High flow oxygen therapy is a form of respiratory support used in the hospital where oxygen, often in conjunction with compressed air and humidification, is delivered to a patient at rates of flow higher than that delivered traditionally in oxygen therapy.
Traditional oxygen therapy is up to 16 L/min and high flow oxygen therapy is up to 60 L/min.1
High flow oxygen therapy is usually delivered using a blender connected to a wall outlet, a humidifier, heated tubing and nasal cannula.
This warm, humidified constant flow improves gas exchange and reduces work of breathing. 3
High flow oxygen therapy is commonly used on patients with acute respiratory failure (ie, hypoxemic respiratory failure) in the hospital system. Patients are usually in ICU or high dependency wards, and require assistance with respiration to stabilise breathing and control blood gases.
Humidified high flow oxygen therapy has been used successfully in COPD, bronchiectasis, end-stage cancer and do-not-intubate patients.3
The AcuCare High Flow Nasal Cannula provides high flow oxygen therapy for adult patients with acute respiratory failure. It is designed to deliver continuous oxygen therapy up to a maximum flow of 60 L/min.
The AcuCare High Flow Nasal Cannula is for single-patient use (maximum seven days) in the hospital/clinical environment. It has been designed to provide superior comfort and ease of use to patients requiring high flow oxygen therapy.
