Interesting thought! Maybe the connection would be having an oxygen source cut off for a few seconds? I know I'm kinda sensitive to not having access to oxygen for even a little bit (I'll go under water in a pool, but have to take a few preparatory breaths and come up for air very often!) and hate having a blanket over my head (too stuffy, feels like there's no air)
So maybe having oxygen from the cord abruptly cut off and needing to breathe immediately is a little traumatic, but leaving the cord alone until it stops pulsing allows for a more gentle transition to breathing.
