OH-70C High Flow Nasal Cannula Oxygen Therapy Device(HFNC)21

Heated and humidified high flow nasal cannula (HFNC)


Main uses

Heated and humidified high flow nasal cannula (HFNC) is a type of respiratory support method that delivers a high flow (liters per minute) of medical gas to a patient through an interface (nasal cannulae) intended to create a wash-out of the upper airway.

High-flow therapy is useful in patients that are spontaneously breathing but have an increased work of breathing. Conditions such as general respiratory failure, asthma exacerbation, COPD exacerbation, bronchiolitis, pneumonia, and congestive heart failure are all possible situations where high-flow therapy may be indicated.

Why choose us

Flow rate, up to 70L/min flow rate, efficient to provide the minimum FIOnecessary to maintain a SaO≥92%.

Temperature, adjustable from 31℃ to 37℃, increasement by 1℃ to enhance patient comfort level

Humidification, it can deliver 21% – 100% fi02 at flow rates of up to 70 L/min. Even reach to 37℃, it can still ensure almost 100% relative humidity.
