The APGAR score is the most widely used rapid clinical assessment of a newborn’s condition in the first minutes after birth. Developed by the American anaesthesiologist Dr Virginia Apgar in 1952 and standardised by the American Academy of Pediatrics (AAP) and the American College of Obstetricians and Gynecologists (ACOG), it gives a single number — 0 to 10 — that summarises five observable signs: skin colour, heart rate, reflex response, muscle tone, and breathing effort.
Each of the five criteria is scored 0, 1, or 2 by a trained clinician, and the five scores are summed. The assessment is made at 1 minute and 5 minutes after birth. If the 5-minute score remains below 7, further assessments are made every 5 minutes up to 20 minutes. The 1-minute score guides immediate interventions such as supplemental oxygen or gentle stimulation. The 5-minute score is a stronger indicator of neonatal outcome and is the one most commonly reported in clinical records.
How the score is calculated
The formula is simply a sum of five independent subscores:
Total = Appearance + Pulse + Grimace + Activity + Respiration
Each subscore is 0, 1, or 2, giving a maximum of 10. The five-letter mnemonic A-P-G-A-R maps directly:
| Letter | Criterion | Score 0 | Score 1 | Score 2 |
|---|---|---|---|---|
| A | Appearance (skin colour) | Blue or pale all over | Blue extremities, pink body | Completely pink |
| P | Pulse (heart rate) | Absent | Below 100 bpm | 100 bpm or above |
| G | Grimace (reflex irritability) | No response to stimulation | Grimace or weak cry | Cough, sneeze, or vigorous cry |
| A | Activity (muscle tone) | Limp | Some flexion of limbs | Active motion, good flexion |
| R | Respiration | Absent | Weak, irregular, or gasping | Strong cry, regular breathing |
Interpretation is as follows: a total of 7–10 is normal and reassuring; 4–6 indicates moderate concern and the baby may need some assistance; 0–3 is a critically low score requiring immediate resuscitation.
Worked example
A term baby is delivered and assessed at 1 minute:
- Appearance: body pink, extremities still blue → 1
- Pulse: heart rate measured at 120 bpm → 2
- Grimace: cries vigorously when suctioned → 2
- Activity: good flexion, arms and legs moving → 2
- Respiration: strong regular cry → 2
Total at 1 minute: 9/10 — normal, reassuring.
By 5 minutes the extremities have also pinked up, bringing the Appearance score to 2, giving a 5-minute score of 10/10.
A baby with significant birth depression might score 1+1+1+0+1 = 4/10, triggering oxygen administration and closer monitoring. A score of 1+0+0+0+0 = 1/10 would prompt full resuscitation measures immediately.
Note that bluish extremities (acrocyanosis) in the first 1–2 minutes of life are entirely normal for a healthy baby, so a 1-minute score of 9 is common and does not indicate any problem.
Educational use only. This calculator is a reference and teaching tool. APGAR assessment must be performed by a trained healthcare professional who is physically present and observing the baby. The score does not replace clinical judgement, and a low score must be interpreted alongside all other clinical findings. Always defer to the medical team caring for the mother and newborn.
