Why?--Time of snore coincides with OA time, but not time of flow limitation. - 2SleepBetta - 05-13-2018 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. RE: Why?--Time of snore coincides with OA time, but not time of flow limitation. - Walla Walla - 05-13-2018 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. |
