Airway Management Decision Tree
Interactive Assessment and Management Algorithm for Emergency Airway Control
Work through the trauma airway decision tree, from initial airway assessment and basic maneuvers through rapid sequence intubation and the surgical airway.
Step 1: Initial Airway Assessment
Rapid evaluation of airway patency and breathing adequacy
Assessment Criteria
- Can the patient speak clearly?
- Is there audible stridor or wheeze?
- Are there signs of respiratory distress?
- Is the patient maintaining oxygen saturation?
Actions to Take
- Look for visible obstruction
- Listen for abnormal sounds
- Feel for air movement
- Check oxygen saturation
Warning Signs
- Complete inability to speak
- Audible stridor
- Cyanosis
- Use of accessory muscles
Step 2: Basic Airway Maneuvers
Non-invasive techniques to establish and maintain airway patency
Assessment Criteria
- Patient is conscious and cooperative
- No suspected cervical spine injury
- Partial airway obstruction only
- Adequate spontaneous breathing effort
Actions to Take
- Head-tilt, chin-lift maneuver
- Jaw-thrust maneuver (if C-spine injury suspected)
- Remove visible foreign objects
- Insert oral or nasal airway
Warning Signs
- Decreasing level of consciousness
- Worsening respiratory distress
- Inability to clear secretions
- Hemodynamic instability
Step 3: Advanced Airway Decision
Determine need for advanced airway intervention
Assessment Criteria
- Failure of basic maneuvers
- Anticipated clinical course
- Need for mechanical ventilation
- Procedural requirements
Actions to Take
- Assess difficult airway predictors
- Prepare backup plan
- Consider awake intubation
- Optimize patient positioning
Warning Signs
- Predicted difficult intubation
- Limited mouth opening
- Neck immobility
- Facial trauma or edema
Step 4: Rapid Sequence Intubation
Pharmacologically assisted endotracheal intubation
Assessment Criteria
- Patient requires immediate airway control
- No contraindications to medications
- Appropriate personnel and equipment available
- Backup airway plan in place
Actions to Take
- Pre-oxygenate with 100% O2
- Administer sedative and paralytic
- Perform direct laryngoscopy
- Confirm tube placement
Warning Signs
- Hemodynamic instability
- Anticipated difficult airway
- Inadequate pre-oxygenation
- Equipment failure
Step 5: Surgical Airway
Emergency surgical access when other methods fail
Assessment Criteria
- Cannot intubate, cannot ventilate scenario
- Massive facial trauma
- Complete upper airway obstruction
- Failed multiple intubation attempts
Actions to Take
- Prepare cricothyrotomy kit
- Identify anatomical landmarks
- Make horizontal incision through cricothyroid membrane
- Insert appropriate sized tube
Warning Signs
- Inability to identify landmarks
- Coagulopathy
- Previous neck surgery
- Pediatric patient < 10 years
Difficult Airway Predictors
Anatomical Factors
- Limited mouth opening (< 3cm)
- Short neck or limited neck extension
- Prominent incisors or overbite
- Receding chin or micrognathia
- High arched palate
Pathological Factors
- Facial trauma or burns
- Neck masses or swelling
- Trismus or jaw fracture
- Laryngeal edema
- Previous difficult intubation
Environmental Factors
- Cervical spine immobilization
- Limited access to patient
- Vomit or blood in airway
- Inadequate lighting
- Time pressure
Critical Airway Management Principles
- • Always have a backup plan - if you can't intubate, you must be able to ventilate
- • Pre-oxygenation is crucial - aim for 3-5 minutes of 100% oxygen
- • Consider awake intubation for predicted difficult airways
- • Don't delay surgical airway in "can't intubate, can't ventilate" scenarios
- • Confirm tube placement with multiple methods (EtCO2, bilateral breath sounds, chest rise)
