According to this:
I'm feel sure that this is also the basis of Resmed's identification.The American Academy of Sleep Medicine (AASM) recommends that hypopneas be identified using a definition that is based on a ≥ 30% decrease in airflow,,,, ]
BUT a decease or reduction has to be measured by comparing, in this case, current airflow versus ..... what?
Is it the airflow of the breath immediately before the current breath, or some baseline value.
If it is some baseline, if so, how is that baseline determined or calculated?
Is it the previous 10 breaths or the breaths over some period of time?
Or something else?
*Understanding this would aid in evaluating a Hypopnea as a "real" or a false positives.
