If you’re a new parent, you may have come across the term “Apgar score” in your readings. This concept can understandably induce a bit of anxiety for new moms and dads. Here’s a straightforward overview of the Apgar scale and its significance for your newborn’s health.

Understanding the Apgar Test

Developed in 1952 by Dr. Virginia Apgar, the Apgar test is a quick method for evaluating a newborn’s health immediately after birth. The American Academy of Pediatrics states that this test assesses several critical factors, including the baby’s heart rate and muscle tone, to determine if any urgent medical care is necessary. The name “Apgar” serves as a mnemonic for the five key areas assessed:

  • Appearance (skin color)
  • Pulse (heart rate)
  • Grimace response (reflexes)
  • Activity (muscle tone)
  • Respiration (breathing rate and effort)

A healthcare provider, such as a doctor or midwife, conducts this evaluation at one minute post-delivery to gauge how well the baby has handled the birthing process. A second test is performed five minutes later to see how well the baby is adapting to life outside the womb.

How Is the Apgar Score Calculated?

The Apgar score consists of five categories that are individually scored from zero to two, depending on the observations made by the healthcare professional. The total score ranges from one to ten. Here’s how each category is evaluated, according to MedlinePlus:

  • Breathing Effort:
    • 0: Not breathing
    • 1: Slow or irregular breaths
    • 2: Good crying
  • Heart Rate:
    • 0: No heartbeat
    • 1: Less than 100 beats per minute
    • 2: Over 100 beats per minute
  • Muscle Tone:
    • 0: Limp and floppy
    • 1: Some muscle tone
    • 2: Active movement
  • Grimace Response (Reflex Irritability):
    • 0: No response
    • 1: Grimacing
    • 2: Grimacing with a cough, sneeze, or vigorous cry
  • Skin Color:
    • 0: Pale or blue
    • 1: Pink body, blue extremities
    • 2: Completely pink

What Is a Normal Apgar Score?

A typical Apgar score falls between seven and nine, indicating good health. Rarely do newborns achieve a perfect score of ten, as it’s common for them to have bluish extremities right after birth, which is not a cause for concern.

What Does an Apgar Score of 6 Indicate?

Scores between four and six are considered abnormal and may necessitate medical intervention. While a score in this range indicates that the newborn is having some difficulty adjusting to life outside the womb, prompt care from a pediatrician can often resolve the issues. Scores of seven and above are generally reassuring.

Causes of a Low Apgar Score

Scores below seven suggest that the baby is still acclimating to life after birth. Difficult deliveries, including C-sections or fluid in the baby’s airway, often lead to lower scores. Treatment usually involves providing oxygen, clearing the airway, and stimulating the baby to help establish a healthy heart rate. It’s worth noting that many infants with low scores at one minute will show improvement by the five-minute assessment.

Management of Babies with Low Apgar Scores

A newborn with a low Apgar score may struggle with breathing. Scores below seven are often linked to neonatal asphyxia, prompting doctors to provide necessary oxygen and airway clearance. Resuscitation and lung stimulation may also be employed to assist the baby in breathing.

Does Meconium Aspiration Affect the Apgar Score?

Meconium aspiration occurs when a newborn inhales a mixture of meconium and amniotic fluid during delivery. This condition commonly results in Apgar scores of seven or lower within the first few minutes post-birth due to the added stress on the baby’s body.
