The air oxygen blender is an important part of ECMO's equipment. The AD3000-SPD air-oxygen blender precisely controls oxygen concentration and improves CO2 clearance.

1. ECMO is the English abbreviation of extracorporeal membrane oxygenation, which is a technology that represents the level of critical care in a hospital, or even a region or a country.

2. ECMO is a special form of cardiopulmonary bypass that originates from cardiopulmonary bypass and is developed and extended on top of cardiopulmonary support.

3. On February 5, the National Health Commission released the "Diagnosis and Treatment Plan for Pneumonia Infected by Novel Coronavirus Infection (Trial Fifth Edition)" on its official website, which provides the fourth salvage treatment recommendation for respiratory support in the treatment of severe and critical cases, and recommends pulmonary resonation for patients with severe ARDS. In the case of adequate human resources, prone ventilation should be performed for more than 12 hours per day. Extracorporeal membrane oxygenation (ECMO) should be considered as soon as possible in patients with poor prone ventilation.
