What is a normal Apgar score?

The Apgar score is a number assigned to a baby right after birth to help the medical team quickly assess the baby’s health. The score is used to help indicate how likely it is that the newborn will need medical intervention.

  • Apgar scores of 7+ are typically considered normal (but not always).
  • Apgar scores of 4 – 6 are below normal. A low score means the baby will likely need medical intervention, which may include resuscitation. The lower the score, the more alert the team should be to the possibility of intervention.
  • Apgar scores of 1 – 3 are critically low.

How Is the Apgar Score Calculated?

A member of the medical team quickly examines the baby and assigns numbers for the different Apgar criteria, so some of the numbers can be largely based on opinion and therefore may not accurately reflect the health of the baby. There certainly are cases in which a baby has a high score but needs urgent medical treatment nonetheless due to birth asphyxia or other birth injuries. In spite of the subjectivity of the Apgar score, however, hospitals universally use it.

What Does the Apgar Score Measure?

  • Appearance/complexion:  Is the baby’s body blue or pale all over, blue at the extremities, or entirely pink?
  • Pulse rate:  Is the baby’s heart rate absent, slow (<100 beats per minute [bpm]) or fast (>100 bpm)?
  • Reflex irritability:  Does the baby have no response to stimulation, does the baby grimace and cry feebly, or does the baby cry and pull away when stimulated?
  • Activity:  Does the baby exhibit no activity, have some flexion (joint movement), or have flexed arms and legs that resist extension?
  • Respiratory effort:  Is the baby breathing, does the baby have a weak, irregular respiratory effort, or is the baby’s cry really strong?

What Do Apgar Scores Mean?

Apgar score assessment is typically done at one and five minutes after birth and may be repeated later if the score remains low.  If the score is low at ten, fifteen, or thirty minutes after birth, there is a significant risk that the baby will suffer long-term brain damage. There is also a significant increase in the risk of the child having cerebral palsy. Higher Apgar scores, however, do not rule out the possibility that the newborn may have a brain injury such as hypoxic-ischemic encephalopathy (HIE). It is important to note that the purpose of the Apgar score is to quickly determine whether a baby needs immediate medical attention; the Apgar score was not devised to make long-term predictions about the newborn’s health.

What Causes a Low Apgar Score?

Listed below are events that can occur during or near the time of birth that, if mismanaged, can cause newborns to have low Apgar scores.  It is important to note that these conditions can injure a baby even without causing low Apgar scores.

What Does a Low Apgar Score Mean? Apgar Scores & Birth Injury

Birth injuries are injuries in a baby caused by an event that occurs during or near the time of delivery.  A lack of oxygen to the baby’s brain (birth asphyxia) is the most common cause of birth injuries.  Birth injuries and birth trauma are associated with permanent brain damage and conditions such as the following:

A common birth injury that does not involve the brain is called a brachial plexus injury or Erb’s palsy.  This occurs when the baby’s shoulder gets caught on the mother’s pelvis during delivery and the physician applies too much force to the baby’s head in an attempt to remove her from the birth canal.  Excessive force can cause the baby’s nerves to stretch or tear, resulting in extreme weakness or paralysis of the affected arm.  Sometimes the baby is stuck for too long in the birth canal, causing head trauma, brain bleeds and/or oxygen deprivation and HIE.
