Can a child be over oxygenated by too fast bagging with ambu bag?

No, a child cannot be over-oxygenated by too fast bagging with an Ambu bag. While using an Ambu bag, the pressure applied during ventilation is relatively low, typically ranging from 15 to 20 cmH2O. This pressure is insufficient to cause over-oxygenation or oxygen toxicity.

Over-oxygenation, which is a rare condition, occurs when the partial pressure of oxygen in the blood (PaO2) exceeds normal levels, usually above 300 mmHg. It can lead to a range of adverse effects, including oxidative stress, lung damage, and central nervous system toxicity. However, these effects are typically seen with prolonged exposure to high oxygen concentrations, not with brief periods of bagging with an Ambu bag.
