There is disclosed a tracheal tube for insertion into the trachea of a patient. The tracheal tube includes a tube portion having a distal end, and a signal source associated with the tube portion at a predefined distance from its distal end. The tracheal tube is inserted into the trachea such that the signal source is immediately posterior to the patient's cricothyroid ligament. Methods related to confirming proper placement of the tracheal tube by detecting the signal source immediately posterior to the patient's cricothyroid ligament are also disclosed.
