ECMO; Heart-lung bypass - infants; Bypass - infants
InformationExtracorporeal membrane oxygenation (ECMO) is a treatment that uses a pump to circulate blood through an artificial lung back into the bloodstream of a very ill baby. This system provides heart-lung bypass support outside of the baby's body.
WHY IS ECMO USED?
ECMO is used in infants who are extremely ill due to breathing or heart problems. The purpose of ECMO is to provide enough oxygen to the baby while allowing time for the lungs and heart to rest or heal.
The most common conditions that may require ECMO are:
- Congenital diaphragmatic hernia (CDH)
- Heart malformations
- Meconium aspiration syndrome (MAS)
- Pneumonia
- Severe air leak problems
- Severe pulmonary hypertension
It may also be used during the recovery period after heart surgery.
HOW IS A BABY PLACED ON ECMO?
Starting ECMO requires a large team of caregivers to stabilize the baby, as well as the careful set-up and priming of the ECMO pump with fluid and blood. Surgery is performed to attach the ECMO pump to the baby through catheters that are placed into large blood vessels in the baby's neck or groin.
WHAT ARE THE RISKS OF ECMO?
Because babies who are considered for ECMO are very ill, they are already at high risk for long-term problems, including death. Once the baby is placed on ECMO, additional risks include:
- Bleeding
- Blood clot formation
- Infection
- Transfusion problems
Rarely, the pump can have mechanical problems (tube breaks, pump stops), which can harm the baby.
However, most babies who need ECMO would probably die if it were not used.

What is extracorporeal membrane oxygenation?
Extracorporeal membrane oxygenation (ECMO) is a special procedure that uses an artificial heart-lung machine to take over the work of the lungs (and sometimes also the heart).
What is refractory hypoxemia?
Refractory hypoxemia is a severe form of low oxygen levels in the blood that does not respond well to standard oxygen therapy. It can be challenging to manage and may require advanced interventions such as mechanical ventilation or extracorporeal membrane oxygenation (ECMO) to improve oxygenation.
How do you remove carbon dioxide from blood?
Normally, the patient would get rid of CO2 by the act of expiration.If this is not the case, it may be necessary to intubate them and control their breathing for them. It may be that their breathing pattern was erratic, shallow or not good enough for gas exchange to take place.
How bad is blood oxygenation of 5?
The average oxygenation level of humans is between 12-14kPa (kilopascals) with levels below 8kPa considered to be critically low. A value of 5 is far below the average and suggests a low haemoglobin/red blood cell count or difficulties in transmitting oxygen across the alveoli/capillary membrane through a disease like emphysema. Interestingly, some of the lowest levels recorded at 3.28kPa were recently measured by a team climbing mount everest.
What is the tylakoid?
it is a membrane. a membrane of a chloroplast.
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
What kind of membrane is cell membrane?
a plasma membrane
Is the outer membrane continuous with the thylakoid membrane?
No, the outer membrane of a chloroplast is not continuous with the thylakoid membrane. The outer membrane surrounds the entire chloroplast, while the thylakoid membrane is an internal membrane system within the chloroplast that contains the pigments and protein complexes necessary for photosynthesis.
Another Name for the plasma membrane of?
the cell membrane
What is plural of membrane?
The plural of membrane is membranes.
The cell membrane also is called the?
The cell membrane is also known as the plasma membrane or the cytoplasmic membrane. It is a biological membrane that separates all cells' interior from the outside, though can be permeated by selection ions and molecules. Its basic function is to protect the cell from its surroundings.
What is inner membrane protein and outer membrane protein How can you get membrane protein from E. coli and how to separate the inner and outer membrane protein?
Inner membrane proteins are embedded in the inner membrane of bacteria, while outer membrane proteins are located in the outer membrane. To obtain membrane proteins from E. coli, you can disrupt the cells through methods like sonication or French press, followed by using differential centrifugation to separate the inner and outer membrane fractions based on their densities. Further purification techniques such as density gradient ultracentrifugation or membrane solubilization can be used to isolate inner and outer membrane proteins specifically.
