How SpO₂ Changes During Reoxygenation After Breath-Holds
This study tests how peripheral oxygen saturation readings from pulse oximeters behave during deliberate breath-holds and rapid reoxygenation in healthy adults.
-
Berobenatide in adults with sleep apnea and obesity who don’t use a PAP machine
This study tests berobenatide versus placebo in adults with moderate-to-severe obstructive sleep apnea and overweight or obesity who are not using PAP therapy.
-
Berobenatide in adults with sleep apnea and obesity using a PAP machine
This study tests berobenatide vs. placebo in adults with moderate to severe obstructive sleep apnea and overweight/obesity who use a PAP device.
-
Daytime versus overnight titration for hypoglossal nerve stimulation
We will test whether a daytime sleep test works as well as an overnight sleep test to fine-tune hypoglossal nerve stimulation for people with moderate to severe obstructive sleep apnea.
-
Registry for patients with obstructive sleep apnea treated with hypoglossal nerve stimulation
This study is collecting information from patients with moderate to severe obstructive sleep apnea who are using a new device called Inspire to see how well it works and how it helps them over five years.
-
Improving breathing in children with orthodontic treatment
This study is testing if certain orthodontic treatments can help children with breathing problems by improving their airway size and making it easier to breathe.
