ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training perspective You & your EMT partner respond with an engine company to a “rollover accident” 3 of the girls are ambulatory, you find that a small sedan carry 4 college-aged girls has rolled over.

ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training perspective 3 of the girls are ambulatory; the 4th is trapped, with her hips lying under the car. She is unresponsive to deep pain & is lying on her side. Her skin is pale & warm. Her respirations are shallow at 12/ min & her pulse is irregular & difficult to palpate at 88 beats/min. The engine company can safely remove her in 10 minutes 3 of the girls are ambulatory; the 4th is trapped, with her hips lying under the car. She is unresponsive to deep pain & is lying on her side.

ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training pathophysiology

ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training Pathophysiology Ventilatory support –Minute volume = tidal x respiratory rate –Tidal volume is the lung volume representing the normal volume of air displaced between normal inspiration and expiration when extra effort is not applied. Typical values are around 500ml or 7ml/kg bodyweight Ventilatory support –Minute volume = tidal x respiratory rate –Tidal volume is the lung volume representing the normal volume of air displaced between normal inspiration and expiration when extra effort is not applied. Typical values are around 500ml or 7ml/kg bodyweight

ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training Epidemiology Ventilatory support can be for a deficit of tidal volume or rate Tidal volume that is too low is problematic Rate that is too high or too low is problematic Ventilatory support can be for a deficit of tidal volume or rate Tidal volume that is too low is problematic Rate that is too high or too low is problematic

ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training Epidemiology Ventilatory support is usually achieved using –BVM with or without adjuncts (NPA or OPA) –Advanced airway insert: King or Combitube –CPAP –Transtracheal Jet Insufflation Always be ready to suction Ventilatory support is usually achieved using –BVM with or without adjuncts (NPA or OPA) –Advanced airway insert: King or Combitube –CPAP –Transtracheal Jet Insufflation Always be ready to suction
