Final answer:
A baby not breathing after stimulation may be in secondary apnea, requiring resuscitation and intubation, and possibly ventilation. This situation is critical and demands prompt medical intervention.
Step-by-step explanation:
If a baby does not begin breathing immediately after being stimulated, he or she is likely in secondary apnea and will require medical intervention. Continued stimulation will not help. In such cases, the standard treatment involves resuscitation and intubation if the infant does not breathe on their own. The infant may need to be placed on a ventilator to mechanically assist with the breathing process. This condition is critical and requires immediate attention from medical professionals equipped to provide respiratory support, and potentially, additional therapies such as the administration of pulmonary surfactant, supplemental oxygen, and assisted ventilation may be necessary.
