What is the maximum flow rate for a High-Flow Nasal Cannula (HFNC)?

The maximum flow rate for a High-Flow Nasal Cannula (HFNC) is 60 L/min. This high flow capability allows for the delivery of significant volumes of heated and humidified oxygen to the patient, which can improve oxygenation and comfort compared to conventional nasal cannulas. HFNC systems are designed to flush out the anatomical dead space in the upper airway, providing a higher concentration of oxygen and potentially reducing the work of breathing for patients experiencing respiratory distress. This is particularly beneficial in managing conditions such as pneumonia, exacerbations of chronic obstructive pulmonary disease (COPD), and other respiratory illnesses where higher oxygen demands prevail.

Lower flow rates, as noted in the other options, would not provide the same level of oxygen support or humidification that is essential for certain critically ill patients requiring advanced respiratory support.
