I thought long and hard whether to post this here, but I wanted to share the information with everyone who might have an interest in the issue. The US NAVY has provided a couple of grants to a small company that has been developing a Blood Substitute which reportedly is capable of delivering a much higher level of O2 to the Body than real blood. The company's name is Synthetic Blood Internatinal and their stock symbol is SYBD. I recommend that you read up on the company and the progress that has been made by this company in their attempt to get this product to maket. In my opinion this is a product, if succesful will be capable of helping thousands of people each year(it treats much more than DCS) since O2 therapy is used in many treatments. Anyway since our community has a vested interest in the success of this product you may want to do some research on your own.
