2/3 of the drive to breathe comes from the brain's ability to sense CO2 in the blood ...

Without the gravity that pools the blood to the peripheries it may be important to consider how our vascular pressures are altered to affect the diffusion of CO2 into the brain ...

So, if more blood is goes to the brain, and more CO2 is directed to the brain, will we have more of a tendency to hyperventilate during space travel?

Will prolonged stay in space have an effect on the sensitivity of a certain group of chemoreceptors?

# data[].attributes.body
CO2 sensing controls our rate of breathing (ventilation) and with altered sensing there may be a change in rate of breathing (faster or slower)

CO2 is sensed both centrally and peripherally, if a majority of the blood is "central" how do we get an accurate picture of what's going on peripherally

Given that blood pools to the superior portion of the body while in space (due to lack of gravity), what effect does this have on CO2 sensing?
