What is the apgar score that indicates a life-threatening situaton that requires emergency care?

An Apgar score of 3 or lower indicates a life-threatening situation that requires immediate emergency care for a newborn. The Apgar score assesses five criteria: heart rate, respiratory effort, muscle tone, reflex response, and skin color, each rated from 0 to 2. A low score suggests the newborn may be in distress and needs urgent medical attention.
