The problem here is that syntocinon is a prescription only drug. As is vitamin K. In hospital it is given as part of a standing order, and hospital midwives have access to it as needed, but this is obviously not the case for independent midwives. Yes, most midwives carry it, but unless the woman can get a prescription for it, thry only have two options - either obtain it from a hospital (which is obviously theft, and against the law) or not use it and transfer in at the first sign of bleeding. Oxygen, on the other hand, does not require a prescription and is therefore much easier to obtain.
