Measuring Brain Blood Flow and CO2 in Real Time—Why This Changes Concussion Recovery with Dr. Nate Keiser (Part 1) | E57

Dr. Nate Keiser: 00:00 Everything we know about surviving is that like you got to have oxygen. And your body's like, but you know what we're gonna measure? Carbon dioxide. And it's like we're gonna judge if we're living by CO2. And it actually makes sense because it's the it's like the exhaust of the cell. So like the same way a gas car is going to give off exhaust fumes, that is the exhaust fumes of our cellular respiration. So like any cell that is working, it gives off water and it gives off CO2. And so the way your body is measuring if something is active and working is by detecting the CO2 that's coming from it. So it's like looking at exhaust coming out of the exhaust pipe as a way to know how hard that cell is working. And then the reflex to that is like the more CO2 there is, the more we're gonna open up and flush more blood in. But the less CO2 there is, the more we're gonna restrict the flow because we're not using it. And so, in a lot of people that we see, there there are errors in the way that these reflexes are correlating to each other.
