Final answer:
The normal pre-ductal SpO2 level in a newborn 5 minutes after birth is typically in the range of 95-100 percent according to pulse oximeter readings, which is assessed alongside the Apgar score to determine the overall well-being of the newborn.
Step-by-step explanation:
The targeted pre-ductal SpO2 level 5 minutes after birth varies as a newborn's physiological systems make the transition from intrauterine to extrauterine life. However, a normal pulse oximeter reading ranges from 95-100 percent. Scores are assessed using the Apgar score, which evaluates a newborn's skin color, heart rate, reflexes, muscle tone, and respiration.
Each criterion is assigned a score from 0 to 2. At 5 minutes after birth, scores of 8 or above are considered normal, signaling that the baby has adapted well to life outside the womb. A score below 7 may indicate that medical assistance is needed, and a score below 5 is an emergency situation requiring immediate medical intervention.
