1. A tracheal tube, comprising:
- a tubular body having a recess disposed therein and an open distal end for ventilating a patient;
a cuff disposed around the tubular body above the open distal end and configured to be inflated to seal the cuff against a wall of a trachea; and
a sensor coupled to a membrane that is selectively permeable to a blood gas and/or blood analyte, wherein the sensor is configured to measure a level of the blood gas and/or the blood analyte in the trachea, and wherein the recess receives the sensor during intubation and extubation.

Abstract
Various embodiments of an tracheal tube having a sensor coupled to a selectively permeable membrane are provided. In some embodiments, the membrane may be permeable to one or more blood gases and/or blood analytes. Certain embodiments of the endotracheal tube may be capable of deploying the sensor during intubation to sense one or more indicators of blood flow characteristics, such as a level of blood gases and/or blood analytes, in the respiratory tract. Embodiments of the present invention may include positioning of the sensor in a variety of suitable positions with respect to the permeable membrane, such as mounting the sensor to the underside of an inflatable permeable membrane.
