"pushing in the brain" means creating high pressure in the lungs until you feel it in your head

So like a valsalva maneuver? B/c we already have a word for that.

I think a valsalva maneuver keeps intra-thoracic pressure high by closing up a bit lower the air pathways? At least that is how I do it, it feels like it it bottled up at about the place my larynx site.

That makes more sense to me. An Open glottis definitely is more stimulating to the vagus nerve if nothing else so they are different.
