10. Mechanism of Injury and Kinematics Mechanism=detailed cause or type of event Mechanism=detailed cause or type of event Kinematics = physics of trauma, how is energy dispersed Kinematics = physics of trauma, how is energy dispersed Part of primary survey…listen to prehospital caregivers Part of primary survey…listen to prehospital caregivers

11. Fundamentals of Initial Resuscitation

12. Concepts Assessment and resuscitation occur simultaneously Assessment and resuscitation occur simultaneously Reassess frequently Reassess frequently Establish priorities and anticipate needs Establish priorities and anticipate needs Life over limb Life over limb Preparedness, organization, communication Preparedness, organization, communication Someone must be in control Someone must be in control Do no further harm Do no further harm If condition progressively worsens…definitive care is needed. If condition progressively worsens…definitive care is needed.

13. Goals of Resuscitation Oxygenation of vital tissues….it’s all about perfusion Oxygenation of vital tissues….it’s all about perfusion
