Which type of call requires the EMD to instruct the caller on controlling bleeding?

In the context of emergency medical dispatch, trauma emergencies involve situations where there may be severe injuries, including those that cause significant bleeding. In such cases, the dispatcher must provide clear and specific instructions to the caller on how to control bleeding effectively. This could include techniques such as applying direct pressure, elevating the injury above the level of the heart, or using a tourniquet if necessary.

In contrast, cardiac emergencies primarily involve issues related to heart function and may not typically involve bleeding, making the need for bleeding control instruction less relevant. Respiratory emergencies generally pertain to breathing difficulties, such as asthma attacks or choking, where the focus is on maintaining airway patency and providing support. Psychiatric emergencies involve mental health crises, which do not generally require interventions related to bleeding management. Therefore, the central focus of providing instruction on controlling bleeding distinctly aligns with trauma emergencies.
