What Is Stress?


Topics:

Critical Incident Stress

"CIS occurs when an emergency worker becomes overwhelmed by what they experience at the scene. The ability to cope weakens and the worker suffers physical, cognitive and/or emotional problems."

The Trauma Of A Critical Incident

The alarm sounds. Your heart beats faster. People run. Information comes in bits. Who? What? Where? How serious? You pace and twitch. The ride to the scene lasts forever. Your palms sweat. Adrenaline pumps furiously. Sights, smells, sounds bombard your brain. You feel nauseous, yet you must help. Your emotions shut down. You have a job to do.

So begins a critical incident and the bodily reactions to stress. Sweaty palms, nausea and increased pulse rate are the overt signs of the body's exposure to trauma. Yet the emotional reactions to the sight and sounds of broken bodies, blood and death are usually suppressed.

This conscious effort by the mind to block out the horrifying reality of an incident is a natural, human response. Yet when the emotional stress is so internalized, each new incident has a compounding effect and begins to take its toll. Until, like incredible fatigue, the emergency service worker can no longer respond.

Predetermined critical incidents include:

  • Mass casualty incidents
  • Serious injury or death of an emergency personnel while on duty
  • Suicide of an emergency responder
  • Serious injury or death of a civilian resulting from emergency response activity
  • Death of a child or violence to a child from an adult which affects responders strongly
  • Loss of a life of a patient following extraordinary and prolonged rescue efforts by emergency personnel
  • Incidents which attract extremely unusual or critical media coverage

Delayed Stress

Delayed stress reaction – the stress responses occur hours, days, or weeks after the incident.

Symptoms of Delayed Stress may include:

  • Increased anxiety
  • Depression
  • Increased sensitivity to odors (i.e. blood, urine, burning flesh)

Reminders

Remember that these are NORMAL reactions to abnormal stress. Remember that all debriefings are confidential and that they are NOT a time for criticism.
