High Flow Nasal Cannula

Nasal High-Flow Oxygen Therapy (HFNC)

A Next-Generation Respiratory Support Solution

Nasal high-flow oxygen therapy (HFNC) is an advanced respiratory treatment that delivers precisely controlled oxygen concentration and high-flow gas mixtures through an air-oxygen blender. The gas is fully heated and humidified before being administered via a nasal cannula, offering an effective solution for patients with mild to moderate hypoxemia.

As a non-invasive respiratory support method, HFNC enhances oxygenation by:

Flushing out the nasopharyngeal dead space, improving ventilation efficiency.

Delivering warm, humidified gas to reduce respiratory effort.

Generating low-level positive airway pressure for better alveolar recruitment.

HFNC is easy to use, well-tolerated (even in pediatric patients), and holds significant clinical value across various medical settings.

Key Features & Benefits

✔ Precise Control: Adjustable temperature, humidity, and oxygen levels for optimized therapy.

✔ Enhanced Comfort: Minimal nasal obstruction, improving patient compliance.

✔ Stable Oxygen Delivery: Independent flow and FiO₂ adjustment for consistent treatment.

✔ Seamless Transition: Adaptable support for weaning or changing clinical conditions.

✔ Reduced Work of Breathing (WOB): Smaller interface, no device switching, and improved CO₂ washout.

✔ Airway Protection: Maintains mucosal hydration and clearance for better comfort.

✔ Low-Level PEEP Effect: Mimics CPAP benefits by reducing dead space and providing mild positive pressure.

System Components

Air-Oxygen Blender – Ensures accurate gas mixing.

Heated Humidification Chamber – Delivers body-temperature moisture.

Heated Breathing Circuit – Prevents condensation.

Nasal Cannula – Comfortable patient interface.

(Optional: Medical air compressor for standalone operation.)

Clinical Advantages

Efficient CO₂ Clearance: High-flow gas creates a "fresh gas reservoir" in the pharynx, reducing rebreathing.

Reliable FiO₂: Matches patient’s inspiratory flow, eliminating air entrainment and ensuring consistent oxygen delivery.

Reduced Inspiratory Effort: Lowers respiratory muscle workload with gentle support.

Positive Airway Pressure Effect: Increases mean airway pressure, improving oxygenation without invasive ventilation.
