Final answer:
The normal pulse ox readings of a newborn at 1, 3, and 5 minutes of life are usually between 95-100 percent, indicating normal oxygen saturation levels in the blood.
Step-by-step explanation:
The normal pulse ox readings of a newborn at 1, 3, and 5 minutes of life are usually between 95-100 percent. A pulse oximeter is used to measure the oxygen saturation levels in the blood. Lower percentages reflect hypoxemia, or low blood oxygen, which may indicate a need for medical attention.
