I was instructed in a hospital-based class in a major children's hospital about 10 years ago to give blow-by oxygen with the end of the corrugated reservoir tubing coming off the end of a self-inflating ambu bag when it is attached to an oxygen source. I am in search of evidenced-based material to support this practice elsewhere. This hospital still practices this method. The instructor who taught this is no longer there. Have been able to come up with material that states BBO2 cannot be given with a self-inflating bag itself. Anyone use this practice? Have anything to back it up?

Please use the links and see the different circuits used.

As 100 FiO2 is no longer recommended to start bag and mask ventilation in neonates, it seems not reasonable to use corrugated tubes attached to the ambu to increase FiO2. I make myself the same question that you. A well known colleague currently working in Melbourne conducted an interesting study about this topic. You can read the paper : Arch Dis Child Fetal Neonat ed 2010;95(5): 315-19. I can send the full text to you if you have not free access to it.
