What method is commonly used to deliver high flow oxygen therapy?

High-Flow Nasal Cannula (HFNC) is widely recognized as an effective method for delivering high flow oxygen therapy. This therapy provides a higher concentration of oxygen than traditional low flow devices, such as simple face masks or non-rebreather masks. HFNC systems are designed to deliver heated and humidified oxygen at flow rates that can exceed the patient's inspiratory demands, typically reaching up to 60 liters per minute.

One of the key advantages of HFNC is its ability to provide precise levels of oxygen concentration while also offering a comfortable and well-tolerated interface for patients. This is particularly beneficial for patients with respiratory distress, as it ensures that they receive adequate oxygenation without the discomfort that can sometimes accompany other forms of oxygen delivery. Additionally, by also providing a degree of positive pressure due to the high flow rates, HFNC can help recruit collapsed alveoli and improve overall lung function.

In contrast, other options like simple face masks and non-rebreather masks do not maintain such high flow rates and can be less effective in scenarios requiring significant respiratory support. A Venturi mask delivers varied concentrations of oxygen as well but does not achieve the same flow rates as HFNC, making it less suitable for high flow therapy purposes. Thus, HF
