What is the Apgar score, and what are its five components?

The Apgar score assesses a newborn's condition at 1 and 5 minutes (and 10 if low), scoring five signs 0, 1, or 2 (maximum 10):

• Appearance (colour), Pulse (heart rate), Grimace (reflex irritability to stimulation), Activity (muscle tone), Respiration

A higher score indicates better condition; a low score prompts resuscitation/closer assessment.

Clinical relevance. The Apgar score (5 components, 0-2 each) standardises rapid newborn assessment and flags the need for resuscitation.

More Detail

The Apgar score

The Apgar score is a quick standardised assessment of the newborn's condition.

When

• Assessed at 1 and 5 minutes after birth (and at 10 minutes if the 5-minute score is low).

The five components (each scored 0-2)

• Appearance (colour) - 0 blue/pale, 1 body pink with blue extremities, 2 completely pink.
• Pulse (heart rate) - 0 absent, 1 <100 bpm, 2 >=100 bpm.
• Grimace (reflex irritability to stimulation) - 0 none, 1 grimace, 2 cry/cough.
• Activity (muscle tone) - 0 limp/floppy, 1 some flexion, 2 active motion/flexed limbs.
• Respiration - 0 absent, 1 slow/irregular/weak cry, 2 good/strong cry.

Interpretation

• Maximum 10; a higher score = better condition.
• A low Apgar score (especially persistently low) prompts resuscitation and closer assessment; it reflects the need for intervention rather than predicting long-term outcome alone.
