Question

that is oxygen High Flow Nasal cannula? What is its Literflow and FiO2? And what type of patient uses this?

Answer 1

Answers :

High-flow nasal cannula (HFNC) therapy

• 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. All settings are controlled independently allowing for greater confidence in the delivery of supplemental oxygen as well as better outcomes when used.

Fio2 on high flow nasal cannula.

• Heat and humidified high flow nasal cannula or as most call it, Hi Flow Nasal Cannula (HFNC), isn't just a standard nasal cannula cranked up to very high flow rates.
• It actually takes gas and can heat it to 37 ^o C with a 100% relative humidity and can deliver 0.21 – 1.00% fi02 at flow rates of up to 60 liters/min.

What type of patient uses high-flow oxygen therapy

• High-flow oxygen delivery has been clinically utilized in a wide spectrum of patient care arenas. It has been administered to patient populations in critical care units, emergency departments, and end-of-life scenarios, and recently has migrated into the home care environment.
• In a recent study conducted by Peters et al, it was demonstrated that patients who would have been treated via NIV were successfully maintained with HFO
• humidified HFNC oxygen therapy can provide adequate oxygenation for many patients with hypoxemic respiratory failure, and may be an alternative to NIV for patients who decline intubation.
• The majority of patients who were placed on HFO were placed on it for oxygenation end-point. A small number were administered HFO to combat increased work of breathing and to enhance secretion removal.
• Based on the clinical evidence, the utilization of HFO therapy in appropriate patients can improve oxygenation and can decrease the patient’s work of breathing without the need for noninvasive or invasive ventilation.
