Health,
You are totally wrong, OB calls used to be BLS, its changed and became an automatically ALS call, in the system and in Hatzoloh.
Any imminent OB call, will have para,edics on the scene, unless its just a fancy taxi job.
The reason behind the change if protocol is because most women (not chasidishe that always wait till its to late) that call EMS for a delivery usually have poor prenatal care, therefore the protocol demands that Paramedics be called even though its a BLS skill.
I have been reading the arguments of both sides, I really think that this should be discussed with the EMTs and Paramedics that currently do it, see what they have to say.
Again, in new square, because they must have females on the transport (per the rebbes protocol), they have a hard time finding EMTs and Paramedics for OB calls. A serious married person does not want to sit in an ambulance with females, especially if they are part of the crew.
It might solve the issue of “some” female patients being more comfortable, however it raises halachik questions
