AI Overview

IntelliPAP, like other auto-adjusting CPAP (Continuous Positive Airway Pressure) machines, responds to flow limitations, which indicate a narrowing or obstruction in the airway, by increasing the pressure to maintain airflow. This response is intended to counteract the reduced flow and prevent airway collapse.
Here's a more detailed breakdown:
Detection:
IntelliPAP uses algorithms to detect changes in airflow, including flow limitations, which suggest a potential airway obstruction.
Pressure Adjustment:
When flow limitations are detected, the device increases the pressure to try and overcome the obstruction and keep the airway open.
Gradual Increase:
The pressure increase is typically gradual, starting with a small increment and potentially continuing as the flow limitation persists.
Response Sensitivity:
IntelliPAP, like other auto-adjusting CPAP machines, can have varying sensitivities to flow limitations. Some devices might respond more aggressively or slowly to these events, and this can depend on the specific device algorithm and settings.
Limited Response at Higher Pressures:
The response to flow limitations might be reduced when the pressure is already high.
Return to Initial Pressure:
Once the normal breathing pattern resumes, the IntelliPAP device will gradually decrease the pressure back to the initial therapy pressure.

Flow Limitation. Both the SleepStyle 200 and S8 units showed a rapid response to the flow-limitation breathing pattern (Figure 2).

however, some of my flowers seem to be limited. or at least not in bloom yet.

Do you have any more questions?

Can the use of BiPAP solve RERA and Flower Limitation?

How are positive pressure ventilators currently used to handle RERA and Flower Limitation events?

1) CPAPs and APAPs are not ventilators. Whether one considers a bilevel PAP machines like a Resmed VAuto or a PR BiPAP a ventilator or not is a slightly different question, but these bilevels do NOT have the ability to trigger an inhalation in a person using the machine. Machines like bilevel ST and ASV machines can be set to attempt to trigger inhalations, and may be considered forms of non-invasive ventilation, but they are also not used to treat plain old ordinary sleep apnea and RERAs or flow limitations.

2) Auto adjusting PAP machines will typically raise the pressure when their algorithms detect changes in the flow rate that indicate a RERA may have occurred or that the inhalations have characteristics of flow limitations. (Flower limitation must be a typo.) How big of a pressure increase will be triggered depends on a whole bunch of things: The machine's proprietary algorithm; how many RERAs are scored in a short period of time; how distorted the inhalations actually are and whether the distortion gets any better with a slight pressure increase; and whether the RERAs/flow limitations are being recorded in the presence of snoring and/or OAs and Hs. A fixed pressure machine (ordinary CPAP or a fixed pressure bilevel) probably won't even bother flagging breathing passages that might indicate a RERA or flow limitation has occurred.

3) In general: You want the minimun pressure setting on an APAP (or auto adjusting bilevel) to be set high enough to prevent most obstructive things from happening during most of the night. In other words, if you are using an APAP and you see a lot of RERAs or flow limitations in the data and you have reason to believe that the flow limitations are actually disturbing your sleep, then it's worth bumping up the minimum pressure to around the median pressure level recorded over several nights data. (Some people would argue to just bump it up to the 90% or 95% pressure setting, but that can lead to aerophagia problems and/or potential problems with CAs in some people.)

Can the use of BiPAP solve RERA and Flower Limitation?

Whether the additional pressure support available on a bilevel (PR BiPAP Auto or Resmed VAuto) will do a better job of addressing problems with RERAs and flow limitations than an APAP is a murky question. On a Resmed VAuto, when flow limitations and/or RERAs are detected, both the EPAP and IPAP will be increased by the same amount. On a PR BiPAP Auto? only the IPAP will increase when flow limitations or RERAs are detected. So it's not at all clear to me if the fact that PS (i.e. IPAP-EPAP) can be set to more than 3 on a bilevel machine might help with attempting to reduce the number of RERAs and the amount of flow limitation being recorded by the machine.
