Dunno if my little story helps or not, but here it is:
When I was born, I had a lump in my throat that kept closing up at night, and I'd stop breathing. I was in and out of the hospital, the docs wanted to do a tracheotomy, but I would have potentially had a lot of complications, at the very least a scar on my neck for the rest of my life.
So my parents decided against the surgery, instead buying a heart monitor, and a bunch of sticky tabs that I wore when I slept for the first two years. The monitor would go off several times a night, alerting my parents that my heart rate had gone too low (in many cases almost stopping)...
Eventually, things got better, my throat grew enough that I could somewhat breath normally (until I had surgery at 13 to reshape my throat, but that's another story). And despite not breathing properly for the first couple years of my life, I don't have any issues from lack of oxygen to the brain, etc.
Not that I know of!
So Zumbo, good luck with everything, babies are so fraglie yet at the same time extremely resilient and adapting. I hope your little girl is happy and healthy for a long time!
