Optiflow+ Nasal Cannula


Evaqua™ technology is designed to reduce the formation of mobile condensate

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


The three-way connector fits all F&P circuits

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


A customizable head strap provides a secure, soft fit

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

The head strap clip removes the need for a lanyard.

  • Works in tandem with the tubing clip to support the weight of the circuit, designed to prevent the cannula from being dislodged.
  • Designed to facilitate eating, drinking, and communicating by keeping the cannula tubing away from the mouth.

Soft cheek pads are designed to add stability and reduce pressure on the face

  • Larger surface area designed to reduce pressure points.
  • Improved attachment between check pad and head strap, designed to minimize unintentional disconnection.
  • Three color-coded sizes for instant size recognition.

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 the septum.
  • Contoured to match the shape of the upper lip.
