Neonatal Nasal High-Flow Oxygen Therapy

Nasal high flow (NHF) is a mode of noninvasive respiratory support that delivers high flows of blended air and oxygen through a nasal interface. NHF is a flow-based therapy designed to be an open system that typically consists of a flow source to blend air and oxygen, a humidifier to heat and humidify the gas mixture, and a circuit and interface to deliver humidified gas to the patient. Suitable sizing of the nasal cannula is important to ensure the open system is maintained. Fisher & Paykel provides the complete system to include the Optiflow non-sealing nasal interface specifically designed for the flow requirements and anatomical features of neonates on NHF therapy.
