CNIM-CS common mistakes

CNIM-CS · Understand the traps and how to avoid them.

Mistake 1

Assuming averaging removes every artifact

The square-root model does not apply to every coherent or nonstationary contaminant.

What to do instead

Check assumptions, reproducibility and artifact timing rather than rely on the trial count alone.

Mistake 2

Trying to recover clipping by rescaling a display

Presentation changes cannot restore information lost during acquisition.

What to do instead

Investigate the acquisition problem and document the limitation while preserving original data.

Mistake 3

Changing an implant without authorization

A technical artifact does not justify an independent clinical device change.

What to do instead

Document the issue and consult the responsible clinical and device team.

Mistake 4

Prioritizing a clean recording over an acute event

Patient protection is more important than an uninterrupted dataset.

What to do instead

Follow the clinical safety response and annotate the event when safe.

Mistake 5

Treating a reassuring EMG threshold as a guarantee

Technique, tissue and blockade can influence the measured response.

What to do instead

Use the actual multimodal and surgical assessment rather than one threshold alone.

Mistake 6

Assuming one modality covers every pathway

Sensory and motor signals measure different parts of the system.

What to do instead

Plan and interpret coverage according to the actual structures at risk and limitations.

Mistake 7

Declaring a unique cause from temporal correlation

Surgical, technical and physiological causes can overlap.

What to do instead

Describe the finding and correlation, escalate and coordinate the appropriate differential checks.

Mistake 8

Calling recovered signals proof of no injury

Recovery is useful but does not guarantee every postoperative outcome.

What to do instead

Document the trajectory and arrange the appropriate handover and outcome correlation.

Mistake 9

Changing anesthesia independently to improve a waveform

Clinical anesthesia management belongs to the responsible anesthesia team.

What to do instead

Communicate the monitoring concern and coordinate within the actual professional roles.

Mistake 10

Using one stimulation intensity for every patient

Device, anatomy, maturation and risk conditions differ.

What to do instead

Follow the qualified individualized plan and actual manufacturer instructions rather than a memorized universal setting.

Mistake 11

Waiting for every check before reporting a serious change

Delay can prevent the responsible team from assessing a time-critical event.

What to do instead

Communicate promptly through the agreed pathway while checks proceed in parallel.

Mistake 12

Overwriting the only raw file

The original evidence and processing audit trail can be lost.

What to do instead

Preserve source data and maintain traceable derived outputs and settings.
