AASM Sleep Tech Practice Questions
& correct answers passed
Review the study and label bad data where the pulse oximeter failed - correct answer ✔✔While
reviewing the scoring report, the tech noticed that the lowest SpO2 is listed at 0%. What should
the tech do next?
1. Do nothing as the report is accurate
2. Review the study and label bad data where the pulse oximeter failed
3. Reschedule the patient for a repeat study because of corrupted data
4. check the pulse oximeter before attempting to generate the report again

✔✔During a multiple sleep latency test, how is sleep onset defined?
1. Three or more epochs of stage N1 or a single epoch of the other sleep stages
2. When spindles are seen
3. The first 30-second epoch in which there is more than 15 seconds of cumulative sleep
4. The first 30-second epoch in which alpha begins to subside
In the preauricular behind the ear - correct answer ✔✔Where are the reference electrodes M1
and M2 placed on the head?
1. On the earlobes
2. In the preauricular behind the ear
3. On either side of the Cz electrode placement
4. Both "on the earlobes" and "in the preauricular area behind the ear"
,Biocalibrations are done at the beginning of the study only - correct answer ✔✔True statements
about the process of biocalibrations include all of the following EXCEPT:
1. The tech notes should reflect the movements made by the patient
2. The patient should be supine and still throughout biocalibrations
3. Biocalibrations are done at the beginning of the study only
4. Nasal and oral breathing are done on the NPSGs only
Nasal pillow masks - correct answer ✔✔Patients who suffer from frequent sinus infections
should be advised not to wear which of the following masks?
1. Nasal masks
2. All of these answer choices
3. Full face masks

for IPAP and EPAP settings during a BIPAP titration?
1. 6-10cm apart
2. 2-8cm apart
3. 4-6cm apart
4. 4-10cm apart
Run the study according to the physicians orders without verification - correct answer ✔✔The
physician's orders indicate the patient is in the lab for a CPAP titration study; however, the
patient insists he has never had a sleep study before. All of the following solutions would be
acceptable to resolve this situation EXCEPT:
1. Attempt to contact the ordering physician, and verify the medical intent
2. Call a member of the lab management team
3. Run the study according to the physician's orders without verification
,4. Look through the patients chart for evidence of a previous study
Remain supine for the entire study - correct answer ✔✔While in the sleep lab, a patient has to
do all the following EXCEPT:
1. Have PSG equipment attached to the body
2. Sign a consent form
3. Remain supine for the entire study
4. Remain connected to equipment for at least 6 hours
All of these answer choices - correct answer ✔✔An artifact that results in salt bridges is most
likely caused by
1. Prepping too large of an area
2. Allowing tape or gauze from different locations to make contact
3. All of these answer choices
4. Incorrect meansuring
Reduced sleep latency - correct answer ✔✔Consuming alcoholic beverages before a sleep study
is likely to have which effect on the patients sleep architecture?
1. Less waking after sleep onset
2. Reduced sleep latency
3. Decreased amount of slow wave sleep
4. Increased REM sleep
Cz - correct answer ✔✔Which electrode site is found halfway between the inion and the
nasion?
1. P4
2. Fz
, 3. Cz
4. Pz
Less than or equal to 10kΩ - correct answer ✔✔Which impedance level is considered
acceptable for EMG channels, such as limbs or chin?
1. Greater than 15kΩ
2. Less than or equal to 10kΩ
3. Less than or equal to 5kΩ
4. Less than or equal to 25kΩ

face mask or oral mask during a CPAP study?
1. The patient is claustrophobic
2. The patient has a deviated septum
3. The patient feels congested
4. The patient is a mouth breather
All of these answer choices are true - correct answer ✔✔Why is precise measurement of the
head important of a PSG?
1. Artifacts can be caused by improper placement of electrodes
2. Is is important for the identification of sleep onset and specific sleep stages
3. Observation of important waveforms require precise electrode placement
4. All of these answer choices are true

that a patient is entering stage N1 sleep from the wake stage EXCEPT:
1. The eyes mirror the EEG frequencies
