1. A system for performing bronchial denervation, the system comprising:
an electromyography system having a cryoablation device with at least two recording electrodes,
wherein the electromyography system is configured to:
calculate a difference between a first electromyogram signal received from a first recording electrode and a second electromyogram signal received from a second recording electrode to generate a recorded electromyogram; and
compare the recorded electromyogram to a reference electromyogram.
