19
Q

two types of sleep related fatigue

A

aCUTE AND cHRONIC

20
Q

this is generally only short-term and can be remedied
with a good night’s sleep

A

Acute

21
Q

a longer-term problem, as there is usually a buildup of
sleep deprivation.

A

Chronic

22
Q

is a brief moment sleep (generally between 2-30
seconds)

A

Micro sleep

23
Q

Two common types of fatigue related errors in
maintenance are:

A

Memory failures
Failures to notice defects or problems

24
Q

difficulty detecting defects during inspections, and may be less likely to
notice problems as a result of inattention or poor concentration.

A

Failures to notice defects or problems

25
Q

Fatigued AMTs are more likely to forget to perform routine actions, such as replacing oil caps, and are more susceptible to distraction and resulting memory lapses.

A

Memory failures

26
Q

Fatigue is caused by a combination of two processes—

A

sleep debt

circadian rhythms.

27
Q

Amount of sleep you should be getting versus the amount of sleep you actually get

A

sleep debt

28
Q

Medical conditions that can cause sleep disruption include the following

A

Insomnia

Restless legs syndrome (RLS)

Periodic Limb movements (PLM)

Sleep apnea

29
Q

An inability to get to sleep, or a difficulty staying
asleep.

A

Insomnia

30
Q

A disorder that causes a strong urge to move
your legs.

A

Restless legs syndrome (RLS)

31
Q

This urge to move often occurs with strange
and unpleasant feelings such as creeping,
tingling, or burning.

A

Restless legs syndrome (RLS)

32
Q

Involuntary leg movements while
asleep. The movements often
disrupt sleep and may cause the
person to wake up

A

Periodic limb movements (PLM)

33
Q

A disorder in which breathing pauses or
becomes shallow during sleep

A

Sleep apnea

34
Q

24 hour rhythms in
our body’s physiology, biochemistry and behavior.

A

CIRCADIAN RHYTHMS

35
Q

The period from around 2am–5am when we would normally be asleep

A time when mental functioning is generally at its worst.

increase the odds of errors, particularly absentminded slips and memory lapses.

Even people without a sleep debt find that their work performance is affected by
fatigue during the WOCL, but a sleep debt will intensify the negative effects of the
WOCL.

A

Window of Circadian Low (WOCL),

36
Q

experience a brief period of confusion, poor
memory and grogginess. This effect, which can
last up to 15 minutes

A

SLEEP INERTIA (AKA “SLEEP DRUNKENNESS”)

37
Q

STRATEGIES TO DEAL WITH FATIGUE

A

GET MORE SLEEP!

38
Q

describes a series of organic
chemicals, but only one type, ethyl alcohol or ethanol, is found in drinks intended for human consumption.

A

ALCOHOL

39
Q

is any substance (solid, liquid or gas) that
brings about physical and/or psychological

Q

Depressants

A

Cannabis

Some solvents and inhalants, many of
which are common household products.

Opiates and opioids, including heroin,
morphine, codeine, and methadone

They can make the user feel more awake, alert, or confident. _________- increase heart
rate, body temperature, and blood pressure.

effects include reduced appetite, dilated pupils, talkativeness, agitation, and sleep
disturbance.

A

that aren’t really there, or what they do see may be distorted in
some way
