1. A system, comprising:
a tracheal tube positioned within an airway of a ventilated patient;
an acoustic sensor coupled to the tracheal tube; and
a monitor communicatively coupled to the acoustic sensor, wherein the monitor comprises a processor, and wherein the processor is configured to:
receive a baseline signal from the acoustic sensor;
receive an updated signal from the acoustic sensor after an adjustment to one or more ventilatory parameters to deliver a gas mixture to the airway through the tracheal tube; and
identify a change in a lung parameter of the ventilated patient caused by the adjustment of the one or more ventilatory parameters, wherein identifying the change is based on the baseline signal and the updated signal.
