Professional high-flow respiratory unit, humidifying
Definition
An electrically-powered device designed to deliver high-flow (exceeding peak inspiratory flow) heated and humidified ambient air or air/oxygen to a patient in a peri-anaesthesia environment or experiencing a respiratory disorder [e.g., chronic obstructive pulmonary disease (COPD), bronchiectasis, xerostomia, and mucositis]. The gases are delivered as part of noninvasive ventilation (NIV) to the patient's airway via the nose/mouth or a tracheostoma. It consists of a gas flow generator, a heating element, and humidification chamber. It is intended to be used by a healthcare provider on a spontaneously breathing patient.
