Primary central sleep apnea syndrome
MONDO:0024356A central sleep apnea syndrome considered to be idiopathic. Central sleep apnea is caused by improper signaling from the brainstem to the respiratory muscles and is triggered by either hypoventilation or hyperventilation. Clinical signs include snoring, insomnia or hypersomnia, difficulty concentrating, and fatigue. Recurrent episodes of hypoxia/hypoxemia have long-term detrimental effects on cardiovascular health.

New breath test could replace painful lung scopes
Knowledge-focused ENROLLING_BY_INVITATIONThis study aims to see if a simple, non-invasive breathing test can accurately measure the acidity (pH) in the airways, which is often abnormal in lung diseases. Researchers will compare results from this breath test with standard methods in 150 healthy volunteers and people with…
