1. Berlin Questionnaire: series of questons designed to demonstrate the likelihood of palient
having sleep apnea.
2. Hypoventilation: Insuflcient breathing results in increased levels of CO2 and decreased
levels of 02 the blood.
3. High Frequency Filter (HFF): A tool or device on a polysomnograph which sets a
Iimitation to the high frequency signals that allowed to pass through the amplifier.
4. Histogram: a display of sleep stages achieved throughout the sleep period.
5. Nasion: anatomical landmark on the top or bridge of the nose where the forehead and nose
meet. This landmark is used in the International 10/20 System of Electrode Placement to locate
electrode sites.
6. Hyperventilation: A state of excessively fast breathing, resulting in decreased C02 levels
and increased 02 levels in the blood.
7. Sa02: The amount of oxygen in the biood as read by an arterial biood gas.
8. Нypоxia: The state low oxygen levels in the blood.
9. Нурохemia: The state of having habitually low oxygen levels the blood.
10. Hypercapnea: Excess levels of carbon dioxide (CO2) in the blood.
11. Hypnagogic Foot Tremor (HFT): A sleep disorder characterized by rhythmic leg
or foot movements at sleep onset.
12. Impedance: Resistance to the flow of electricity. In polysomnograph, EEG electrode
impedances should be kept below 5000 Ohms.
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 impulses
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
environment.
19. Pneumatic Respiration Transducer: device for detecting A respiratory ettort
that uses cutt and bladder.
20. Major Body Movement: An epoch in which the patient's body movements obscure

21. Calibration: A process of testing and adjusting diagnostic equipment in response 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. ЕРАР: Expiratory positive airway Pressure. Positive Airway Pressure during the exhalation
or expiratory phase of respiration. EPAP and IPAP are identical during CPAP and dissimilar during Bi-
Level PAP.
26. Нyросаpnea: Having too little carbon dioxide in the blood.
27. Ерoch: In polysomnography, a page of the sleep study recording. The paper speed in is
standard polysomnog-raphy 10mm/sec, which produces 30-second page.
28. Нурopnea: 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 resis-tance.
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.

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 ditterent parts of the brain.
