Apgar score

Newborn scoring; Delivery - Apgar

Apgar is a quick test performed on a baby at 1 and 5 minutes after birth. The 1-minute score determines how well the baby tolerated the birthing process. The 5-minute score tells the health care provider how well the baby is doing outside the mother's womb.

In rare cases, the test will be done 10 minutes after birth.

Virginia Apgar, MD (1909-1974) introduced the Apgar score in 1952.

How the Test is Performed

The Apgar test is done by a doctor, midwife, or nurse. The provider examines the baby's:

  • Breathing effort
  • Heart rate
  • Muscle tone
  • Reflexes
  • Skin color

Each category is scored with 0, 1, or 2, depending on the observed condition.

Breathing effort:

  • If the infant is not breathing, the respiratory score is 0.
  • If the respirations are slow or irregular, the infant scores 1 for respiratory effort.
  • If the infant cries well, the respiratory score is 2.

Heart rate is evaluated by stethoscope. This is the most important assessment:

  • If there is no heartbeat, the infant scores 0 for heart rate.
  • If heart rate is less than 100 beats per minute, the infant scores 1 for heart rate.
  • If heart rate is greater than 100 beats per minute, the infant scores 2 for heart rate.

Muscle tone:

  • If muscles are loose and floppy, the infant scores 0 for muscle tone.
  • If there is some muscle tone, the infant scores 1.
  • If there is active motion, the infant scores 2 for muscle tone.

Grimace response or reflex irritability is a term describing response to stimulation, such as a mild pinch:

  • If there is no reaction, the infant scores 0 for reflex irritability.
  • If there is grimacing, the infant scores 1 for reflex irritability.
  • If there is grimacing and a cough, sneeze, or vigorous cry, the infant scores 2 for reflex irritability.

Skin color:

  • If the skin color is pale blue, the infant scores 0 for color.
  • If the body is pink and the extremities are blue, the infant scores 1 for color.
  • If the entire body is pink, the infant scores 2 for color.

Why the Test is Performed

This test is done to determine whether a newborn needs help breathing or is having heart trouble.

Normal Results

The Apgar score is based on a total score of 1 to 10. The higher the score, the better the baby is doing after birth.

A score of 7, 8, or 9 is normal and is a sign that the newborn is in good health. A score of 10 is very unusual, since almost all newborns lose 1 point for blue hands and feet, which is normal for after birth.

What Abnormal Results Mean

Any score lower than 7 is a sign that the baby needs medical attention. The lower the score, the more help the baby needs to adjust outside the mother's womb.

Most of the time a low Apgar score is caused by:

  • Difficult birth
  • C-section
  • Fluid in the baby's airway

A baby with a low Apgar score may need:

  • Oxygen and clearing out the airway to help with breathing
  • Physical stimulation to get the heart beating at a healthy rate

Most of the time, a low score at 1 minute is near-normal by 5 minutes.

A lower Apgar score does not mean a child will have serious or long-term health problems. The Apgar score is not designed to predict the future health of the child.

      An evaluation of the newborn's condition is done immediately after delivery and again at five minutes, to determine the APGAR scores. If some cyanosis (bluish skin) is present, the APGAR scores are lower and oxygen may be administered. The oxygen can often be merely blown by the newborn's face, through the mask in front of the infant.

      The newborn is commonly assessed with the APGAR score, a quick test performed at 1 and 5 minutes after birth to determine the physical condition of the newborn. The five categories assessed are heart rate, respiratory effort, muscle tone, reflex irritability, and color. Each of these categories is scored 0, 1, or 2, depending on the observed condition of the newborn.
