High flow Nasal oxygen in Acute Respiratory Failure

High flow nasal oxygen (HFNO) therapy represents a significant advancement in the management of acute respiratory failure, offering a blend of heated and humidified oxygen at high flow rates through nasal cannulae. This innovative approach enhances patient comfort, reduces the need for invasive mechanical ventilation by improving oxygenation and CO2 clearance, and supports the natural airway defenses. HFNO's precise delivery of oxygen improves the efficiency of gas exchange and reduces the work of breathing, making it a preferred choice for patients with acute hypoxemic respiratory failure, particularly those with conditions such as pneumonia or COVID-19.
