The final extent of any traumatic event may never be known or realistically estimated in terms of loss,bereavement, mourning and grief. In the aftermath of any critical incident, psychological reactions are quite common and are quite predictable. Critical Incident Stress Debriefing or CISD and the management of traumatic reactions by survivors can be a valuable tool following a life-threatening event.
Clinically, traumatic events and their impact on individuals are fairly predictable. When a person has been “exposed” to a critical incident, either briefly or long-term, this exposure can have a considerable impact on their global functioning.
