Extracorporeal membrane oxygenation In intensive care medicine, extracorporeal membrane oxygenation (ECMO) is an extracorporeal technique of providing both cardiac and respiratory support oxygen to patients whose heart and lungs are so severely diseased or damaged that they can no longer serve their function. An ECMO machine is similar to a heart-lung machine. To initiate ECMO, cannulae are placed in large blood vessels to provide access to the patient's blood. Anticoagulant drugs (usually heparin) are given to prevent blood clotting. The ECMO machine continuously pumps blood from the patient through a "membrane oxygenator" that imitates the gas exchange process of the lungs, i.e. it removes carbon dioxide and adds oxygen. Oxygenated blood is then returned to the patient. There are several forms of ECMO, the two most common of which are veno-arterial (VA) and veno-venous (VV). In both modalities, blood drained from the venous system is oxygenated outside of the body. In VA ECMO, this blood is returned to the arterial system and in VV ECMO the blood is returned to the venous system. In VV ECMO, no cardiac support is provided. VV ECMO can provide sufficient oxygenation for several weeks, allowing diseased lungs to heal while the potential additional injury of aggressive mechanical ventilation is avoided. It may therefore be life-saving for some patients. However, due to the high technical demands, cost, and risk of complications (such as bleeding under anticoagulant medication), ECMO is usually only considered as a last resort therapy. ECMO is most commonly used in NICUs (Neonatal Intensive Care Units), for newborns in pulmonary distress. It is around 75% effective in saving the newborn's life. Newborns can't be placed on ECMO if they are under 4 and a half pounds, thus ruling out the device for most premature newborns. Newborn infants are occasionally placed on ECMO due to the lack of a fully functioning respiratory system or other birth defect, but the survival rates drop to roughly 33%. The time limit for a newborn is usually around 21 day max. Dr. Thomas Krummel, Chairman of General Surgery at Stanford University, held the record for the longest survivor on ECMO at 62 days. This record was in turn broken recently on January 30th, 2008, when a patient at NTU hospital, Taiwan survived a drowning accident after 117 days of ECMO application.[1] "ECMO can have dangerous side effects.

Extracorporeal membrane oxygenation
In intensive care medicine, extracorporeal membrane oxygenation (ECMO) is an extracorporeal technique of providing both cardiac and respiratory support oxygen to patients whose heart and lungs are so severely diseased or damaged that they can no longer serve their function.
An ECMO machine is similar to a heart-lung machine. To initiate ECMO, cannulae are placed in large blood vessels to provide access to the patient's blood. Anticoagulant drugs (usually heparin)
are given to prevent blood clotting. The ECMO machine continuously
pumps blood from the patient through a "membrane oxygenator" that
imitates the gas exchange process of the lungs, i.e. it removes carbon dioxide and adds oxygen. Oxygenated blood is then returned to the patient.
There are several forms of ECMO, the two most common of which are
veno-arterial (VA) and veno-venous (VV). In both modalities, blood
drained from the venous system is oxygenated outside of the body. In VA
ECMO, this blood is returned to the arterial system and in VV ECMO the
blood is returned to the venous system. In VV ECMO, no cardiac support
is provided.
VV ECMO can provide sufficient oxygenation for several weeks,
allowing diseased lungs to heal while the potential additional injury
of aggressive mechanical ventilation
is avoided. It may therefore be life-saving for some patients. However,
due to the high technical demands, cost, and risk of complications
(such as bleeding under anticoagulant medication), ECMO is usually only
considered as a last resort therapy.
ECMO is most commonly used in NICUs
(Neonatal Intensive Care Units), for newborns in pulmonary distress. It
is around 75% effective in saving the newborn's life. Newborns can't be
placed on ECMO if they are under 4 and a half pounds, thus ruling out

bless bless，宝宝一定没问题的
我的产经和产后宝宝离奇经历兼求祝福宝宝已经出生四天了，但是我还没抱过她，更没有喂过她。她也只在我还躺在C-section床上的时候，睁眼看过我。她现在还躺在那里安静的接受治疗。我期盼着她能快点醒过来，快点健康起来。我也渴望大家的祝福！后面我会陆续把我和宝宝的经历，经验和教训都记录下来，给所有的准妈妈...... 好坚强的宝宝和妈妈。祝福！
