Module 0.5 Flashcards
identify the abbreviations for each ND procedure (including where encephalo in the abbreviation EEG comes from),
Electroencephalogram (EEG)- Electro means electric, encephalo is Greek for brain and gram (or graph) means to record.
Ambulatory EEG,
Electromyography (EMG)- Electro means electric, myo means muscle and graphy means to record
Nerve conduction study or velocity (NCS or NCV)
EVOKED POTENITALS OR RESPONSES:
Visual evoked potential or response (VEP or VER)
Brainstem auditory evoked potential or response (BAER, BAEP, AER or AEP)
Somatosensory evoked potential or response (SSEP or SSER)
Polysomnograph (PSG)- Also called sleep studies. Poly means many, somno is Latin
for sleep and graph means to record
Intraoperative monitoring (IOM) / d surgical monitoring and OR (operating room)
The Long Term Monitoring Unit (LTMU)
state the difference between a symptom and a disorder,
Symptoms that patients complain of for a doctor to order an EEG include:
headaches, dizziness, blackouts, confusion, slurred speech, and or numbness and tingling
of an extremity (arm or leg)
Disorders that can be diagnosed with an EEG include
strokes and seizures. In fact, seizures are the number one reason we perform EEGs
because it is the only test that can diagnose seizures
discuss what symptoms and disorders will be encountered with each ND procedure,
Electromyography (EMG):
Symptoms: that patients may complain of for a doctor to order an EMG include:
pain, numbness, tingling, burning or loss of strength in an extremity (arm or leg) / Disorders that can be diagnosed with an EMG include polyneuropathy, radiculopathy,
Gullian Barre and carpal tunnel syndrome
Nerve conduction study or velocity (NCS or NCV) same as EMG
Visual evoked potential or response (VEP or VER):
Symptoms: that a patient may complain of for a
doctor to order a VEP are blurred vision, double vision, loss of vision/ Disorders: that can be diagnosed with a VEP include multiple sclerosis and optic neuritis
Brainstem auditory evoked potential or response (BAER, BAEP, AER or AEP)
symptoms: Symptoms that a patient may
complain of for a doctor to order a BAER are loss of hearing, dizziness, ringing or
buzzing sounds in the ear/ Disorders that can be diagnosed with a BAER include
multiple sclerosis and tumors. BAERs can also determine the type and amount of
hearing loss
discuss what symptoms and disorders will be encountered with each ND procedure, After Baer
Somatosensory evoked potential or response (SSEP or SSER:
Symptoms: that a patient may complain of for a doctor to order an SSEP include numbness, tingling or weakness of an extremity (arm/leg). Disorders: that can be
diagnosed with an SSEP include multiple sclerosis, tumors and ALS/Lou Garrig’s
disease. SSEPs can evaluate damage to the spinal cord and the brainstem.
Polysomnograph (PSG):
Symptoms: that a patient may complain of for a doctor to order a PSG include daytime sleepiness, the patients might stop breathing from time to time during sleep,
sleepwalking and falling asleep at the wheel/ Disorders that can be diagnosed with a
PSG include sleep apnea, restless leg syndrome, night terrors and narcolepsy. Sleep
apnea is the number one reason we perform sleep studies.
discuss what each ND procedure records (for EEG, know the proper name of the cells it records), state how long each procedure takes, what the preparation is and who performs each procedure (doctor or tech),
Electroencephalogram (EEG)
neuron cells, It takes 1 to 1½ hours to perform, tech does it.
Electromyography (EMG)
a nerve or muscle, It takes the, doctor about 15 minutes.
Nerve conduction study or velocity (NCS or NCV)
nerve damage, A technologist records it.
discuss what each ND procedure records (for EEG, know the proper name of the cells it records), state how long each procedure takes, what the preparation is and who performs each procedure (doctor or tech), AFTER NCS
Visual evoked potential or response (VEP or VER)
- A technologist records it, t 30 to 45 minutes to perform, optic nerve pathway
Brainstem auditory evoked potential or response (BAER, BAEP)
A technologist records it, auditory nerve pathway, It takes about 30 minutes to perform.
Somatosensory evoked potential (SSEP or SSER)
A technologist records it, 1-2 hour, somatosensory pathway.
Polysomnograph (PSG): . It takes from 8 to 10 hours
Intraoperative monitoring (IOM)
Nerves, doctors and techs
discuss the type of stimuli used for each type of EP,
SKIP
discuss the variety encountered with EEGs
a) age (premies, toddlers, teenagers, adults, elderly)
b) type (routine, portable, awake & sleep, electrical cerebral silence (ECS) and NPs, c) state of mind (alert, groggy, confused, combative and comatose)
SKIP
list reasons why procedures may not be done in the ND lab (portables)
A portable EEG is done when the patient is too
sick to come to the neurodiagnostic department
name things that are monitored by an ND tech during surgery.
seizures…….
