HFNC may be considered "better" in scenarios where patient comfort and humidification are priorities, or where high flow rates are necessary to support oxygenation. CPAP, however, is often superior in situations where continuous positive pressure is needed to prevent airway collapse, such as in obstructive sleep apnea or specific types of respiratory failure. The choice between HFNC and CPAP should be based on the specific clinical needs of the patient.
