Sensor on non-sealing portion of tracheal tube cuff

A tracheal tube, comprising:

• a tubular body having an open distal end for ventilating a patient;
• a sealing cuff disposed around the tubular body and configured to be inflated to seal the cuff against a wall of a patient trachea;
• and
• a deployment cuff disposed around the tubular body and configured to be inflated to deploy a sensor proximate to the wall of the patient trachea, wherein the sensor is adapted to measure a level of a blood gas and/or a blood analyte in the patient's trachea.

A tracheal tube, comprising:

• a tubular body comprising an open distal end for ventilating a patient;
• a cuff disposed around the tubular body, having a sealing portion and a non-sealing portion, and being configured to be inflated to seal the sealing portion of the cuff against a wall of the patient trachea;
• a sensor disposed on a non-sealing portion of the cuff and adapted to measure a level of a blood gas and/or a blood analyte;
• and
• a lumen extending along the tubular body between a location on the tracheal tube positioned outside the patient when in use to a location on the non-sealing portion of the cuff positioned inside the patient when in use, and terminating near the sensor, wherein one or more conductors are disposed in the lumen and coupled to the sensor.
