Browse categories and answer follow-up questions to refine your symptom profile.
Immediate priorities
Stabilization and early threats
Airway protection triggers
GCS < 8
Refractory hypoxemia despite high-flow oxygen
Severe work of breathing
Inability to clear secretions
Breathing targets
SpO2 92% to 96%
PaO2 10.7 to 13.3 kPa (80 to 100 mmHg) when ventilated
Avoid hyperoxia in COPD risk
Circulation priorities
Hemorrhage control and permissive hypotension principles until bleeding controlled
Avoid unnecessary crystalloid boluses in isolated lung injury
Early imaging pathway
Chest X-ray for screening
CT chest when significant mechanism or worsening oxygenation
Immediate complication screen
Pneumothorax
Hemothorax
Flail chest
Major thoracic vascular injury
Cardiac contusion
Aspiration
Key decision points
Escalation triggers
Rapidly increasing oxygen requirement within 6 to 24 hours
Evolving contusion pattern
Occult pneumothorax progression
Hypotension with new hypoxemia
Tension pneumothorax consideration
Massive hemothorax consideration
Hemoptysis with respiratory decline
Tracheobronchial injury consideration
Pulmonary laceration consideration
Fever and purulent secretions after 48 hours
Ventilator-associated pneumonia consideration
Aspiration pneumonia consideration
