Airway and Ventilatory Management Chapter 2
Objectives • Ensure adequacy of the airway • Confirm adequacy of ventilation • Define “definitive airway” • Maintain adequate oxygenation in all phases of airway management
Key Questions • 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?
What if… • …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
What if… • …the patient is hoarse? • Possible: • Laryngeal injury • Laryngeal/tracheal burn • Management: Evaluate and perform • Careful endoscopic exam • Careful and gentle intubation • Surgical airway?
What if… • …the patient cannot respond? • GCS score <9 • Obstruction due to: • Tongue • Aspiration • Foreign body • Maxillofacial injury • Neck injury
What if… • …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
After adjunct • Assess for signs of obstruction • Confirm correct ET tube position • Auscultate in medial axillae • Assess oxygenation • Assess ventilation (CO2 detector) • Obtain chest X-ray
Key questions • 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?
What do I see? • Respiratory rate and effort • Respiratory distress/labored breathing • Cyanosis • Restlessness/anxiety • Chest asymmetry/paradoxical breathing
What do I feel? • Crepitance • Local tenderness • Asymmetric respiratory excursion
What do I hear? • Noisy breathing • Asymmetric breath sounds • Absent breath sounds
What do I measure? • Mental status • Vital signs • Pulse oximetry • End-tidal CO2 • ABGs
What might I find? • Tension pneumothorax • Pneumothorax • Hemopneumothorax • Malposiitoned ET tube • Neurological deficit • Direct neck/chest injury
How do I manage the patient? • Establish appropriate airway • Administer supplemental oxygen • Decompress the chest • Reposition the ET tube • Provide mechanical ventilation • Perform a surgical airway
Ventilation adequate? • Mental status evaluation • Vital signs • Pulse oximetry • ABGs
What are the pitfalls? • Airway versus ventilation • RSI (rapid sequence intubation) – inability to intubate • Dislodged/malpositioned ET tube • Aspiration • Equipment failure
Summary • 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?
