Mimium should be the higher of

4 + EPR (which is 3) = 7 set Min =7
higher as determined by titration (I can see 8 a a real possibility, but try 7 first.
RE: How long is too long?
As bonjour says, the problems are in the settings. You are at 4.0 to 20. with EPR 3. Make your minimum pressure 8.0 and you will do great. I'll predict less than 1.0 AHI. Good luck
RE: How long is too long?
Hello thebestdog, Although, I do not have many obstructive apneas, I do have many central apneas (30 or so in a typical night). A few have a duration longer than 30 s. and some (one or two) may reach 40 sec. As of 10 days ago I have been able to observe simultaneous pulse oximetry data. During a 41 s apnea last night the O2 saturation dropped from 97 to 91% but rapidly recovered to 99% after 3-4 recovery breaths. It seems the drop recorded depends on the strengths of the preceding breaths (as to be expected expected) combined with the length of the apnea itself. If you are concerned I suggest you obtain a recording oximeter - the recent drop the price wrist and ring oximeters makes them much more accessible. My results show that my oxygen saturation is seen to drop only briefly during the apnea events and recovers quickly.
RE: How long is too long?
You're not heavily desaturating, but a 6% drop is likely to disturb your sleep. Are you seeing these centrals steadily (~4/hour) or do they cluster?

Sawinglogz, my response was not meant to hijack the thread. I only meant to respond to the original post which asked us to "Let me know what you're longest obstructive apnea is on a typical night" and no one had answered this request. I also wanted to make the point that the occasional long apnea may not be a problem.

I did. "...
To answer your questions, my longest obstructions or 'clear airway' (deemed by RESMED to be central apneas) on any one night is going to be in the 19 second range..."
RE: How long is too long?
I'm Replying to my own post - that seems a bit odd- I'm not sure how this works but will figure it all out later. For the minute I want to say a big thank you to everyone who has responded, there are some very interesting points and a lot to digest. It has been very helpful and I have discovered a lot in the last few days. At the the minute I am taking note of your suggestions and fiddling with my settings. I hope to reply to everyone individually over the next few days and update you with any changes that may or may not have happened. And I will probably have more questions for you
I'm sure that my pressure is too low but I was just given a machine by my health care provider and nothing else was explained to me. It's autoset so they have assumed that it will just do the business without any interventions on their part.
I am particularly interested in REM specific sleep apnea and have read some academic literature on this subject. I am a postgraduate student studying space science and technology. Although I don't have any medical qualifications I get the gist of what the arguments are re treating or not treating rem specific apnea and I would love to hear from anyone who is knowledgeable on that subject.
RE: How long is too long?
I know this isn't helpful for you personally. But I wanted to respond to your question about how long is too long, because I think it's an important question for all of us.
I go about this question in this manner:
- My sleep "doctor" did not want to diagnose me with sleep apnea (and most certainly didn't want to Rx a CPAP), because it wasn't "severe enough". My question was this: "It is impacting me in every way of my life, and has for several decades. How much more severe does it need to be?" Just because most of the time I hold my breath for an amount of time that is *just under* the arbitrary time alloted for calling something an apnea (thus it doesn't get counted), does that mean my breath-holding is irrelevant? NO!
So my opinion is that any amount of time is too long. And if it's impacting our lives, then lets get it treated!
