• The HFNC oxygen therapy is carried out using air \ oxygen blender, active humidifier single heated tube and nasal cannula it is respiratory support. • The HFNC continuous to increase easily set up it may also create positive pharyngeal pressure to reduce work of breathing the device midway classical oxygen delivery system like high concentrations CPAP generators. • It is designed a heated humifided mixture of air and oxygen at a high flow than the inspiratory flow. It adjusts the flow rate and body weight provides a degree of distending pressure. • It also decrease the work of breathing and oxygenation. It utilizes a soft large bore nasal prongs it is similar to used on mechanical ventilator with the HFNC. • It overcomes the leading causes of discomfort seen with conventional oxygen therapy. It is a difficult quality level of PEEP generated by the high flow. It support breathing in people with acute heart failure, acute respiratory distress syndrome. • It avoids rebreathing of co2 gas and therefore decreased anatomize dead space. It promoted a slow and deep breathing. It airway hydrated and it improved mucus clearance. • This improves FRC and reduce work of breathing it flows used are high humidification is necessary to avoid drying of respiratory secretions and for maintaining nasal cilia function. • It is mild positive airway pressure and lung volume recruitment. It will titrate FIO2 and flow to promote comfort and oxygen saturation. It ensures the monitor spo2 saturation and pleth wave form. It ensures maintain an o2 saturation on NRB mask It delivery of optimally humidified and warm gases It decreased body energy expenditure. It is used for intubation and extubation support as well as treatment and prevention of post operative respiratory failure and for oxygenation patients during trails or bronchoscopy.
