HeadGear Wrote:Sleepster,(time=1325110042) Wrote:Presentation of data is only for human consumption! By data, we mean something, a measure or event, is recorded, stored away and retrievable. The machine does not have to do that in order to function. Sensors pick up on respiratory changes which then triggers responses from the machine, according to preset treatment algorithms. It is like steering a car, the steering mechanism simply responds to the input changes, (turn of the wheel,) without any intermediate data recording. But, note, even the "dumber" machines record some data, such as blower hours, number of sessions, etc.HeadGear,(time=1325097670) Wrote:The machine does not have to collect and store data in order to respond to respiratory events, etc.Then what does it use to respond to events?

zimlich Wrote:Each brand of machine has it's own algorithm that it uses in order to and how to respond to events. For instance machines don't respond toclear airway events (except perhaps ASV machines) because they're not respirators. The newer machines however are able to detect CA events and record them.

HeadGear Wrote:Sleepster,(time=1325183707) Wrote:Why not? An auto machine does not operate at a fixed pressure. In the presence of CA, it can either do nothing to raise pressure or it can reduce pressure. The APAP has likely been set to operate at a range of pressure, several cm. H2O below titrated level to several cm. above. In presence of CA, the likely result is that average pressure runs below the titrated level.zimlich,(time=1325165320) Wrote:For instance machines don't respond toclear airway events (except perhaps ASV machines) because they're not respirators.That's interesting. I have a BiPAP machine. It increased dramatically the number of clear airway events I experienced. The doctor lowered the pressure and successfully reduced them. This is something that an auto machine would not do?

Just for clarification of terms...
"Clear Airway Event" is often used by Philips-Respironics instead of "Central Apnea Event". CSA = Central Sleep Apnea CA event = can mean Central Apnea event or Clear Airway event. The difference is that Respironics cannot say for certain that an event that occurs while the airway is open is positively a Central Apnea event (so they use the term "Clear Airway" event instead). They appear to be more cautious in labeling something a central event. ResMed labels seems comfortable labeling them as "central apnea events", and they claim their S9 machines are better equipped to tell when a central event occurs.
