Why One Sleep Study May Not Tell the Whole Story: Night-to-Night Variability, AHI Definitions, and OSA Reclassification

By MedXY 06/19/2026

A recent Chest study shows that PSG metrics vary unevenly across nights, and AHI scored with 4% desaturation is less stable than AHI 3%/arousal. Hypoxic burden was more reproducible and may better reflect true OSA severity.

In-Lab vs. At-Home Sleep Studies: Determining Minimum Recording Time and the Role of Positional Sleep Apnea

By MedXY 03/23/2026

This study compares in-lab and home sleep tests, revealing that in-lab polysomnography requires at least 6 hours of recording for accuracy, while home tests need only 3 hours, particularly due to the variables introduced by positional obstructive sleep apnea.
