BONHAWA Respiratory Humidifier is intended to provide high flow warmed and humidified respiratory gases for administration to spontaneously breathing patients 20 kg and up, pediatrics to adults in hospitals. It adds heat and moisture to the flow of gases. The flow may be from 2 to 80 L/min depending on the patient interface*. BONHAWA Respiratory Humidifier provides high flow gases with simultaneous oxygen delivery to spontaneously breathing patients without bypassed upper airways in hospitals. * Use of device limited to a flow rate of 70 L/min in the United States.
