Högflödesbehandling

Högflödesbehandling, often referred to as high-flow nasal cannula (HFNC) therapy, is a method of respiratory support that delivers a specific mixture of heated and humidified air and oxygen through nasal prongs. This technique provides a higher flow rate than traditional nasal cannulas, typically ranging from 15 to 60 liters per minute. The elevated flow rate has several physiological benefits.

One key advantage of högflödesbehandling is its ability to wash out dead space in the upper airway, meaning more fresh gas reaches the alveoli with each breath. This can improve oxygenation and reduce the work of breathing. The humidification also helps to prevent drying of the respiratory mucosa, which can be particularly beneficial for patients experiencing mucus plugging or airway irritation. Furthermore, the positive pressure generated by the high flow can help to stent open the airways, reducing airway resistance and improving ventilation.

Högflödesbehandling is commonly used in various clinical settings, including emergency departments, intensive care units, and general medical floors. It is indicated for patients with mild to moderate hypoxemia, respiratory distress, or those who have undergone extubation and require additional support. It can also be a useful alternative for patients who are intolerant to other forms of non-invasive ventilation. The therapy is generally well-tolerated, with fewer side effects compared to other ventilation methods.
