child’s symptoms depend on the size of his or her septal openings. The larger the
openings, the more blood is able to pass through them. This can overload your child's
heart and lungs. This means that your child’s symptoms may be more severe.
Over time, the pressure in your child’s lungs will force blood back to his or her heart. This blood has low oxygen levels, and it’s sent to the rest body. This causes your child’s lips, nailbeds, and skin to turn blue (cyanosis).
