Oxygen therapy---High-Flow Nasal Cannula Oxygen Therapy
Time : 2021-03-31    Public:AngelBiss Medical Technology Co.,Ltd, A professional OEM producer for respiratory equipments.

In recent years, High-flow nasal cannula oxygen therapy has been more widely used in clinical medicine, and has won unanimous praise from patients.First, we need to understand what is High-flow nasal cannula oxygen therapy.

High-flow nasal cannula oxygen therapy is an oxygen therapy method that directly delivers a certain concentration of air-oxygen mixed concentration gas to the patient without a completely sealed nasal congestion catheter. It can be applied to patients with acute hypoxic respiratory failure, patients after surgery, patients with respiratory failure without tracheal intubation, patients with immunosuppression, patients with cardiac insufficiency, etc. It provides the following functions:

(1) Provides a stable high oxygen concentration and improves blood oxygen quickly and effectively.

(2) Flush the dead space of physiological anatomy, reduce carbon dioxide and inhale again.

(3) Form a certain positive airway pressure to keep the airway open.

(4) Adequate humidification and warming make the airway mucociliary cleansing function in the best condition.

Secondly, what are the advantages of High-flow nasal cannula oxygen therapy?

The first point: It can provide high-concentration oxygen for heating and humidification. The heating and humidifying functions of HFNC can enhance the cleaning ability of mucociliary. Reasonable airway humidification can dilute the secretions of the airway, keep the airway unobstructed and moist, maintain the normal function of the airway, and effectively prevent complications such as lung infection.

The second point: increase functional residual air volume, evaluate the relationship between high-concentration nasal cannula oxygen inhalation, body position and end-expiratory volume through electrical impedance tomography technology. Increase the functional residual volume to increase the overall regional end-expiratory lung impedance.

The third point: bring more comfort to patients.

And, according to research, HFNC can effectively treat acute respiratory failure. It can significantly alleviate the oxygenation state of the body, shorten the treatment time, and the patients have good treatment compliance and high comfort.

Nowadays, HFNC as a new type of oxygen therapy has been widely used in ICU for the treatment of patients with acute respiratory failure. Compared with other oxygen therapy methods, HFNC not only does not affect the patient's oral eating and language communication, but also helps to improve the quality of life.
