Conventionally, oxygen is given at 4 to 6 L/min through nasal cannula for supplementation of oxygen. The FiO2 achieved through this can be up to 0.4. Flows more than this can cause dryness to the nasal mucosa without much increase in the FiO2. High-flow nasal cannula (HFNC) uses flow up to 60 L/min. Positive end-expiratory pressure is created in the nasopharynx and it is also conducted to the lower airways. Studies have shown HFNC improves washout of CO2 and decreases respiratory rate. Patient compliance also improves due to the comfort of the cannula compared to the non-invasive ventilation through a mask.

High Flow Nasal Cannula Oxygenation The current pandemic of COVID-19 caused by novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tested the healthcare infrastructure throughout the globe at all possible levels. Early reports suggest about 20% of patients infected with SARS-CoV-2 require hospitalization and 5-8% require admission to intensive care unit (ICU) due to severe disease.Supplementation of oxygen provided by various conventional oxygen therapy (COT) devices (like nasal prongs, face mask, venture mask or non-rebreather mask) may not be sufficient in cases of worsening respiratory failure. One form of escalating respiratory support in such patients is a high flow nasal oxygenation device. High flow nasal cannula oxygenation (HFNC) is a form of non invasive respiratory support. It acts as a bridge between low flow devices and non invasive ventilation and may reduce the need for intubation.

Aeration changes induced by high flow nasal cannula are more homogeneous than those generated by non-invasive ventilation in healthy subjects
