Temperature breathing issues

Good day David,

I've been working on Temperature for the past little while, and I must first say this song has some awesome licks in it!  I've started working my way though chorus 5 and am having a bit of breathing problems.  The chorus opens with a whole note 4 then 4 4+ 3 4 2 ... by the time I get to the 6+ 5 I'm so full of air my lungs feel like they are going to explode.  I'm paying close attention and I don't think my nasal passageway is open (i've even played the lick pinching my nose and I still get too much air).  I've watched the video of you playing this section a number of times but I can't seem to find anywhere where you are venting off some of the excess air (sometimes I really wish your hands were invisible :) ).  Any tips you have of how to breath better in this section would be super helpful.
