APGAR Score Explained: The Five Signs, the 0–10 Scale, and What It Does (and Doesn't) Tell You

The APGAR score — its five components, the 0–10 scale, 1- and 5-minute timing, and why it is a description of newborn condition, not a diagnosis of asphyxia.

Run it: APGAR Score.

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:

Sign012
Appearance (colour)Blue/paleAcrocyanosis (pink body, blue extremities)Completely pink
Pulse (heart rate)Absent< 100 bpm≥ 100 bpm
Grimace (reflex irritability)No responseGrimaceCough/sneeze/cry
Activity (muscle tone)LimpSome flexionActive movement
RespirationAbsentSlow/irregularGood, crying

Interpreting the total

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.
