1. An endotracheal tube comprising:
- a conduit adapted to transfer gas to or from a patient'"'"'s lungs;
an inflatable balloon cuff disposed on the conduit, the inflatable balloon cuff having a proximal end, a distal end, and a body extending from the proximal end to the distal end, wherein the inflatable balloon cuff is adapted to form a seal against a patient'"'"'s tracheal walls; and
at least one carbon dioxide sensing component disposed on the proximal end of the inflatable balloon cuff that does not form part of the seal, wherein the carbon dioxide sensing component is configured to send a signal that correlates to a level of secretions on the cuff.

Abstract
An airway device is provided that may track the flow of respiratory gases through the device with sensing elements at a plurality of locations along the gas flow path of the device. Such a device may be useful for assessing a variety of clinical states, for adjusting patient ventilator settings, or for determining whether or not an airway device has been properly inserted into a patient airway.

12. A system comprising:
-
a conduit adapted to transfer gas to or from a patient'"'"'s lungs; an inflatable balloon cuff disposed on the conduit, the inflatable balloon cuff having a proximal end, a distal end, and a body extending from the proximal end to the distal end wherein the inflatable balloon cuff is adapted to form a seal against a patient'"'"'s tracheal walls; and at least one carbon dioxide sensing component disposed on the proximal end of the inflatable balloon cuff that does not contact the tracheal walls when the inflatable balloon cuff is inflated, wherein the at least one carbon dioxide sensing component is configured to send a signal that correlates to a level of secretions on the cuff; and a monitor adapted to be operatively coupled to the at least one carbon dioxide sensing component. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method comprising:
-
providing a conduit adapted to transfer a gas to or from a patient; providing an inflatable balloon cuff disposed on the conduit, the inflatable balloon cuff having a proximal end, a distal end, and a body extending from the proximal end to the distal end wherein the inflatable balloon cuff is adapted to form a seal against a patient'"'"'s tracheal walls; and providing at least one carbon dioxide sensing component disposed on a proximal portion of the inflatable balloon cuff that does not form part of the seal, wherein the carbon dioxide sensing component is configured to send a signal that correlates to a level of secretions on the cuff. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method comprising:
-
receiving a signal from at least one carbon dioxide sensing component disposed on an inflatable balloon cuff having a proximal end, a distal end, and a body extending from the proximal end to the distal end and wherein the inflatable balloon cuff is operatively connected to an endotracheal tube, and wherein the carbon dioxide sensing component is disposed on the proximal end of the inflatable balloon cuff not in contact with a patient'"'"'s tracheal walls; and correlating the signal to a level of secretions on the cuff. - View Dependent Claims (35, 36, 37, 38)

39. A method comprising:
-
receiving a first signal from a first carbon dioxide sensing component disposed on an endotracheal tube; receiving a second signal from a second carbon dioxide sensing component disposed on an inflatable balloon cuff associated with the endotracheal tube, wherein the inflatable balloon cuff comprises a proximal end, a distal end, and a body extending from the proximal end to the distal end and wherein the second carbon dioxide sensing component is disposed on the proximal end of the inflatable balloon cuff; and correlating a difference between the first signal and the second signal to a level of secretions on a surface of the endotracheal tube. - View Dependent Claims (40, 41, 42)
