The Fisher & Paykel Optiflow+ Nasal Cannula is a high-flow nasal interface designed exclusively for use with the myAIRVO 2 Humidified High Flow System. It is the part that delivers warmed, humidified high flow to your nose, so it is not used with a standard oxygen concentrator. The cannula uses a concave base with soft contoured prongs to add comfort at the septum and nares. Soft cheek pads with a larger surface area promote stability and help minimize pressure on the face, and an integrated headstrap clip keeps the tubing managed so it is easier to eat, drink, and talk. It comes in three sizes (Small, Medium, and Large) so you can match the fit to your nose. Each cannula is for single-patient use and is not intended to be sterilized or reused. If you are setting up or maintaining your system, you can pair it with the myAIRVO water chamber and the AirSpiral heated breathing tube.
