internal jugular venous po2 and oxygen saturation ( measured in 10 patients ) fall linearly with decreasing q below 1.8 ( r = 0.72 and r = 0.88 , p less than 0.0001 , respectively ) , suggesting decreasing flow to perfused areas of the brain and a difference from the rest of the body in its behavior with decreasing q .
