Oxygen delivery through high-flow nasal cannulae increase end-expiratory lung volume and reduce respiratory rate in post-cardiac surgical patients. Epub 2011 Sep 9. High-flow nasal oxygen has been shown to provide effective pre-oxygenation and prolong apnoeic time during intubation attempts in non-pregnant patients.
At high flows of 2 litres per kilogram per minute using appropriate nasal prongs a positive distending pressure may be achieved. These devices blow humidified heated oxygen into the nostrils. Due to the high flow rates much of the anatomic dead space especially in the upper.
All settings are controlled independently allowing for greater confidence in the delivery of supplemental oxygen as well as better outcomes when used. Once the flow rate reaches 35Lmin the woman is no longer receiving high flow of oxygen and may benefit from standard low flow oxygen. High-flow nasal cannula HFNC systems use specialized nasal cannulas that allow oxygen to be delivered at an FIO2 of 21100 with high flow rates of 2060 L min.
HFNC is the medical abbreviation for a high-flow nasal cannula. High Flow nasal prongs are not variable performance. Once prescribed flow rate is reached assess requirement for supplemental oxygen.

A The high-flow nasal cannula circuit consists of a flow meter and oxygenair blender connected to a humidifier. They can deliver up to 60 liters of oxygen per minute. Set FiO2 from 21 to 100.
HFNP may act as a bridge between low flow oxygen therapies and CPAP reducing the need for CPAPintubation. The cannula itself is fit into the nares and stabilized with a head strap. High-flow nasal cannula HFNC therapy is an oxygen supply system capable of delivering up to 100 humidified and heated oxygen at a flow rate of up to 60 liters per minute.
In addition high flow oxygen therapy ensures high FiO2. It takes gas is able to heat it to 37 o C with a 100 relative humidity and can deliver 021 - 100 fraction of inspired oxygen FiO 2 at flow rates of up to 60 liters Lmin. We aimed to compare pre-oxygenation using high-flow nasal oxygen 3070 lmin 1 oxygen flow via nasal prongs with standard 15 lmin 1 oxygen breathing via a tight-fitting facemask.
