Summary

• POCUS has shown to be a fast, effective and safe adjunct to other ETT position confirmatory methods   

• To confirm ETT placement, the technique can be performed dynamically or statically using a high frequency linear probe placed in the transverse plane at the level of the suprasternal notch  

• With endotracheal intubation, the esophagus should be collapsed​.​​ Only​​ one air filled structure should be seen (trachea) and the snowstorm sign can be seen dynamically.  

• With esophageal intubation, the double tract (double trachea sign) will be seen  

• To confirm ETT placement, ultrasound can be used to assess lung sliding, ​and ​cuff placement​.​ ​     ​  

• Ultrasound can be used to identify the location of the cricothyroid membrane​ to facilitate surgical airway management.​
