Unit 3: Disasters Flashcards
Disaster
- causes immeasurable amount of pain and suffering
- a serious disruption of the functioning of a community or or a society causing widespread human, material, economic or environmental losses which exceed the ability of the affected community or society to cope using its own resources
- a disaster occurs when needs exceed resources following an event
- can be natural or man-made
Federal Emergency Management Agency (FEMA) Definition of a Disaster
an occurrence of a natural catastrophe, technological accident, or human event that has resulted in severe property damage, death, and/or multiple injuries
Disaster Events are defined by 3 characteristics
- An event of destructive magnitude;
- That kills, injures, or causes human suffering to a significant number of people or the environment
- That requires the need for external assistance
Mass Casualty Incident (MCI)
- any large-scale event in which emergency medical resources such as supplies, medical/rescue personnel, or equipment are overwhelmed by the number and severity of casualties, thus requiring prioritization of medical care by triage
- when the healthcare needs exceed the healthcare resources
- All MCIs are disasters, but not all disasters are MCIs
Casualty
includes all persons who are ill, injured, missing, or dead as the result of the incident
Incident
an event that requires scene or casualty management
The goal of the response to any mass casualty incident (MCI)
“do the greatest good for the greatest number of people”
-this can mean delaying care to selected people who have little hope of survival or would consume too many resources
Triage
process of placing the right patient in the right place at the right time to receive the right level of care
-tagged with a corresponding triage tag
Goal of Daily Triage
identify and treat the most seriously ill or injured first
Triage Models
- Simple Triage and Rapid Treatment (START)
- Sort, Assess, Life-saving Interventions, Treatment, and/or Transport (SALT)
Simple Triage and Rapid Treatment (START)
- completed in 60 seconds or less
- based on respirations, perfusion (or pulse), and mental status “RPM”
- begins by directing all patients who are ambulatory to move to a safe area; tagged “green”, or “minor”
How START Model Works
- begins by directing all patients who are ambulatory to move to a safe area; tagged “green”, or “minor”; capable of ambulating and understanding directions and have adequate perfusion to follow commands and stay upright
- triage then continues for the remainder of the patients
- patients with no spontaneous respirations receive airway repositioning
- if remain apneic, tagged “deceased” by using a black label and receive no further care or interventions
- if repositioning the airway initiates respirations; tagged “red” or “immediate”
- patients w/ respirations greater than 30 breaths/min or a capillary refill longer than 2 seconds or who are unable to to follow simple directions are tagged “immediate” or “red”
- the remaining patients are tagged “delayed” and given a yellow tag
The START model allows for what 2 Interventions during the Triage Process
- direct pressure to control bleeding
2. basic airway-opening maneuvers
Sort, Assess, Life-saving Interventions, Treatment, and/or Transport (SALT)
- can triage both adults and children
- first step is to address the “walking wounded”
- second step, make lifesaving interventions before assigning to a triage category
- lastly, triage category assigned (delayed, immediate, or expectant)
How SALT method Works
- Address the “walking wounded”
- able to walk are prioritized last
- cannot follow a command or have an obvious life-threat are prioritized first
- can follow a command but are unable to walk, prioritized second - Make lifesaving interventions
- control of major hemorrhage, opening the airway and providing two breaths for child casualties, decompression of tension pneumothorax, and use of auto injector antidotes - Triage (delayed, immediate, expectant)
- based on breathing, peripheral pulses, respiratory distress, and hemorrhage control
SALT Method: Expectant category
- the patient may have a life-threatening injury, but current resources are not available to meet the need
- as resources become available, this “expectant” category of patients should be re-evaluated frequently
Connection Check: Which of the following statements best explains the relationship between an MCI and a disaster?

B. All mass casualty events are disasters
C. Mass casualty events are natural disasters
D. Mass casualty events are man-made disasters
B. All mass casualty events are disasters
