The average 4% oxygen desaturation index was statistically higher in the nasal high flow therapy group vs oxygen supplementation only control group.
Sleep disturbances caused by the symptoms of COPD are associated with airway constriction heterogeneity, which could be reflective of peripheral airway dysfunction.
The threshold STOP-Bang score for moderate to severe sleep apnea was 6 (which correlated with apnea-hypopnea index of ≥15) and this score had a sensitivity of 63% and a specificity of 69%.
Respiratory polygraphy can accurately diagnose sleep apnea in patients hospitalized with heart failure.
When sleep apnea was not managed with continuous positive airway pressure, the risk for heart failure increased, regardless of age.
Obstructive sleep apenea may increase the amyloid burden in cognitively normal older patients.
