What Are the Clinical Applications of High Flow Nasal Cannula Oxygen Therapy (HFNC) in ICU?



Some people may have heard that High Flow Nasal Cannula (HFNC) is useful, but they don't know the scope of its clinical application in ICU. As a professional medical device manufacturer, Pigeon Medical will introduce it to you today.



1. In ICU, high flow nasal cannula therapy is suitable for acute hypoxic respiratory failure with spontaneous breathing and no hypercapnia-type I respiratory failure, acute respiratory failure, acute respiratory distress syndrome, cardiac surgery, trachea Patients with heart failure before and after intubation or tracheotomy and extubation.



2. The patient uses a dedicated nasal catheter system to produce continuous positive airway pressure (that is, continuous positive airway pressure for non-invasive ventilation) under the condition of continuous high flow output from the device, which prevents alveolar collapse and increases functional disability, reduces the work of breathing, thereby improving oxygenation.



3. In patients with open airways, it provides an effective airway protection strategy; in patients with non-invasive ventilation, it effectively solves the problem of the airway that cannot tolerate high-flow gas.



4. At present, the contraindication range of HFNC application has not been clarified, but as a partial alternative to non-invasive ventilation treatment measures, HFNC (High Flow Nasal Cannula) has a similar contraindication range. If there is no spontaneous breathing and serious internal environment disturbances, but different from non-invasive ventilation, for patients with acute respiratory failure with hypercapnia (type II respiratory failure), HFNC needs to be carefully selected.



5. Judging from our clinical application, HFNC (High Flow Nasal Cannula) has no reliable effect in severe type II respiratory failure, but it can be partially used in patients with compensated type II respiratory failure or mild hypercapnia. HFNC treatment can partially reduce CO2 and enhance humidification, which is helpful for sputum drainage. However, for patients with COPD, attention should be paid to the setting of inhaled oxygen concentration and avoid high-concentration oxygen therapy.
