My gelding, Mickey, accidentally kicked me in the gut awhile back and while I didn’t go clear out, I wish I had. Dang, but that HURT.
My baby “went vagal”, as they phrased it in the NICU, twice after neonatal eye exams. Freaked us the hell out. What was interesting to me was how different it was from times she had apnic episodes. With her apnea, she’s sort of slowly fade out, gradually turning from pink to white and then blue. With the vaso-vagal response, she just shut down completely all at once, she turned blue right away and her heart rate plummeted. Much scarier.
