A complete guide to the APGAR score — what each of the five components means, how the score is assessed, what different scores indicate, and what happens when a baby scores low.
The first moments after birth are among the most medically critical in a person's entire life. In the delivery room, clinicians need to rapidly assess whether a newborn is making the expected transition from life inside the womb to independent breathing and circulation — or whether they need help.
The APGAR score is the universal tool used for this assessment. It is simple, quick, and performed without any equipment. In under 60 seconds, it captures five vital signs of newborn wellbeing and converts them into a number that guides the next clinical decision. Every doctor, midwife, and nurse present at a delivery knows it.
It is also a score that parents frequently ask about — and often misunderstand. This guide explains every component clearly, so that both clinicians and parents understand exactly what the APGAR score means.
The APGAR score was developed by Dr Virginia Apgar, an American anaesthesiologist, in 1952. Originally designed to standardise newborn assessment that had previously been inconsistent and subjective, it became one of the most widely adopted clinical tools in medicine.
The name is both an eponym (after Dr Apgar) and a mnemonic — each letter stands for one of the five assessed components. This double meaning makes it easy to remember even under the pressure of a busy delivery room:
Each component is scored 0, 1, or 2, giving a maximum total of 10.
| Component | 0 Signs | 1 Signs | 2 Signs |
|---|---|---|---|
| A — Appearance Skin colour |
Blue or pale all over | Body pink, extremities blue (acrocyanosis) | Pink all over |
| P — Pulse Heart rate |
Absent (no heartbeat) | Less than 100 beats/min | 100 beats/min or more |
| G — Grimace Reflex irritability |
No response to stimulation | Grimace or frown only | Cry, cough, or sneeze |
| A — Activity Muscle tone |
Limp, no movement | Some flexion of arms and legs | Active motion, well-flexed limbs |
| R — Respiration Breathing effort |
Absent (not breathing) | Weak, irregular, or gasping | Strong cry, regular breathing |

The APGAR score is assessed at three standardised time points:
| Time Point | Purpose | Clinical Significance |
|---|---|---|
| 1 Minute | Reflects the baby's condition at birth and immediate response to delivery | Guides whether immediate resuscitation is needed |
| 5 Minutes | Reflects the response to initial resuscitation (if any was given) | Most clinically predictive score for outcomes |
| 10 Minutes | Assessed only if the 5-minute score is < 7 | Persistent low score warrants escalation and investigation |
⚠️ Important for parents: A score of 7 or above is normal and reassuring. A score less than 10 — especially at 1 minute — does not mean something is permanently wrong with your baby. Most babies with low 1-minute scores recover completely with brief support. The 5-minute score is a much stronger indicator of outcome.
Baby: Born at 39 weeks by emergency C-section, cord around neck once (loose nuchal cord). Assessed at 1 minute.
1-Minute APGAR Score: 6
5-Minute APGAR Score: 9 (after drying, stimulation, and brief supplemental oxygen)
A 1-minute score of 6 prompted gentle stimulation and oxygen. By 5 minutes the baby had a strong cry, pink colour, and good tone — scoring 9. This is a common and reassuring trajectory. The baby required no further intervention.
A low APGAR score — particularly at 5 minutes — triggers the Neonatal Resuscitation Protocol (NRP). The steps follow the acronym ABC:
Position the baby with the neck slightly extended (neutral or "sniffing" position). Clear the airway with gentle suction if meconium or secretions are present. Stimulate the baby by rubbing the back or flicking the soles of the feet.
If the baby is not breathing adequately, provide positive pressure ventilation (PPV) using a bag-mask device with 21% oxygen (room air) initially in term babies. Assess for chest rise. If there is no chest rise, reposition the airway and retry. Intubation may be required if PPV is ineffective.
If the heart rate remains below 60 bpm despite 30 seconds of effective PPV, begin chest compressions at a ratio of 3:1 (3 compressions to 1 breath), at a rate of 90 compressions + 30 breaths per minute. Adrenaline may be required if the heart rate remains unresponsive.
This is one of the most common and important questions parents ask. The answer is nuanced:
💡 For parents: A 5-minute APGAR score of 7 or above is reassuring even if the 1-minute score was low. If your baby needed any resuscitation at birth, ask your paediatrician what the 5-minute score was and what follow-up is planned.
The APGAR score is less reliable in premature infants. A preterm baby may score low simply due to physiological immaturity — reduced muscle tone, thin skin appearing pale or blue, and weak cry — rather than true perinatal compromise. For this reason, many neonatal units use the expanded APGAR score or colour-adjusted assessments for preterm babies, particularly those below 28 weeks' gestation.
Gestational age and birth weight provide important additional context when interpreting APGAR scores in premature newborns.
