Central Sleep Apnea and Sleep Related Hypoventilation/Hypoxemic Syndromes
Central sleep apnea (CSA) and sleep related hypoventilation/hypoxemic syndromes are sleep related respiratory conditions.
CSA occurs when you repeatedly stop breathing during sleep because your brain does not cue your body to breathe. This differs fromobstructive sleep apnea since in central sleep apnea, there is no breathing effort because there is no drive to breathe. In its primary form, CSA is the result of instability of the breathing control system as the individual transitions from wakefulness to sleep.
Sleep related hypoventilation/hypoxemic syndromes may be the result of a decreased response to low oxygen or high carbon dioxide during wakefulness and sleep and are characterized by frequent episodes of shallow breathing lasting longer than 10 seconds during sleep.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
