Phases of Deceleration
1) Deceleration of the vehicle, occurs when the vehicle strikes another object & comes to a stop. 2)
Deceleration of occupant, which starts during sudden braking & continues through the whole crash. 3)
Deceleration of internal organs, that consist of internal organs that continue forward momentum until
they're stopped by anatomical restraints. 4) Secondary collisions, which occur when a vehicle occupant
is hit by objects moving within the vehicle (loose objects). 5) Additional impacts, that the vehicle may
receive when it is hit by a second vehicle or is deflected into another.
Seat Belt Use
All arguments against seat belt use are unfounded.
Primary Blast Injury
, Injuries due to the wave blast itself, usually causing damage to the lungs, eardrums and other
compressible organs (air filled cavities). Burns also may occur.
Secondary Blast Injury
Injuries due to missiles being propelled by blast force (struck by flying debris).
Tertiary Blast Injury
Injuries due to body impact with another object (when a person is hurled by the force against stationary
objects).
Perfusion
Circulation of blood within an organ or tissue in adequate amounts to meet the cells needs.
Autonomic Nervous System
Monitors the body's needs from moment to moment, adjusting the blood flow as required. Maintains
homeostasis & is divided into the parasympathetic & sympathetic components that oppose each other
and keep vital functions in balance.

Decompensated Shock (Phase 2)
AMS, DROP IN BP, thready/absent peripheral pulse, labored or irregular breathing.
