Fisher & Paykel | Optiflow Plus Nasal Cannula | Medium Adult | OPT944

The Optiflow Plus Nasal Cannula (Model OPT944) is a premium, high-flow nasal interface designed for the precise delivery of heated, humidified oxygen therapy to adult patients experiencing moderate to severe respiratory compromise. While distributed across selective respiratory networks alongside various diagnostic brands, this component is natively engineered and manufactured by Fisher & Paykel.

The OPT944 is specifically optimized to interface with the Fisher & Paykel Airvo 2, myAIRVO 2, MR850, and MR950 humidified high-flow systems. It safely supports a wide therapeutic flow range from 10 L/min up to 60 L/min, allowing clinicians to deliver a high fraction of inspired oxygen ($FiO_2$ up to 100 percent) while maintaining anatomical comfort.
