Introduction
• Patient assessment: problem-oriented
evaluation of patient; establishing
priorities of care.
• Patient's condition determines
components you use; how to use them.

Introduction
• Proficiency in performing patient
assessment will determine your ability
to deliver highest quality of prehospital
advanced life support (ALS).

Paramedic Care: Principles & Practice, 4th Ed.
Scene Size-Up
• First stage of every emergency call.
• Ensure safe environment.
• Take necessary precautions for
personal protection.
• Determine what resources needed.
• Locate all patients.
• Assess mechanism of injury (MOI) or
nature of medical illness.

Paramedic Care: Principles & Practice, 4th Ed.
Primary Assessment
• Determine whether patient “looks dead
or doesn't look dead.”
• If patient looks dead, quickly assess
responsiveness and breathing.
• If pulse absent, begin chest
compressions immediately.
• If patient shows signs of life, conduct
primary assessment (ABC).

• Do not delay transport for detailed
assessments and procedures.

Secondary Assessment
• Vital signs, followed by focused history
and physical exam.
• Based on primary assessment and
patient's chief complaint.
• Includes monitoring technology.

• Physical signs of trauma confirm index
of suspicion.
• If in doubt, transport patient to medical
facility without delay; always best to
err on side of precaution.
