Claim Text:
1. A method comprising: measuring a tracheal pressure of a patient's trachea with a pressure transducer in fluid communication with a pressure monitoring lumen, wherein the pressure monitoring lumen is associated with a tracheal tube; receiving information related to a respiratory gas pressure over a breathing cycle of a patient; determining a baseline pressure associated with a minimum pressure point over the course of the breathing cycle of the patient; delivering a purging fluid as a bolus of purging fluid timed to coincide with the minimum pressure point over the course of the breathing cycle of the patient through the pressure monitoring lumen at a purging pressure greater than the respiratory gas pressure; and determining a corrected tracheal pressure of the patient's trachea that accounts for the bolus of purging fluid based at least in part on the baseline pressure, wherein determining the corrected tracheal pressure comprises substituting the measured pressure during the bolus delivery with the baseline pressure.
