What tests are needed to further define Meconium Aspiration?

The presence of meconium is noted when the water is broken either naturally or by the obstetrician. The fluid will have a greenish discoloration. The thickness and degree of discoloration indicates the amount of meconium present. After the baby is born chest X rays will confirm the findings of meconium aspiration if present. A sample of blood called a blood gas along with oxygen-level monitoring (pulse oximeter) will show low oxygen levels and disturbances in lung functioning.
