- ANSWER
when applying the electrodes for the ECG, one should be placed under the right clavicle and the

for the most accurate detection of airflow and scoring of respiratory events, which airflow
collection methods should be used during a sleep study?
- ANSWER both a and b
continuous monitoring and display of blood oxygen saturation levels is critically important in
sleep studies and the signal averaging time should be?
- ANSWER 3 seconds or less
capnography is more commonly used in pediatric sleep studies and is used to measure what?
- ANSWER carbon dioxide levels
,what is the normal range for co2 levels in adults?
- ANSWER 35-45 mmHg
synchronized video collection during the sleep study should be collected at the standard frame
rate of?
- ANSWER 1 per second.
helps to keep file size low. however, if performing studies where movements are important to
observe, like patients with movement disorders, parasomnia disorder or seizures, then you will
want to collect at a 15-20 frame rate per second.

- ANSWER left leg
physiologic calibrations should be performed before light out and again before light on at the
end of the study. true or false?
- ANSWER true, this validates the signal is working as expected. it also aids in scoring the study
during bio calibrations,asking a patient to close their eyes for 30 seconds helps to verify the
presence of what expected waveform?
- ANSWER alpha
, during bio calibrations, asking a patient to move their eyes left and right helps to verify the
presence of what expected waveform?
- ANSWER rapid eye movements
during bio calibrations, asking a patient to move their left and right legs helps to verify the
presence of what expected waveform?
- ANSWER muscle movement
during bio calibrations, asking a patient to hold their breath for 10 seconds helps to verify the
presence of what expected waveform?
- ANSWER apnea
during bio calibrations if the expected waveform is not observed, the most appropriate next
step would be to do what?
- ANSWER stop bio calibrations for a second and try to correct the issue
the sleep technologist should review the patient's chart and confirm that this very important
document is present?
- ANSWER physician's order
the sleep technologist should log study activity about every 30 min or when anything significant
to the study is observed. which of the following would represent the most appropriate type of
comment so that it is helpful to the scoring technologist and reviewing physician?
- ANSWER patient turned from left to side
use the following info to calculate the total recording time(TRT). lights off at 10:00pm. the first
epoch scored as sleep occurred at 10:30pm.lights on at 6:00am. the total sleep time(TST) was
400 minutes.
