Features and benefits of the Optiflow+ Nasal High Flow Cannula.


Evaqua Technology reduces formation of mobile condensate 

  • Permeable membrane allows water vapor to freely diffuse through the walls of the tubing

Dual connector fits all F&P circuits 

  • Allows use with both F&P AIRVO™ and F&P 850™ systems

Customizable headstrap provides a secure, soft fit

  • No loose strap ends around the face.
  • Made of softer, tubular material with Stretchwise™ technology.

Headstrap clip removes the need for a lanyard 

  • Works in tandem with the tubing clip to support the weight of the circuit and prevent the cannula from being dislodged
  • No lanyard required
  • Simplifies eating, drinking and communicating in comparison with face masks, by keeping the cannula tubing away from the mouth

Soft cheek pads add  stability and reduce pressure on the face 

  • Larger surface area to reduce pressure points, marks or irritation
  • Improved attachment between cheek pad and headstrap to minimize unintentional disconnection
  • Three colour-coded sizes for instant size recognition setup and troubleshooting

Contoured prongs for a softer, streamlined fit 

  • Anatomical design to improve airflow and sit comfortably in the nares
  • Concave base designed to alleviate pressure on septum
  • Contoured tounobtrusively match the shape of the upper lip

The family of Optiflow interfaces (including Optiflow Junior) are suitable for flows from 2 to 60 L/min.
