Airway and Red Flags
Airway risk screen
Stridor
Drooling
Muffled voice
Tripod positioning
Respiratory distress
Inability to swallow secretions
Rapid symptom progression hours
Toxic appearance
Suspected epiglottitis or deep neck infection
Angioedema concern
Immediate escalation triggers
If stridor with increased work of breathing, airway team activation
If suspected epiglottitis, avoid agitating exam, controlled airway plan
If impending obstruction, prepare for awake technique and surgical airway backup
Monitoring and Initial Stabilization
Physiologic priorities
Oxygenation targets
SpO2 94-98% if hypoxemia
SpO2 88-92% if chronic hypercapnia risk
Work of breathing trend
Accessory muscle use
Fatigue
Supportive measures
Humidified air
Upright position
NPO if aspiration risk or airway concern
IV access if dehydration or severe symptoms
Key Concepts
Syndrome framing
Acute laryngitis as laryngeal mucosal inflammation with dysphonia
