Critical Congenital Heart Disease
In first 48 hours, many of cyanotic congenital heart disease can be easily missed. To avoid that, we shall assess saturation before discharge (at least in one upper and one lower limb). In cyanotic heart disease, saturation will always be less than 95%. If difference in spo2 of upper and lower limbs is more than 5%, then we should get an echo done before discharging the newborn.
