Chapter 2
Ensure adequacy of the airway Confirm adequacy of ventilation Define “definitive airway” Maintain adequate oxygenation in all phases of airway management
How do I know the airway is adequate? How do I know ventilation is adequate? How do I know oxygenation is adequate? What are the pitfalls?
…the patient talks clearly? Management: observation and selective intubation High index of suspicion with: ◦ Maxillofacial injuries ◦ Soft-tissue injury of neck ◦ Facial or neck burns
…the patient is hoarse? Possible: ◦ Laryngeal injury ◦ Laryngeal/tracheal burn Management: Evaluate and perform ◦ Careful endoscopic exam ◦ Careful and gentle intubation ◦ Surgical airway?
…the patient cannot respond? GCS score <9 Obstruction due to: ◦ Tongue ◦ Aspiration ◦ Foreign body ◦ Maxillofacial injury ◦ Neck injury
…patient cannot respond? Cyanosis, decerased or no air exchange, facial/cervical crepitus, neck hematoma Simple management maneuvers: ◦ Suction ◦ Chin lift/jaw thrust ◦ Definitive airway: cuffed tube in trachea
Assess for signs of obstruction Confirm correct ET tube position Auscultate in medial axillae Assess oxygenation Assess ventilation (CO 2 detector) Obtain chest X-ray
Protect the cervical spine during airway management!
How do I know ventilation is adequate? ◦ What do I see? ◦ What do I feel? ◦ What do I hear? ◦ What do I measure? ◦ What might I find? ◦ How do I manage the patient?
Respiratory rate and effort Respiratory distress/labored breathing Cyanosis Restlessness/anxiety Chest asymmetry/paradoxical breathing
Crepitance Local tenderness Asymmetric respiratory excursion
Noisy breathing Asymmetric breath sounds Absent breath sounds
Mental status Vital signs Pulse oximetry End-tidal CO 2 ABGs
Tension pneumothorax Pneumothorax Hemopneumothorax Malposiitoned ET tube Neurological deficit Direct neck/chest injury
Establish appropriate airway Administer supplemental oxygen Decompress the chest Reposition the ET tube Provide mechanical ventilation Perform a surgical airway
Mental status evaluation Vital signs Pulse oximetry ABGs
Airway versus ventilation RSI (rapid sequence intubation) – inability to intubate Dislodged/malpositioned ET tube Aspiration Equipment failure
