What is the best course of action to ambulate a patient using a high flow high humidity nasal cannula?

• A. Safe to ambulate with device
• B. Get permission from medical team
• C. Not portable; alternate device needed
• D. Only safe if detached from oxygen source

Answer: (C)

High flow nasal cannula systems deliver heated, humidified oxygen at very high flow rates and typically rely on a dedicated oxygen source and hardware that aren’t designed for easy mobility. Because the equipment is bulky and the connections can be easily dislodged, moving with this setup can interrupt oxygen delivery and create safety risks. For that reason, the safest approach when ambulation is needed is to use an alternative portable oxygen method that is approved for movement, rather than trying to ambulate with a nonportable HFNC. Detaching the device from the oxygen source would defeat the therapy, and while checking with the medical team is wise, it doesn’t change the practical limitation that HFNC is not inherently portable for ambulation.
