Tracheal tube apparatus and methods

A tracheal tube assembly comprising:

• an outer cannula having an outer cannula proximal end and an outer cannula distal end, the outer cannula distal end having outer cannula threads;
• an inner cannula configured to insert into the outer cannula and having an inner cannula proximal end and an inner cannula distal end, the inner cannula distal end having an inner cannula coupler for mating with the outer cannula threads, wherein at least a portion of one or both of the inner cannula and outer cannula are transparent and configured to indicate by a color change that the inner cannula and outer cannula are connected;
• and
• an elbow adapter configured to couple the inner cannula with a mechanical ventilator for providing air to a patient;
• a pressure release valve on the elbow adapter configured to mitigate high airway pressures that may cause disconnections or lung damage;
• a Bayonet Neill-Concelman (BNC) connector configured to secure the elbow adapter to the inner cannula;
• and
• an air flow indicator in communication with the pressure release valve, configured to indicate when the elbow adapter should be replaced.

• an anti-microbial agent on one or more regions of the tracheal tube assembly;
• a suction port for removal of moisture or secretions from the assembly;
• and
• an air flow indicator in communication with the pressure release valve, configured to indicate when the elbow adapter should be replaced.
