Clear Airway (CA) Question

[Reesche]

Hi you guys.... I have been using my ResMed BiPAP for 4 months now.

I am still waking up feeling tired and out of breath. Yet I am getting good numbers.... See attached Screen shots of last night.

DATA:  I look at ResMed's MyAir and my numbers look good.  I just went through a Mask Change.. From ResMed F30i to Fisher & Paykel "Evora" and it eliminated a bunch of the mask leaks.  However, viewing my data in Oscar, it shows less obstructive Apneas but the Clear Air Way (CA) Apnea where the airway is open is still pretty high.  

Talked to the Respiratory Therapist the other day and she said my "Central Apneas" are still high.  Is the graph in Oscar... Clear Air Way (CA) Apnea where the airway is open the same as Central Apneas in Oscar?  They use a different application on their end.

Thank you, looking forward to your reply.

My Screen shot of ResMed's MyAir did not go through..... Here it is.

Looks to me like a form of positional apnea. The key is the clusters of events. Likely this is you tucking your chin. Try a single pillow or a flatter, less firm pillow to keep your head and neck straighter, thee are more aggressive solutions if needed.

The clusters of CA events could be the same thing, so post a 2-3 minute view so we can see what is going on. Please use the standard order for your charts. Note that the AHI chart is basicly worthless for us to see what is going on, we see it in the events chart

View/reset graphs/ standard from the menu take the screenshot with F12 windos, or FN+F12 on a Mac as that does some temp formating. Basicly dropping the calandar and pie chart so we can see more critical data

 Is the graph in Oscar... Clear Air Way (CA) Apnea where the airway is open the same as Central Apneas in Oscar?  

First, let's be clear, there is no Clear Airway graph in OSCAR. Clear airway events are shown as hash marks on the Events Flags graphic. There is no similar mark for Central events. 

That said, central apnea is a diagnosis,  while Clear Airway is a clinical sign (in much the same manner as elevated pulse rate is a sign, but it does not necessarily mean that the diagnosis is an infection.)

CPAP-APAP therapy can do little to treat an actual central apnea condition. (Actual central apnea is best accommodated by a ventilator - but that is not a treatment)

So, if your medical professional is serious that you are afflicted with central apnea, you should press for a exam that will identify and address the underlying cause.

In general you can assume that CA events are central, but verify first. There are often tells in the Flow rate chart that can be used to prove that they are infact not central. Without question they are not obstructive events, but often are simply the pap user holding their breath while tossing. This holds true for any form of pap machine.

The ASV, the only pap machine that is specifically designed to treat mixed/complex/ idieopathic central apnea doesn't even have a mechanism to detect central apnea.

Again, last nights data.  Not sure what you needed for a screen shot so take a look at these.

Reesche - To take a screenshot in OSCAR, please use the F12 key for a Windows or Linux system, and Fn+F12 key combination for a Mac. The links in my signature have more detailed instructions.
