Adequate Breathing Provide oxygen Subtle deterioration of breathing Caution! –Coma –SCI –Chest trauma
Inadequate Breathing LookListen
Inadequate Breathing FeelAdjuncts
Adequate oxygenation Requires –Oxygen –Definitive airway –Ventilation Caution –Protect C-spine
Airway Maintenance Chin lift Jaw thrust Oral airway Nasal airway
Definitive Airway Need for Airway –Coma –Maxillofacial injury –Aspiration –Airway injury Need for Breathing –Apnea –Hypoxia –Hypercapnia –Brain injury Definitive aw = cuffed tube in trachea
Definitive Airway Orotracheal Nasotracheal Surgical airway
Right Bronchial intubation Xray of right bronchial intubation
RSI Be prepared for surgical airway Requires skill and training Urgency must justify risk
Surgical Airway Indications –Inability to intubate the trachea –Maxillofacial trauma –Neck injury Methods –Needle –Surgical
Defnintive Airway: Immediate need: Apneic patient Protect c spin Oxgyenate ventilate Orotracheal intubation (No nasotracheal intubation b/c of apnea) If unable to intubate surgical airway
Defnintive Airway: Immediate need: Breathing patient Protect c spine Oxgyenate ventilate Oro or nasotracheal intubation, maintain c- spine position If unable to intubate surgical airway
Defnintive Airway: Immediate need: Maxillofacial trauma Protect c spine Oxgyenate and ventilate as needed If unable to intubate surgical airway
Oxygenate and Ventilate Goal = achieve maximal cellular oxygen O2 at L/min Tight fitting mask with resevoir Ventilate Avoid prolonged intubation attempts
Monitor Oxygenation Pulsoximeter –Measures oxygenated hemoglobin Utility –Difficult intubation –Transport Pa02 vs sat –90 = 100% –60 = 90% –30 – 60%
