Homework Help: I know that when you hyperventilate, the Pco2 in blood decreases

  1. Oct 23, 2011 #1
    I know that when you hyperventilate, the Pco2 in blood decreases... but is it the venous or arterial PCo2 that's decreasing?
    Can someone please clarify this?
    Thank you!

    I was initially thinking arterial CO2 because after you blow a lot of it out through hyperventilating, less CO2 would be left to go to the body... but I'm not exactly sure :S
