1. A method of implanting a trans-tracheal sensor comprising:
- forming an opening in a wall of a trachea in a tissue region between a pair of adjacent rings of the wall of the trachea;
slidably inserting a support arm of a sensor assembly into and through the opening in the wall of the trachea to suspend at least one pressure sensitive element on a first end of the support arm within the trachea; and
maintaining a second end of the support arm externally of the wall of the trachea to support the first end of the sensor assembly within a passageway of the trachea for exposure to a respiratory airflow within the trachea.

Abstract
A method of monitoring a physiologic condition includes suspending, via trans-tracheal implantation, a dual pressure sensor for exposure to a bidirectional airflow within the trachea. A respiratory parameter is measured via the dual pressure sensor based on an airflow-induced pressure differential sensed by the dual pressure sensor, and a physiologic condition is determined via the measured respiratory parameter.

13. A method of trans-tracheal sensing comprising:
-
maintaining an opening, via a generally tubular anchor, within a wall of a trachea between a pair of adjacent rings of the wall of the trachea; and removably securing an elongate support arm through the opening, relative to the tubular anchor, to place at least one pressure sensitive element within an airway of the trachea. - View Dependent Claims (14, 15)

16. A method of trans-tracheal sensing:
-
placing, independent of a tracheal cuff, at least one pressure sensing mechanism within an airway of a trachea for exposure to a bidirectional respiratory airflow within the airway of the trachea; and maintaining the wall of the trachea to cause the bidirectional respiratory airflow to pass exclusively through the airway of the trachea. - View Dependent Claims (17, 18, 19, 20)
