Aspects of this disclosure describe methods and systems for evaluating phrenic nerve integrity of a patient and a ramp-up pulse string for nerve stimulation. Integrity of a nerve may be assessed and therapy may be slowly introduced to the patient. To determine integrity, a nerve is electrically stimulated and a return signal is evaluated. For example, a time lapse and a band width of the return signal may provide information about nerve damage and a location of the nerve damage. In addition to assessing nerve integrity of a patient, a stimulation burst (e.g., an electrical stimulation) may be delivered as a ramped-up pulse string (e.g., a series of pulses with increasing voltages) to achieve smooth breathing. The voltages of a stimulation burst may be increased based on a target tidal volume for the patient. The stimulation burst may be delivered during an inhalation phase of a breath.
