Paper Abstract

We measured the changes in oxygenation of the brain in animals and humans during changes in oxygen delivery (hypotension, shock) or during brain activation (such as finger movement). We found that such changes were measurable. In addition, we found that we were able to detect a change in the oxygenation signal in an animal undergoing heart surgery before the problem was clinically noted, thus suggesting that such methods may allow for earlier intervention in the intensive care setting.
