I think the bigger issue is why is an individual patient going by ambulance than other modes of transport. If a true medical necessity for transport by ambulance is needed, then it's important that the providers on board know how to handle contingencies. On the other hand, if it's a pure horizontal taxi transport, then the question is why does the person need an ambulance at all versus other modes of transportation? A trach, by itself, isn't a reason for ambulance transport, little less a CCT or paramedic transport. However, a patient with a trach and an appropriate medical need for ambulance transport very easily begins to exceed the capabilities of an EMT level ambulance.
