Please don’t get carries away with psak.
Each Hatzoloh has their board of rabonim that know the details and are involved in the day to day halachik questions that arise.
So don’t make it seem as if EN have rabonim and Hatzoloh does not, in fact karlsburger ruv is a very controversial rav.
Besides they did not approach the rabonim that run Hatzoloh, nor did they approach Hatzoloh. They only approached the media.
I don’t know why your changing facts, currently in Hatzoloh each OB call is an ALS call, in NY it’s an ALS call, if someone calls 911 medics will show up, they might not transport however they will do the delivery, currently EN only have EMTs which means their care will be on a lower level then if the PT would have called Hatzoloh or 911.
