I'm a bit late, but I'll weigh in for posterity!
I have actually taken both Karen Strange's (in Nov 2008) and Ricci Bohaboy's (June 2010) NRP trainings. I felt that Karen's presentation was geared in a more customized way toward home birth midwifery. She definitely puts together a package of information about resuscitation in the context of the baby's experience of birth and does not worry too much about presenting American NRP by the book. She incorporates parts of British Newborn Life Support, research from other realms (on neonatal psychology, maternal psychology, etc), and birth trauma healing methodology, all in a one day training.
My impression was that Karen wanted us to be calm, centered, and communicating with the baby while performing resuscitation, not "apologizing" before starting! For babies that are vigorous, just not breathing, she did advocate waiting a moment before jumping in with the routine care. It isn't my impression that it applied to babies in obvious distress (limp, pale, etc). I am one of those people who believes that the baby IS a sentient being, even exquisitely sensitive, so treating the baby as a participant in his or her own resuscitation isn't a foreign idea. Some midwives who were in my training with Karen did scoff at all the focus on the baby's experience (ie, "It's going to be so much better than at the hospital anyway, don'tcha know!")
Ricci, though a home birth midwife, has a long history of working in medical settings, and teaches the material as packaged by NRP (even using the video provided). I also got the impression that she sees oxygen as a great good (she added in oxygen therapy for our group--how to choose and use oxygen equipment properly), whereas Karen seemed to downplay the importance of oxygen. With Ricci we did practice a wider range of interventions (infant bulb suctioning, DeLee suctioning, infant O2 mask use, and orogastric tube), and someone in our group also certified to do intubation because Ricci was able to supervise it. However, Ricci had only two manikins for our group, meaning 3-4 people were sharing a manikin (vs 1-2trainees/ CPR manikin in Karen's much larger class). However, one of Ricci's babies was an actual NRP manikin, which could be intubated/DeLee suctioned, etc, which was useful. I don't know if Ricci has more manikins and just didn't bring them. I also felt that the time management aspect of Ricci's training was off. We spent too much time watching the videos together, going over the material step-by-step, and less time than I would have liked practicing with the manikins, even though it was a 2 day training!
In short, I felt Ricci did a fine job of training midwives to do resuscitation by NRP standards thoroughly and accurately. Karen's class, however, was deeply enlightening, far beyond what one would expect of an NRP training.
