Its not available yet. As soon as it's is, I will post a link. PR still has no info on it's website yet. I suspect that will happen this week.Guest wrote:can someone post the soft copy of the manual please.

Periodic Breathing and Variable Breathing are not one in the same according to Respironics.dsm wrote:Another interesting aspect of the reported data from the new machine (that should help those folk stumbling through what Variable Breathing might have meant on the previous Respironics models. VB is defined as 'erratic' breathing in the Respironics patent an on page 25 of the Auto patent tries to explain how erratic breathing was detected & calculated (My analysis is that the machine compares the 1st half of a breathing cycle with the second & tracks this as apattern looking for 'erratic' patterns - this is different from 'predictatble' patterns such as meant by 'periodic breathing' or PB.
The Variable Breathing title has gone & in its place is Periodic Breathing which is a better understood term.
So above, Respironics tells us that Variable Breathing covers a variety of conditions, including wakefulness. Periodic Breathing may be included in that broad VB statistical metric.While discussing their proprietary statistical measure called Variable Breathing, Respironics wrote: The Auto-CPAP... relies on the ability to trend the steady rhythmic breath patterns associated with certain stages of sleep. When a patient is awake, in REM sleep, or in distress, breathing breathing tends to be more erratic, and the Auto-CPAP trending becomes unstable. It is, therefore, important to interrupt the Auto-CPAP if the patient's breathing becomes too variable...."
Periodic Breathing is not that somewhat ordinary wakefulness variability measured by VB. Similarly, Periodic Breathing is not rather ordinary REM associated variability also measured by the proprietary VB statistic.While discussing the clinical event known as Periodic Breathing, Respironics wrote: Periodic breathing is defined as alternating periods of hyperventilation with waxing/waning tidal volume and periods of central hypopneas or apneas. There are many forms of periodic breathing, one of which is Cheyne-Stokes Respiration (CSR). CSR is characterized by a cyclic pattern of waxing and waning during periods of apnea, and deep, rapid breathing.
But the new Respironics algorithm does: 1) employ Forced Oscillation Technique (FOT) to differentiate an open-airway or central apnea, and 2) track and score the highly patterned waxing and waning of Periodic Breathing, to notify clinicians that yet other SDB issues besides ordinary OSA require attention.
What I am very surprised to read is that Respironics claims to be able to somehow differentiate and score Respiratory Effort Related Arousals (RERAS). They can somehow discern brain arousals from a flow signal?
You know but I sure am getting tired of everything being blamed on the FDA. I can't figure out where all this is comming from or is it a ploy because the FDA is so big we can't figure out who to complain to!! Anyone know where the regulation is that says we can't have Encore Pro. What is it that is so bad for us to have. I learned how to push the buttons way before I learned that you could program your change into Encore Pro!!!Kiralynx wrote:He said that the FDA required them to remove Encore Pro from the patient market
Below is the marketing sheet from page 4 of this thread (kudos to socalmonkey). And to my surprise it clearly describes a pressure wave to differentiate centrals:dsm wrote: I never saw any mention of FOT for the new machine
CpapRRT wrote: Per the user manual:
RERA is defined as an arousal from sleep that follows a 10 second or longer sequence of breaths that are characterized by increasing respiratory effort, but which does not meet criteria for an apnea or hypopnea. Snoring, though usually associated with this condition need not be present. The Rera algorithm monitors for a sequence of breaths that exhibit both a subtle reduction in airflow and progressive flow limitation. If this breath sequence is terminated by a sudden increase in airflow along with the absence of flow limitation, and the even does not meet conditions for an apnea or hypopnea, a RERA is indicated.

Does not specify whether or not it will change pressure to correct them.
