Oxygen Economics: The Use of Heated High-Flow Nasal Oxygen in Air Medical Transport of the Adult Patient

Abstract

The use of oxygen via a heated high-flow nasal cannula (HHFNC) in transport of the adult patient experiencing hypoxemic respiratory failure is an emerging and successful adjunct. Although early intubation was thought to be the safest intervention early in the coronavirus disease 2019 pandemic, what we have learned over the past year was that it would serve the patient best to avoid intubation. We discuss an individual case study of a coronavirus disease 2019–infected patient who required subsequent interfacility air transport to our quaternary care facility. This patient presented to the receiving air medical team on HHFNC. Before January 2021, the capability of this program to transport these patients on HHFNC was not possible because our current ventilation platforms had to be upgraded to include the high-flow option and because of the relative infancy of the HHFNC platforms available for adult air transport. The previously noted approach to not intubate these patients, or to certainly use caution when making the decision to intubate, was not the common theme until late in 2020. Presented in this case discussion will be pertinent positive and negatives as they relate to transporting the patient on HHFNC to include the all-important issue of oxygen supply and demand. The authors would emphasize that the named products in this case are simply products used by the receiving air medical program and do not in any way support an endorsement of these products over any other platforms used to provide positive patient interventions and outcomes.
