Description

The OPTIFLOW+ DUET ASYMMETRIC NASAL CANNULA by Fisher & Paykel Healthcare Ltd. is an advanced nasal interface designed for high flow therapy, offering non-invasive respiratory support for adult patients. Its innovative asymmetric design features one small prong and one large prong, enhancing the delivery and effectiveness of nasal high flow therapy.

Key Features

• Asymmetric Prong Design: This unique design creates unidirectional flow, optimizing dead space clearance, increasing airway pressure, and improving patient comfort.
• Evaqua™ Technology: Minimizes mobile condensate formation within the circuit, enhancing usability.
• Compatibility: Includes a three-way connector compatible with all Fisher & Paykel circuits, such as Airvo™ and F&P 850 systems.

Comfort and Fit

• Adjustable Head Strap: Provides a secure and soft fit, with a clip that eliminates the need for a lanyard.
• Soft Cheek Pads: Enhance stability and reduce facial pressure.
• Contoured Prongs: Designed for a softer, more comfortable fit.

Usage and Maintenance

• Single-Patient Use: Intended for up to 14 days with no maintenance required, making it suitable for low-resource settings.
• Sterile Water Requirement: For use with humidified high flow systems.

Intended Use

The cannula is designed for nasal high flow (NHF) therapy, providing heated, humidified air and oxygen at flow rates up to 70 L/min. It supports patients with conditions such as COPD and hypoxemic respiratory failure, aiming to reduce the work of breathing, improve ventilatory efficiency, and enhance CO₂ clearance from the upper airway.

Clinical Performance

The asymmetric design targets anatomical dead space, potentially increasing CO₂ clearance, positive end-expiratory pressure (PEEP), and patient comfort. Clinical studies show reduced minute ventilation and inspiratory effort compared to conventional HFNC interfaces.

Compatibility

Compatible with F&P Airvo 2, Airvo 3, and F&P 850 humidified high flow systems. Available in small, medium, and large sizes.

Regulatory Information

• CE-marked, Class IIa Medical Device: Approved for clinical use in Australia, Canada, and the EU.
• Compliance: Meets WHO technical specifications for nasal cannulas and high-flow nasal cannula systems.

Additional Attributes

• Shelf Life: 3 years.
• Global Availability: Commercially available in over 100 countries.
• Intellectual Property Protection: Ensures proprietary design and technology.
