    31. 31. Understanding Drowning: 2013 Airway ▫ Ventilate / Oxygenate – Pediatric – Laryngospasm – Airway obstruction? – Foam, Sand, Mud, Del Taco – Vomitus – 86% of Drowning resuscitations Introduction Epidemiology Definition Pathophysiology Treatment Disposition Review
    32. 32. Understanding Drowning: 2013 Introduction Epidemiology Definition Pathophysiology Treatment Disposition Review
    33. 33. Understanding Drowning: 2013 In Water Resuscitation ▫ 3X Increased Survival Introduction Epidemiology Definition Pathophysiology Treatment Disposition Review
    34. 34. Understanding Drowning: 2013 Spinal ImmobilizationIntroduction Epidemiology Definition Pathophysiology Treatment Disposition Review Prevalence of C-spine injuries associated with drowning incidents is 1 % Usually clear signs of trauma or obvious evidence of diving/high velocity trauma Universal immobilization unnecessary, should not delay resuscitation
    35. 35. Understanding Drowning: 2013 Automated External Defibrillators ▫ Dysrhythmias secondary to hypoxia ▫ AED use safe in wet environments • Avoid direct contact with patient • Place pads firmly on chest ▫ Should not delay ventilations Introduction Epidemiology Definition Pathophysiology Treatment Disposition Review

    37. 37. Understanding Drowning: 2013 Understand definition of drowning ▫ Process, not an outcome Appreciate epidemiology ▫ Highly prevalent worldwide, children 4 Emergent Management ▫ Rapid O2 O2 O2, warm pt to 94 F, anticipate vomitus, ignore foam ▫ Hypoxic vs Cardiac cause of arrest When to Transport ▫ ALL Symptomatic patients Don’t blow smoke up pt’s (or colleagues) asses Introduction Epidemiology Definition Pathophysiology Treatment Disposition Review
