High Flow Heated Respiratory Humidifiers

The high flow heated respiratory humidifier is primarily utilized to deliver humidified and heated air-O2 mixed gas directly to the nasal cavity through a nasal congestion catheter without the need for sealing. This flow rate exceeds the patient's peak inspiratory flow rate. The oxygen concentration is both precise and adjustable, enhancing breathing comfort. It constitutes an effective respiratory therapy suitable for invasive or non-invasive patients with spontaneous breathing, but not for life support.

Applicable departments include:

Respiratory medicine, ICU, Emergency room, Neurology, Neurosurgery, Cardiothoracic surgery, Pediatrics (≥3 kg), Rehabilitation ward, Geriatric ward, among others.

Clinical characteristics:

In combination with a nasal congestion catheter, it maintains optimal humidity to ensure the comfortable administration of high-flow mixed oxygen gas, achieving the following therapeutic effects:

Auxiliary oxygen supply

Maintains a stable, high inhaled gas oxygen concentration, improves oxygenation, reduces blood oxygen deficiency, and increases effective alveolar ventilation.

Positive airway pressure

Generates low end-expiratory positive pressure (PEEP), reduces breathing power consumption, improves breathing frequency, promotes alveolar opening, facilitating oxygen diffusion.

Reduction of dead space

Minimizes the dead space in the mouth, nose, and pharynx, enhancing oxygen conversion and improving ventilation efficiency.

Airway humidification

Further reduces the dead space in the mouth, nose, and pharynx, promoting oxygen conversion and enhancing ventilation efficiency.
