setting for children with respiratory distress. The HFNC system is designed to heat and humidify gas mixtures so that patients can tolerate high rates of gas flow that meet their respiratory demands. Overall, HFNC, designed to decrease the patient’s work of breathing, decreases the use of CPAP, BiPAP, and mechanical ventilation. This potentially decreases metabolic demand and facilitates safe enteral nutrition earlier. Using specific criteria, HFNC can be initiated on the medical-surgical floors and does not always require ICU level of care. This pathway is designed to ensure an optimal, consistent approach to the medical management of patients with acute respiratory illness on HFNC outside of the ICU setting.

The objectives of this pathway are to:

  • Define the criteria for initiating HFNC on patients who may be appropriately managed outside of the ICU
  • Outline the management for titration and weaning of respiratory support
  • Review the feeding and monitoring guidelines for this group of patients
  • Identify the circumstances under which a Medical Emergency Team (MET) should be activated
