The following recommendations pertain to adult and paediatric 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.
Clinical management of severe acute respiratory infection (SARI) when COVID-19 disease is suspected 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 / 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.

How to avoid nosocomial infections with non-invasive
Filter needs to pay attention to the problem of increased resistance to water overload.
The increased resistance needs to be replaced at any time!
Efficiencies in Therapy
Machine complies with patient breathing. However, if there is no inhalation for a certain period of time, the machine
will give a forced ventilation to ensure the minimum ventilation.
G3 B30VT has a pre-heat feature, to
warm your humidifier water up for
ultimate comfort during cold, dry
Accessories replacement reminder
Accessories replacement reminder and reminder cycle can be set for mask, air
tubing and air filter, so that the consumables can be replaced regularly in time to
ensure a better therapy effect.
