OK Called Phillips Resanonics and asked about central apneas...reporting.
AS they are NOT reading brain waves they cannot accurately report on centrals BUT As the machine will sense a non-breathing event and send a pulse of air into the air pipe and react to this test: If there is back pressure it is a obstruction apnea and react and record it as obstruction and if there is no back pressure it will again push air in and record it as a "Open airway" Event..
So open airways can be reasonable be read as centrals.
You learn something every day.
And had posted it on the other thread...I was considering weather to pull this thread BUT I may learn more with as well:
Like what people think of their ASV.
