Thank you for your input Sleeptech. Makes me feel a little more reassured.
Much appreciated !
I've had several instances where the CA's have been 3-5 events for most of the night and then jumps up to 6-10 (on a few instances more than 10). For example, I would have 5 CA's from 11:00 PM to 5:00 AM, go to the bathroom, put the mask back on and have 10 more CA's from 5:00 AM to 7:00 AM for a total of 15 CA's for the whole night.
I have a ResMed autoset 10 CPAP machine and have been monitoring my readings using the ResScan software (as well as Sleephead) for quite a while now. During the past week, I've been waking up around 4:00 or 5:00 AM for a bathroom break and take my mask off. When I return, I put the mask back on until I wake up for good. Before my bathroom breaks, the readings show very few CA events. During the time period between my bathroom breaks and until I wake up for good, my CA events have been doubling. It happens regardless of which side I sleep on. I don't fall back asleep all the time and when I don't, I am aware of my breathing patterns, which are normal.
Any thoughts why my CA's would double during this time frame?
Thanks
Anybody else able to weigh in on this question?
Thanks wiredgeorge. Unfortunately the cough is viral so not much will help get rid of it. OTC don’t work for me either. I have to let it take it’s course. What puzzles me is the increase in CA events while I’m clearly wide awake and conscious of my breathing. Strange. Perhaps it’s as you said, the way the machine is treating coughing spells.
Thanks for your input.
Hi,
I was diagnosed with mild SA and have been an auto CPAP (Resmed autoset 10) for the past 8 months. My AHI index numbers have been averaging between 3-6 with most of my apneas being hypopneas. I developed a dry cough a few days ago that seems to get worse if I wake up to go to the bathroom and then try to fall back asleep. The coughing keeps me up. When I finally do get up, I’ve noticed that my AHI index increased. When I review my stats on the myAir app, the increase is isolated to the time period when I was coughing. Plus, It shows I had numerous central apneas during this period as well.
Does anyone know if coughing increases your AHI (and creates central apneas) ? Is this normal?
The Pulse Oxymeter sounds like a good idea. My blood oxygen level was low during my original sleep study but I’m interested to know what it is now as a comparison.
My prescription said CPAP auto with minimum =5, maximum=12. The settings were done by the respiratory specialist, aka DME. When I was having issues with leakages from the mask, he changed the maximum to 14 for about 2 weeks. It brought my AHI down to <10 for about 4 days then it started fluctuating again. I know how to get into the clinical settings but have been hesitant to fiddle wth the settings for reasons mentioned by mad jack. I think I will take sleeptech’s advise and raise it to 14 again and see what happens.
My apology for the confusion. My AHI “index” (central apnea index + hypopneas index) is < 10 per hour, not per night, which the respiratory therapist says is within an acceptable range (5 or less being normal). However, during the last week, my AHI index has increased to over 10 per hour ( between 11-14 per hour) with the majority being hypopneas, not central apneas. So I am concerned that the increasing hypopnea index is significantly decreasing my blood oxygen levels since my understanding is that hypopneas result because of a slow down in breathing which results in lower blood oxygen levels. I’ve only been on CPAP for 3 months and they are telling me to be patient as it often takes 6 months for CPAP therapy to show positive results.
Any comments or recommendations?
My combined central apneas + hupopneas = my AHI, which are < 10 per Night, not per hour. He said since I was diagnosed with mild sleep apnea (AHI are normally between 5 and 15), my AHI's are within range. My concern was wondering if there might be a disconnect with the signal from my brain which tells me to breathe since almost half of my AHI were central apneas, but was told not to worry. Recently, my hypopneas have increased (breathing/respiratory rate slows down during the night), so now my concern is that my blood oxygen levels are becoming dangerous low. Not sure what my SPO2 levels are. All I know is that many hypopneas are directly related to low oxygen levels. Gonna give it a bit more time to see if hypopneas get better. If not, then time to insist I see the sleep doctor.
Since Sept.1, on average my central apneas have been 17 per night at my appointment with the respiratory specialist, he said that since my combined central apnea + hypopneas were <10, i have nothing to worry about Although my hypopneas are higher than my central apneas, I am concerned that there is something wrong with the message that my brain is sending telling me to breathe with my understanding would increase the central apneas numbers
