Thanks for your experiences.
Right now I am working backwards from the APAP settings with the machine set in CPAP mode. I see that some of reported CA events are not true CA events, but I do find that they do nonetheless contribute to unproductive sleep. I seem to do better at a lower constant pressure. Still trying to find the bottom but I think I'm on the right track. I think I may have to accept the occasional spike in AHI due to the random nature of some CA events. It seems I have to find that sweet goldilock's setting where I average an acceptable AHI. Thanks again for your input.
I would accept a higher number of obstructive apneas if it reduced my central ones and lowered my totals. It seems like solving the obstructive issues is simpler since it is a question of pressure only. Complex apneas could have multiple causes. Causes that might not show up in a titration study.
I have had a number of sleep studies and I find that doctors just use the data to suggest pressure settings. They don't make any money looking at your data. I need a doctor who treats the patient and not the data.
I would be interested in where you read that. I highly suspect that it is accurate since by definition an apnea must last 10 seconds. Can this happen to many people? Probably about none. Please use this forum more wisely.
Thanks for the input.
I use a Dreamwear full face make and I suspect that occasionally I can drop my jaw below its' bottom. Would I not see a drop in mask pressure associated with the central apneas if this were the case?
I find your suggestion regarding circulation interesting. I am on a very low dosage of Metropolol (25mg) which I believe lowers my heart rate and my diastolic pressure has also been on the low side recently. I would gladly trade a slight increase in my blood pressure for improved sleep.
Looks like I have further investigation to do.
After being on CPAP for many years, suddenly my AHI numbers are varying quite a bit.
After struggling resolve it with APAP I finally found some success reverting to straight CPAP. SleepyHead was showing that my obstructive apneas were quite low, below 1.0. The majority of the apneas were reported as central apneas.
For a a few weeks total apneas were in the 5.0 range which I find acceptable, but then they would steadily creep up to the 10.0 range again. A slight pressure adjustment would return the number back down, only to see it creep up again. I have been having pain from some herniated discs in my back and I can see that the Sleepyhead data shows a spike before some tags of a central apnea. I am attributing these to back pain restlessness.
I am scheduled for a diagnostic shot in my lower back to isolate effected nerve for future treatment.
I am curious if anyone has had varying AHI's due to other unrelated health issues.
Though not recommended because it will relax muscles and may increase apneas, I have used it many times and the Ativan has not caused me any problems. Take it for your anxiety, which at this point seems to be the more pressing problem. There are good medications to treat panic and anxiety today, make an appointment to see a doctor.
Sleep apnea in itself is not life threatening, although its' untreated longterm effects can be. Have a sleep study done and find a therapy that works for you. Good Luck. Relax
Find a new doctor.
I am using a Resmed A10 and I notice that the CA events are the majority of my AHI number every night. These are pushing the AHI almost consistantly well above 5. My OA episodes are resolved well below my max setting 0f 5-15. I have had 2 sleep studies in the last year and neither have observed any complex or central sleep apneas.
I have had zero mask leaks on my F20 full face mask on most nights. The few times I have been below 5 (3.2 and 4.1) I have noticed a tremendous difference in increased energy during the day. The little research I have done with the sleeplyhead software seem to indicate that these CA events might be a yawn. Is is possible I am yawning because my oxygen levels have dropped? How do I find this out and has anyone had a similar problem and could you graciously point me in the right direction?
I know it is good when it works, but lately my therapy is falling a little short of the desired results.
