To stimulate both PTN asynchronously, what is required?

To stimulate both peripheral nerve trunks asynchronously, it is essential to delay the second stimulator. Asynchronous stimulation implies that the two stimulators activate the nerves at different times rather than at the same moment. This time delay allows for separate neural responses to be recorded, which can help in evaluating the conduction characteristics of each nerve independently.

When you induce a delay in the second stimulator, it ensures that the first response has already been triggered, allowing for clear differentiation of the various neurophysiological signals. This separation in timing is crucial for analyses and interpretations during intraoperative monitoring, where understanding the individual function of each nerve is vital for maintaining patient safety and the integrity of the neurophysiological assessment.

Using longer pulse widths or increasing intensities may not achieve the desired asynchronous result, and simultaneously triggering both stimulators would lead to overlapping responses, complicating the interpretation of the data.
