oxygen saturation for pediatric cardiology

[deepurple]

Many case for paediatric congenital cardiac disease. When i'm doing 4hourly observation including pulse oximetry for preoperative and postoperative cases, i'm confused about the oximetry reading for congenital cardiac cases. I'd been searching for oximetry reading for congenital case but couldn't find up until now. Someone can help me where i can find information for oximtery reading for congenital cases.
