About 400 units.
"When ECMO rings, there are ten million pieces of gold." This is the first cognizance many people have of ECMO. According to incomplete statistics, there are currently about 400 ECMO devices in China***.
The essence of ECMO is a modified artificial heart-lung machine, the most central part is the membrane lungs and blood pumps, respectively, play the role of artificial lungs and artificial heart, which can be used to provide prolonged cardiopulmonary support for patients with severe cardiopulmonary failure, and win valuable time for the rescue of critical illnesses.
ECMO is currently the core support for severe cardiopulmonary failure, and is known as the "last straw" for critically ill patients.
Details:
ECMO, also known as Extracorporeal Membrane Oxygenation Therapy, or "Yeke Membrane" for short, is also known as an "artificial heart-lung machine" by many doctors. The principle is to drain venous blood from the body to the outside of the body, through the gas exchange device oxygenation and then use the drive pump to perfuse the blood back into the body, so that the heart and lungs get enough rest, for the support of lung function can effectively improve the hypoxemia, to avoid long-term oxygen inhalation caused by oxygen toxicity as well as mechanical ventilation caused by airway damage.
For cardiac function can increase and maintain cardiac output, improve systemic circulatory perfusion, ensure circulatory stability, so as to win time for the recovery of cardiopulmonary function.
ECMO is currently the core support for severe cardiopulmonary failure, and has been called the "last straw" for critically ill patients, but it is expensive.
