Oxycyte: Better than Blood?
AGD: Artificial; something false, misleading or unnatural. Though in the world of modern medicine artificial has taken a vastly different definition. One of hope, second chances and recovery.
According to information from www.cem.msu.edu, a search for artificial blood began in the 19th century with the use of milk. Thankfully, for us now technology has improved and god forbid we need a blood transfusion we won’t be injected with milk!
Claim: That is why I am here to talk to you about Oxycyte. One of the newest up and coming artificial bloods being manufactured and tested by Synthetic Blood International Inc. Oxycyte is one their newest formulas, and is currently in the process of being approved by the FDA.
Preview Structure: First I will discuss what Oxycyte is exactly and how it works in the body. Second, the benefits of using this treatment, and finally discussing the known possible drawbacks due to using Oxycyte.
Point one: Oxycyte is an oxygen carrying emulsion that can carry 50 times more oxygen than hemoglobin, hemoglobin is what your body uses to move oxygen through your body. To put it into perspective, when combined with pure oxygen the amount of Oxycyte in a jar the size of an aspirin bottle can carry as much as the 4liters of blood currently pumping through each one of your bodies! It is a white, completely synthetic substance made of perflurocarbons or PFC’s cited from www.popsci.com. And strangely the chemical makeup very closely resembles the non-stick Teflon in the common frying pan. Hard to imagine that something so close in chemical makeup to a frying pan has potential to save a life.
Oxycyte works by getting more oxygen through damaged blood vessels. Because PFC’s are considerably smaller than red blood cells, or RBC’s, they can squeeze through the damaged vessel where a RBC under normal circumstances would be...
