RT332, a kit designed for optimal performance

We've created a kit to optimize delivery of Optiflow Therapy.

Optimal humidity is as much about condensate control as it is about delivering physiologic levels of humidity.

The MR850 uses temperature sensors to adjust the MicroCell™ circuit while also accounting for the geometry of our OptiflowTM cannula. At the same time MicroCell and Evaqua™ technologies work in concert to further control condensate, every step of the way.

MicroCell technology explained

The RT332 Kit contains a Heated Inspiratory Adult Breathing Circuit made of a non-permeable material with Fisher & Paykel’s unique MicroCell Technology.
The MicroCell wall structure forms an insulation shield between the cool air outside and the water vapor inside, locking in humidity and reducing condensation.1
With it’s unique concave base, together with soft contoured prongs and cheek pads, and a customizable headstrap, the Optiflow+ Nasal Cannula provides patient comfort and stability on the face.
