All operations are risky and can mean life or death to the patient. A wide array of equipment is used to make sure operations go well, one being the oxygen membrane. These put oxygen into the patient's blood and take out carbon dioxide while their lungs are not working. The device makes it possible for many patients to have a long life and enjoy what life has to offer. This is because of the way and manner the device functions. It is very good to use on human beings and this article seeks to let you know more about the history, advantages, and functions.
These membranes imitate breathing during cardiopulmonary bypasses, among other operations. They put oxygen into the blood and remove carbon dioxide, which is essential to life. The gas-giving stage is called extracoporeal membrane oxygenation.
The device has a thin penetrable layer in which blood and gas flows separately. In a circuit, oxygen is dispersed and penetrates the blood. The blood on the other hand, expels the carbon dioxide.
Artificial lungs first appeared in the mid 1880s. This was a rotating disk oxygenator by which blood would be allowed to get oxygen from the air. There was a danger of blood clotting and foaming in this procedure. If that occurs, the blood cannot then be put back into the sick person as they will die.
A few more decades, research continued, with a few successful animal tests. The most successful was the design used in the successful 1953 pulmonary bypass operation. It was a stationary type. A thin film of blood was exposed to oxygen while it passed through steel layers.
From the 1950s to 1980s, disposable bubble oxygenators were commonly used in the majority of hospitals. Those that were not disposable were very hard to keep clean. Many times demand for these devices was so high that the staff had to clean it very quickly and well for the next patient in a very short space of time.
As time progressed, membrane oxygenators grew to be the most often used, particularly in the USA. These can oxygenate the same number of liters of blood as bubble oxygenators. However, they need less volume of blood to work properly, so patients suffer less trauma. They work most like actual lungs.
Originally these devices were made from polyethylene or Teflon, which are not penetrable. So enhancements were made and silicone rubber membranes were used as an alternative, which are very absorbent. This proved to show a major gain in patients' blood quality.
Hollow fiber membranes with finer pores are now commonly used for short cardio pulmonary bypass operations. For operations with a longer duration, the medical team uses membranes without pores. The existence of the pores is significant to the amount of time the blood is exposed to oxygen and it must be regulated to normalize a person's bodily function after the operation.
Research is still ongoing into whether bubble oxygenators are better than membrane oxygenators, particularly in adult patients. They cost about the same due to advances in technology. In the developed world, membrane oxygenators continue to be used for cardiopulmonary bypass operations.
