Nox T3 Quiz
1. If the subject has a Dobhoff tube, what should be done about the nasal cannula for the Nox T3 sleep apnea test?
a) the participant is ineligible for Sleep SMART; exclude or withdraw the subject
b) wait to perform the sleep apnea test until the Dobhoff has been removed
c) try to place the nasal cannula of the Nox T3 device at the nose simultaneously. If this is not possible, omit the nasal cannula and run the sleep apnea test without it.
d) pull the Dobhoff tube out during the Nox T3 night
2. When should a report from the Nox T3 sleep apnea test be provided to subjects and the clinical team?
a) immediately if it shows severe sleep apnea
b) when the subject’s participation in Sleep SMART is over
c) only if the study was technically inadequate
d) anytime the subject asks for it
3. Can an alternative sleep apnea test device or previous polysomnography result be used to determine obstructive sleep apnea eligibility for Sleep SMART?
4. What type of sleep apnea is required for continuation to the aCPAP run-in night?
a) obstructive sleep apnea with an apnea-hypopnea index (AHI) ≥ 10 and with central apnea index < 50% of the total AHI.
b) central sleep apnea with an AHI≥10
c) obstructive sleep apnea with an AHI between 10-100
d) an AHI ≥10
5. Under what circumstances may a Nox T3 sleep apnea test be repeated? Choose all that apply.
a) if the initial test fails due to technical problems (e.g. batteries were not changed and died)
b) OSA was not identified and the subject had O2 supplementation via nasal cannula during the test
c) the subject denied sleeping at least 4 hours during the test period and the test did not show sleep apnea
d) there were no technical or other issues, but the study showed no significant sleep apnea
e) the study showed significant central sleep apnea
