13. Bioelectric Potentials: Electrical signals that originate from a living source.
14. Histamine: A chemical in the brain responsible for activation of the cortex.
15. Neurotransmitters: Chemicals in the brain that allow for the exchange of im-
pulses from one neuron to the next.
16. Sampling Rate: The designated number bits recorded per second in a channel.
17. Pittsburgh Sleep Quality Index (PSQI): A series of questions in which the
patient provides a subjective assessment of their own sleep quality.
18. Maintenance of Wakefulness Test (MWT): A sleep study in which the patient
is given several opportunities to remain awake while in a relaxed, darkened environ-
ment.
19. Pneumatic Respiration Transducer: device for detecting A respiratory effort
that uses cuff and bladder.
20. Major Body Movement: An epoch in which the patient's body movements
obscure the tracings to the point that the sleep stage cannot be determined.
21. Calibration: A process of testing and adjusting diagnostic equipment in re-
sponse to varying voltages of known value. This process ensures reliability in
recorded signals.

22. Sleep Log: A diary of an individual's time in bed, estimated total sleep time,
lights out time, lights on time, and daily activities. Sleep logs can help clinicians
determine circadian rhythm disorders and causes of insomnia.
23. Canthus: Either corner of the eye, where the upper and lower eyelids meet. The
outer canthus is used as a landmark for placing EOG electrodes.
24. Sleep Mentation: Thoughts and feelings that take place during sleep.
25. : Expiratory positive airway Pressure. Positive Airway Pressure during the exha-
lation or expiratory phase of respiration. EPAP and IPAP are identical during CPAP
and dissimilar during Bi-Level PAP.
26. y@>A0
pnea: Having too little carbon dioxide in the blood.
27. @och: In polysomnography, a page of the sleep study recording. The paper speed
in is standard polysomnography 10mm/sec, which produces 30-second page.
28. C@
opnea: A decrease in airflow for at least ten seconds caused by a partial
obstruction in the upper airway.
29. Epworth Sleepiness Scale (ESS): An index of sleepiness during the day as
perceived by patients, derived from the answers to 8 questions.
30. V Waves: Sharp negative deflections seen in an EEG channel. V Waves are
characteristic of the latter part of stage N1. V Waves were formerly called Vertex
Waves or Vertex Sharp Waves.
31. Esophageal Balloon: A device inserted into the esophagus to measure small
changes in airway resistance.
32. Volt: A measurement of electrical force.
33. Sleep Related Hallucinations: These are hallucinations either at sleep onset
or upon awakening, often associated with sleep onset REM periods (SOREMP's),
and may be frightening to the patient. These occur the absence of narcolepsy.
34. End Tidal CO2: A reading of carbon dioxide levels in the blood as measured by
expired air.
35. Suprachiasmatic Nucleus: A structure in the brain responsible for the 24-hour
circadian rhythm.
36. Sleep Related Eating Disorder: This disorder includes repeated episodes of
eating and/or drinking during arousals from sleep. This often occurs on a nightly
basis, or several times a night. the patient usually chooses junk foods.
37. Environmental Sleep Disorder: A secondary sleep disorder caused by a sleep
disorder present in a bed partner, poor sleep hygiene, or other factors.
38. Thalamus: A structure in the brain responsible for relaying certain sensory
information from the body to different parts of the brain.
39. Delayed Sleep-Wake Phase Disorder: This is characterized by later sleep time
than expected. Patients with this disorder are usually adolescents or young adults,
and tend to stay up late at night and wake up late the morning.

40. Long Sleeper: This symptom occurs when a person sleeps >10 hours per 24
hours, and is not explainable by another sleep disorder. The requirements change
according to age, since infants need this much sleep normally.
41. Irregular Sleep-Wake Rhythm Disorder: This disorder is characterized by
abnormal sleep and wake times. Although the total sleep time during the 24-hour
period may be normal, the sleep periods may come the form of several naps.
42. Body Mass Index: A calculation of height and weight.
43. Advanced Sleep-Wake Phase Disorder: This is characterized by an earlier
sleep time than expected.Patients with this disorder are usually elderly, and tend
to go to bed early at night and wake up early in the morning.
44. Short Sleeper: This symptom occurs when a person sleeps <5 hours per 24
hours, and is able to maintain normal functionality and wakefulness. This type of
individual does not require the normal amount of sleep.
45. Non-24-Hour Sleep-Wake Rhythm Disorder: This is a circadian rhythm that is
not consistent with the 24- hour clock. The patient's circadian rhythm is often longer
than 24 hours, and does not seem to be related to the light- dark cycle.
46. Bundle Branches: Three branches from the bundle of HIS in the heart that run
along the interventricular septum.
47. Current (I) equals Voltage (V) divided by Resistance (R).
| = V/R: How is electrical current calculated?
48. AC signals can alternate quickly between positive and negative voltages,
while DC signals change slowly and range from 0 - 1V.: What is the difference
between an AC signal and a DC signal?
49. The small, cup-shaped head makes it easy to be placed securely against
the scalp and hold conductive paste. They are also made of a highly conduc-
tive metal, usually gold or silver silver- chloride.: Why are cup electrodes used
in electroencephalography?
50. Snore microphones detect the noise from the snores and can be placed
wherever snoring is heard the loudest, close to the nose or mouth or on the
throat. Snore sensors record vibrations from the snores and are placed on the
throat.: What is the difference between a snore microphone and a snore sensor?
51. One end shines a red light through the finger while the other end detects
that light. Blood that is highly saturated by oxygen is lighter in color, and
allows more light to pass through it.: How does an oximeter estimate the blood
oxygen level?
52. Thermocouples detect the rate of temperature change by using two dis-
similar metals that are sensitive to temperature change. Thermisters use a
wheatstone bridge circuit to amplify the difference in temperature between
