One tract: normal airway and correct tracheal intubation
Two tract: should consider esophageal intubation
For airway management and ventilation confirmation: use curvilinear probe
For airway evaluation and possible cricothyroid membrane: use linear probe
At least 3 important structures to be identified while you scanning the neck:
Trachea
Esophagus
Cricothyroid membrane
Location of your probe: transverse scan on the suprasternal notch
