    "description": r"""
Newborn health assessment scoring system performed at 1 and 5 minutes after birth.

The Apgar score sums five categories (0–2 points each):
1. Heart rate
2. Respiratory effort
3. Muscle tone
4. Reflex response
5. Color

Total score ranges from 0 to 10. Higher scores indicate better newborn condition.
