High-Flow Nasal Cannula

High-Flow Nasal Cannula (HFNC) is a medical device used to deliver oxygen to patients who have difficulty breathing. Unlike standard oxygen masks, HFNC uses a special cannula (a small tube) that fits snugly in the nostrils. It provides a higher flow of oxygen mixed with air, ensuring a comfortable and effective supply of oxygen. The system can also warm and humidify the air, making it easier for patients to breathe in. HFNC is often used in hospitals for conditions like pneumonia or respiratory distress, helping patients breathe better without invasive procedures.
