Why?--Time of snore coincides with OA time, but not time of flow limitation.

Why?--Time of snore coincides with OA time, but not time of flow limitation.
Often, if not always, I see coincidence of the time of a snore with time of an obstructive apnea, but no concurrent indication of a flow limitation. Why is that?

What are the "mechanics" that explain the flow difference between a snore and a flow limitation? This question arises as I view Sleepy Head graphics.
I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.  (Disclaimer use permitted by sheepless)

RE: Why?--Time of snore coincides with OA time, but not time of flow limitation.
On a Resmed machine a OA/H event will be at least a 50% reduction of flow for at least 10 seconds. If it's less than either it will show up as a flow limitation. The difference between the flow limitation and snore is how it's recorded in the flow chart. The flow limitation will show reduced flow on the chart where a snore will show more of a ragged disruption to the flow pattern. If you go to the link Beginners Guide to sleepyhead below it shows chart examples.
