Which type of call requires radio communication to receiving facility?

Radio communication to the receiving facility is typically required for High Priority or Code 3 responses, which involve urgent situations where rapid transportation and immediate medical intervention may be necessary. In these high-priority calls, it's imperative to inform the hospital of the patient’s condition and any interventions that have been performed prior to arrival. This preparation enables the receiving facility to mobilize the appropriate resources, such as specialists or additional equipment, in anticipation of the patient's needs.

In contrast, other scenarios like Code 2 (which is generally classified as an urgent but not life-threatening situation) or calls concerning specific patient conditions like ETOH (alcohol intoxication) and fever may not necessitate the same immediate communication with the receiving facility, as the urgency of the case may not require advanced preparations or resources as much as a Code 3 call would.
