Brief Answer:
cord saturation needs further followup clinically

Detailed Answer:
Hi
Thanks for writing to us.
First I would suggest you that normal saturation for cord vein is 60 to 70. For artery it is much lower. This is because umbilical vein carries oxygenated blood whereas umbilical artery carries deoxygenated blood.
In your son it is marginally lower than normal.
There could be multiple reasons for low saturation
Cord around the neck, maternal factors, etc.
You need to follow up regularly with
Your pediatrician.
Routine followup alone can predict any neurological damage.
Many such kids are normal when followed up
Wishing your child good health.
