AHI (apnea-hypopnea index)
What a GLP-1 receptor agonist actually does: which receptors it reaches, how it slows gastric emptying, and the satiety pathway it runs through.
Definition
Apnea-hypopnea index — breathing pauses of ten seconds or more, plus partial reductions with oxygen desaturation, counted per hour of sleep. 5–14 is mild obstructive sleep apnea, 15–29 moderate, 30 or more severe. SURMOUNT-OSA used it as the primary endpoint and tirzepatide 15 mg cut it by about 25 events an hour against placebo.
