Not Everyone With High Flow Limitation Feels Bad — Here's How to Find Out If Yours Matters
Two people with the same FL% can feel completely different. Individual sensitivity to flow limitation explains the gap. AirwayLab's symptom self-report helps you find your own correlation.
The Hidden Respiratory Events Your Flow Data Isn't Showing You
Your AHI is normal, your NED looks clean, but your oximetry shows constant arousals. Brief airway obstructions — events too short and too subtle for standard detection — may explain the gap.
Does Flow Limitation Drive Sleepiness? What the Evidence Shows
Your AHI is 2, your arousal index is low, but you're exhausted. A growing body of research shows flow limitation itself may drive daytime sleepiness — independent of arousals.
Arousals Don't Tell the Whole Story: Why Flow Limitation May Matter More
Sleep medicine assumed arousals fragment sleep and cause symptoms. But research from Dr. Avram Gold and others suggests the stress response to flow limitation itself is the primary driver.
Is the Epworth Sleepiness Scale Measuring What You Think?
You scored normal on the ESS but feel terrible. Recent research by Drs. Gold and Stoohs shows the ESS conflates sleepiness and fatigue — and may be screening out the patients who need help most.
Why Your Brain Might Matter More Than Your Airway: Understanding CNS Sensitization in Sleep-Disordered Breathing
Your flow limitation is mild, but your arousals are through the roof. A growing body of research points to central nervous system sensitization — and your AirwayLab data might already be showing it.
Understanding Flow Limitation: What Your PAP Machine Doesn't Tell You
Flow limitation is the subtle breathing restriction your AHI score completely ignores. Learn what it is, why it matters, and how to detect it in your own PAP data.
Beyond AHI: Why Your Sleep Apnea Score Might Be Misleading You
The Apnea-Hypopnea Index has been the gold standard for decades. But a growing body of research shows it misses critical breathing events. Here's what you should be tracking instead.
Your PAP Data Belongs to You: Privacy in Sleep Medicine
Every night, your PAP machine collects intimate health data. Where does it go? Who can see it? And what are your rights? A look at privacy in the age of connected sleep devices.
