NEXUS Chest CT
For blunt trauma patients in whom CT chest is being considered. If any criterion is positive, major or minor thoracic injury cannot be excluded by this instrument.
Clinically major thoracic injuries
All thoracic injuries
Use with standard trauma evaluation and resuscitation. A positive criterion does not by itself mandate CT, but it means thoracic injury cannot be ruled out by the NEXUS Chest CT instrument.
