What is the 'hysteria threshold' during a call?

The 'hysteria threshold' refers to the point during a call when the caller becomes so overwhelmed by emotion, typically fear, panic, or distress, that they can no longer effectively follow instructions given by the dispatcher. When a caller reaches this threshold, their ability to communicate clearly and rationally diminishes significantly, making it challenging for the telecommunicator to gather vital information or provide assistance. This understanding is crucial for emergency telecommunicators as they must adapt their communication strategies to manage callers' emotional states and maintain control of the situation. Recognizing when a caller has reached this threshold allows dispatchers to shift their approach to re-establish control and facilitate effective communication, which is essential for an appropriate response to the emergency at hand.
