APGAR Score

Newborn APGAR Score

Appearance

Skin Color

Pulse

Heart Rate

Grimace

Reflex Irritability

Activity

Muscle Tone

Respiration

Breathing

Observation Score

0/10

SEVERELY DEPRESSED • ESCALATE

Score at 1 and 5 minutes. If 5-minute score < 7, continue scoring every 5 minutes up to 20 minutes. APGAR reflects clinical status but does not predict individual long-term neurological outcome.

When to Use

Primary Clinical Uses

  • Standardised rapid assessment of a newborn's physical condition immediately after birth
  • Documenting transition to extrauterine life at 1 and 5 minutes post-partum
  • Guiding the potential need for escalated monitoring or prolonged observation

When NOT to Use

Do NOT use the APGAR score to determine the initial need for neonatal resuscitation. Resuscitation (if needed) must begin immediately at birth before the 1-minute score is assigned based on the infant's initial tone, breathing, and heart rate.

Practical Pearls

Key Strengths

  • Rapid, non-invasive, and universally standardized communication tool among providers
  • Requires zero equipment aside from a stethoscope and a timer

Known Limitations

  • Highly subjective, especially regarding color (Appearance) and tone (Activity)
  • Color interpretation can be biased and less reliable in neonates with darker skin tones
  • Does not reliably predict long-term neurodevelopmental outcomes (e.g., cerebral palsy)
  • Prematurity, maternal sedation/anesthesia, and congenital anomalies can artificially lower the score independently of asphyxia

Next Steps

Score 7–10 — Reassuring

  • Continue routine post-natal care
  • Proceed with standard newborn assessment and maternal bonding

Score 4–6 — Moderately Abnormal

  • Provide stimulation and clear airway as needed
  • Apply supplemental oxygen if clinically indicated
  • Repeat score every 5 minutes (up to 20 mins) if the score remains below 7

Score 0–3 — Critically Low

  • Initiate immediate Neonatal Resuscitation Program (NRP) protocols
  • Consider umbilical cord blood gas analysis for objective metabolic assessment
  • Prepare for potential NICU transfer or escalated care

Evidence Base

Original Derivation

A proposal for a new method of evaluation of the newborn infant.

Apgar V.Curr Res Anesth Analg.1953

Current Guidelines

The American Academy of Pediatrics (AAP) and Neonatal Resuscitation Program (NRP) dictate that the APGAR score is a retrospective descriptor of resuscitation efforts, not a trigger. Resuscitation must never be delayed to wait for the 1-minute APGAR.

Background

Dr. Virginia Apgar

Developed in 1952 by Dr. Virginia Apgar, an anesthesiologist at Columbia University. She designed the tool to objectively assess the effects of maternal obstetric anesthesia on newborns, standardizing a previously chaotic post-partum assessment.

The APGAR Acronym

The backronym (Appearance, Pulse, Grimace, Activity, Respiration) was not Dr. Apgar's original naming. It was coined in 1963 by Dr. Joseph Butterfield as a convenient mnemonic for pediatricians and nurses.
