tClinically Indicated
1. After the high-flow gas enters the pharynx through the nose, a fresh gas storage room will be created due to the scouring effect, which can reduce carbon dioxide and then inhale;
2. The high-flow gas is close to the patient's peak inspiratory flow, and it is no longer necessary to inhale some additional air from the air as a supplement, so the patient's actual inhaled oxygen concentration (FiO2) is more reliable;
3. High-flow gas delivery can reduce the patient's inspiratory work and provide low-level respiratory support;
4. High-flow gas can generate low-level positive airway pressure, thereby increasing the average tunnel pressure throughout the breathing cycle.
