Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Conducting a randomized control trial of oxygen in children with Down syndrome to treat moderate to severe obstructive sleep apnea.

The aim of the study is to conduct a comparison between the 2 methods of oxygen delivery during sleep in 15 children from Cincinnati Children's Hospital and Children's Hospital of Los Angeles. 2 polysomnographies will be performed, one with continuous flow and the second with pulse flow.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cincinnati Children's Hospital received NIH funding to conduct a randomized control trial of oxygen in children with Down syndrome to treat moderate to severe obstructive sleep apnea. Oxygen may be delivered through continuous flow for the duration of the respiratory cycle or pulse flow during inspiration only. Pulse flow oxygen concentrators have been used clinically in adults. However, there is limited experience with this technology in children. The advantages of pulse flow oxygen concentrator are its portability and its ability in providing compliance data.

This is a pilot research study to compare the 2 methods of oxygen delivery during sleep in 15 children from Cincinnati Children's Hospital and Children's Hospital of Los Angeles. 2 polysomnographies will be performed, one with continuous flow and the second with pulse flow. The pilot study is conducted in preparation for a larger project which will include 7 sites aiming at determining the effect of oxygen treatment on the frequency of obstructive apnea, neurocognitive and cardiac outcomes. A separate Institutional Review Board (IRB) protocol of the larger study will be submitted later once approved by the NIH Data and Safety Monitoring Board.

Inogen portable oxygen concentrator unit versus continuous flow (Pilot Study)

The aim of this pilot study is to examine whether clinically important indices during sleep are comparable between oxygen delivery by portable and by continuous flow.

Group Type EXPERIMENTAL

Portable oxygen concentrator Inogen G5 model

Intervention Type DEVICE

The concentrator weighs 4.7 lbs. and has a battery life of 13 hours. It has 6 settings with 1 providing the lowest pulse flow and 6 provides the highest flow. The setting will be increased every 30 minutes by 1 when oxygen nadir is lower than 94% and or obstructive index is ≥ 5 /hour.

Reducing the frequency of obstructive apnea (Main study)

The arm of the main study is still under development

Group Type EXPERIMENTAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age 5-17 years with or without Down Syndrome (DS).
2. Children with obstructive sleep apnea (OSA) and obstructive apnea hypopnea index (OAHI) 5-40 / hour: The rationale for selecting this range of OAHI is that a large number of children with DS with this range of OSA severity are untreated for months to years. It is important to understand the response to oxygen across the spectrum of disease severity. Notably, children with severe disease are left with few options (e.g., tracheostomy).
3. Absence of clinically significant hypoxia defined as oxygen saturation \< 88% for 5 minutes or episodic desaturation to 60% as these levels would otherwise identify children eligible to routinely receive oxygen.

Exclusion Criteria

1. Current CPAP use with documented compliance (\> 4 hrs/ night; \> 70% of nights).
2. Oxygen saturation \< 90% at rest during wakefulness
3. Chronic daytime or nighttime use of supplemental oxygen.
4. Unable to participate in a Polysomnogram (PSG).
5. Enrolled or planning to enroll in another study that may conflict with protocol requirements or confound results in this trial.
