Hypoxia and Medicine

Hi guys, does anyone know what the blood oxygen saturation levels are supposed to be after tetralogy of fallot?

corrective surgery? My 6 month old son has just been operated and still in ICU and his sats are at 82-89% with 70% oxygen on the ventilator. Is this normal, I thought it would be 95%+?? His sats before fluctuated between 70-85% when inactive and as low as 55% when crying. The pediatrician also told us yesterday that they discovered another hole in his heart so I don't know if this is the cause of the low current sats although they say it isn't, I'm very confused....

1. It is probably the hole, because its not allowing him to get enough Oxygen. Dont worry trust your cardiologist, ask LOTS of questions so you understand whats going on, and if you think they arent right, find another doctor. I hope your son is ok.
