Paramedic Care: Principles & Practice Fourth Edition Volume 3: Patient Assessment CHAPTER 7 Patient Assessment in the Field Standard • Assessment ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Competency • Integrate scene and patient assessment findings with knowledge of epidemiology and pathophysiology to form a field impression. • This includes developing a list of differential diagnoses through clinical reasoning to modify the assessment and formulate a treatment plan. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Introduction • Patient assessment: problem-oriented evaluation of patient; establishing priorities of care. • Patient's condition determines components you use; how to use them. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Introduction • Proficiency in performing patient assessment will determine your ability to deliver highest quality of prehospital advanced life support (ALS). ©2013 Pearson Education, Inc. 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. ©2013 Pearson Education, Inc. 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). ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Primary Assessment • Steps of Primary Assessment – Form general impression – Stabilize cervical spine as needed – Assess baseline mental status – Assess airway – Assess breathing – Assess circulation – Assign priority ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Manually stabilize the head and neck on first patient contact. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Primary Assessment • Should take less than 1 minute, unless you intervene with lifesaving measures. • Do not delay transport for detailed assessments and procedures. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Secondary Assessment • Vital signs, followed by focused history and physical exam. • Based on primary assessment and patient's chief complaint. • Includes monitoring technology. ©2013 Pearson Education, Inc.
