Step-by-step explanation:
A newborn typically achieves an SpO2 >90% within 1-2 minutes. The Apgar score, which assesses the newborn's overall wellbeing, includes criteria such as skin color, heart rate, reflex, muscle tone, and respiration. Scores are taken at 1 minute and again at 5 minutes after birth. A score of 8 or above is considered normal.
