ECS caused by drug intoxication is not reversible

Answer 1

FALSE -drug intoxication will mimic ECS

Question 2

Children’s brains are more resistant to damage when compared to adults

Answer 2

TRUE

Question 3

At 7 uv/mm a signal of 2 uv can be seen clearly because of differential amplifiers

Answer 3

FALSE

Question 4

High impedances enhance brain waves

Answer 4

FALSE -restricts voltage flow

Question 5

When a patient is hypothermic, it’s a good time to evaluate them for an ECS recording

Answer 5

FALSE- may mimic cerebral death

Question 6

Three main purposes for recording bedside

Answer 6

1) too ill to move
2) need respirator
3) pt. may be attached to too many machines

Question 7

What exactly does the American EEG Society define as ECS

Answer 7

No EEG activity over 2uv when recording from scalp electrode pairs 10 or more cm apart

Question 8

What special ECS information about the pt. should be listed clearly at the beginning of the record?

Answer 8

Vital signs

Question 9

What may mimic cerebral death?

Answer 9

Hypothermia and drug overdose

Question 10

If person has too much muscle artifact during an ECS recording, what do we do about this?

Answer 10

Give anectine or pavulon- performed under direction of physician

Neuromuscular blocking agent

Question 11

ECS can be viewed as a humane measure, why?

Answer 11

• ends suffering
• families relieved of expenses and grief
• beds made available for critical pts.

Question 12

Name two recommendations that may be procedure for ECS recording

Answer 12

• open up a LF of .3Hz

- two electrodes on the back of hands

Question 13

Why do we record for more than 20 minutes?

Answer 13

Up to 20 minutes may occur in low voltage records and therefore at least 30 minutes to make sure you didn’t miss anything

Question 14

What is the most common artifact encountered during a bedside recording?

Answer 14

60Hz (respirator, equipment)
