How long can a newborn be disconnected from the oxygen machine after asphyxia?

Patient's question:

The baby doesn't understand what the reason is, suddenly experiencing rapid breathing, and was urgently sent to the hospital for rescue. Now, the baby is still in a state of asphyxiation, supported by an oxygen machine. The doctor said they are doing their best to save the baby, but after a day, there has been no improvement. How long can an oxygen machine be used for a newborn in asphyxiation?

Doctor's answer:

When newborns suffer from severe asphyxia, the degree of cerebral ischemia and hypoxia is relatively severe. It can cause varying degrees of cerebral cell edema, apoptosis, and necrosis, leading to different levels of sequelae. However, during the neonatal period, babies have a strong self-healing ability, including good compensatory capacity for the development of brain cells, resulting in significant differences in prognosis. Oxygenation is one of the best ways to rescue severe asphyxia. However, excessive oxygenation can also pose certain risks. Generally, the duration of continuous oxygenation should not exceed 24 hours to avoid eye damage. If the child has respiratory pauses, the priority should still be to save the life.
