As soon as a baby is born, s/he is forced to make major changes within seconds. The APGAR scoring system was developed so that doctors, such as obstetricians, and hospital nurses can rapidly asses how a newborn is adjusting to life outside of the womb, including evaluation of heart rate, respiration, muscle tone, reflex irritability and skin color.
APGARs are commonly assessed at 1 minute and 5 minutes after birth. Generally, the 1 minute APGAR score is an evaluation of how the baby tolerated the birth process; whereas, the 5 minute score is an evaluation of how the baby is adapting to his/her new environment. Where birth complications lead to a low APGAR score, doctors may also perform a 10 minute assessment.
An APGAR score below 7 is considered low. 10-17% of children with a low APGAR score will go on to develop cerebral palsy. Reasons for a low APGAR score include hypoxia (lack of oxygen), ischemia (lack of blood supply), umbilical cord compression, and fetal distress commonly marked by fetal heart rate decelerations.
