"Identification of the tip of the ETT and awareness of secondary signs of the endobronchial intubation is pivotal in making the diagnosis."
"Ideally, ETT tip position should be below the interclavicular line and approximately 2 cm above the carina. This allows for tube tip movement when the neck is moved 2: when the chin is depressed, the tube tip will move downwards and when the chin is lifted, the tube tip will move upwards."
"may demonstrate dilation of tracheal mucosal-air interface with posterior reverberation artifacts as the ETT cuff is inflated"
