High-Flow Nasal Cannula (HFNC) System with Adjustable Flow Rates and Integrated Humidification

Product Overview: High-Flow Nasal Cannula (HFNC)

High-Flow Nasal Cannula (HFNC) systems are advanced respiratory support devices that deliver heated and humidified oxygen at high flow rates, meeting or exceeding a patient's inspiratory demands. This therapy is beneficial for patients with acute respiratory failure, providing improved oxygenation and comfort compared to conventional oxygen therapies.​

Key Features:

• Adjustable Flow Rates: HFNC systems can deliver oxygen at flow rates up to 60 liters per minute, allowing precise matching to patient needs. ​

• Controlled FiO₂: The fraction of inspired oxygen (FiO₂) can be accurately set between 21% and 100%, ensuring tailored oxygen delivery. ​

• Humidification and Heating: Integrated humidifiers warm and humidify the gas mixture to body temperature (37°C) with 100% relative humidity, enhancing mucociliary function and patient comfort. ​

• Patient Interface: Specialized nasal cannulas designed for high flow rates are used, featuring larger prongs and soft materials to minimize nasal mucosa irritation. ​
