Clinical Results
The following recommendations pertain to adult and pediatric patients with ARDS who are treated with non-invasive or high-flow
oxygen systems.
High-flow nasal oxygen (HFNO) should be used only in selected patients with hypoxemic respiratory failure.
Non- invasive ventilation (NIV) should be used only in selected patients with hypoxemic respiratory failure.
Patients treated with either HFNO or NIV should be closely monitored for clinical deterioration.

Treatment of severe and critical cases:
a. Treatment principle:
Based on symptomatic treatment, actively prevent complications, treat basic diseases, prevent secondary infections, and provide organ function support in a timely manner
b. Respiratory support:
(a) Oxygen therapy: Severe patients should receive nasal cannula or mask to inhale oxygen and evaluate in time whether respiratory
distress and/or hypoxemia is relieved.
(b) High-flow nasal cannula oxygen therapy or non -invasive mechanical ventilation: When patients have respiratory distress and 1 or hypoxemia cannot be relieved after receiving standard oxygen therapy, high-flow can be considered Nasal catheter oxygen therapy or non-invasive ventilation. If the condition does not improve or worsens within a short time (1 to 2 hours ), tracheal intubation and invasive mechanical ventilation should be performed in time.
