What it is
The APGAR score is a rapid, structured description of a newborn’s condition in the first minutes of life. Devised by anaesthesiologist Virginia Apgar in 1953, it scores five clinical signs from 0 to 2 each, for a total of 0–10. It is recorded at 1 and 5 minutes after birth, and then every 5 minutes up to 20 minutes if the 5-minute score is below 7.
The five components
The backronym A-P-G-A-R is the standard memory aid:
| Sign | 0 | 1 | 2 |
|---|---|---|---|
| Appearance (colour) | Blue/pale | Acrocyanosis (pink body, blue extremities) | Completely pink |
| Pulse (heart rate) | Absent | < 100 bpm | ≥ 100 bpm |
| Grimace (reflex irritability) | No response | Grimace | Cough/sneeze/cry |
| Activity (muscle tone) | Limp | Some flexion | Active movement |
| Respiration | Absent | Slow/irregular | Good, crying |
Interpreting the total
- 7–10 — reassuring; routine care.
- 4–6 — moderately abnormal; may need stimulation, airway support, supplemental oxygen.
- 0–3 — low; prompts active resuscitation.
The trend matters more than any single number: a score that climbs from 3 at 1 minute to 8 at 5 minutes reflects an effective response to resuscitation.
When to use it
At every birth, scored by someone not primarily occupied with resuscitating the baby. Crucially, the score never dictates resuscitation — resuscitation is led by heart rate and respiratory effort and begins before the 1-minute APGAR is assigned. The score documents response, it does not gate intervention.
Worked example
A term baby at 1 minute: heart rate 90 (1), slow irregular breathing (1), acrocyanosis (1), some flexion (1), grimace to suction (1) = 5. After drying, stimulation and positive-pressure ventilation, at 5 minutes: HR 140 (2), crying (2), still acrocyanotic (1), active tone (2), cough (2) = 9. The improving trend is the clinically meaningful finding.
Pitfalls and caveats
- It does not diagnose birth asphyxia or predict long-term neurology. A low APGAR alone is not evidence of hypoxic-ischaemic insult; that requires cord gases, encephalopathy assessment and the full clinical picture.
- Confounded by prematurity, maternal sedation/anaesthesia, congenital anomalies and resuscitation itself — a preterm infant can score low from immaturity, not distress.
- Acrocyanosis is normal in the first minutes; do not over-call colour.
- An expanded/assisted APGAR form should record concurrent resuscitative measures (oxygen, CPAP, PPV, intubation, compressions) so the raw number is interpreted in context.
