Used a Neo-Tee for the first time a couple of nights ago, great product. Had to "bag" the patient for a couple of hours, it worked exactly as advertised.
from NRP 7th protocol, u count ur bagging by this method: bag-2-3, bag-2-3, bag-2-3... and so on bag is when u bagging/put ur finger on the t-piece, 2 and 3 is counting for the next bagging
