I assume NRP guidelines are the same there as here in the states, but I am not sure. I am an NRP instructor here and I think what the "not suctioning" is referring to no longer suctioning before delivering of the shoulders during meconium delivery. Also, though I think evidence has proven that PPV on room air is sufficent in most cases at delivery, the AAP isn't wanting to stick its neck out that far. As far as oxygen delivery is concerned- term infants that are cyanotic recommendations of 100% or any time PPV is given. It also states that if O2 isn't available to use PPV on room air (??what other option do we have!).
Recommendations on infants less than 32 weeks is to use a blender and pulse ox begining between 21-100% stating there is no evidence study to recommend particular staring point.
