CSA. Cheyne Stokes? ASV or CPAP?
Hi All
First time poster here. I had been struggling with sleep for a few months before doing an at home sleep study privately. The results from the sleep study did not provide much information. I had an AHI of 7.5 with my lowest SpO2 of 91. I shared my concern of central sleep apnea with the doctor who dismissed me and said its very rare and unlikely. He advised me that it was most likely insomnia and I should commence with Sleep Hygiene, Sleep restriction and Sleep Efficiency programmes. I did this for a few months with no improvement.
Prior to the sleep study, out of the blue, I would struggle to fall asleep and as I would fall asleep, I would stop breathing and wake up. This would happen a number of times before I would eventually fall asleep. I would then wake up a few times through the night with the same thing and then start the cycle over. Im a fit, healthy 32 year old male. I've been exercising and doing spinning classes twice a week for the past 2 months. I tracked my sleep with an apple watch (not sure if this has been useful at all). I also tracked my sleep to confirm that I do not snore. My wife has confirmed this too.
Unfortunately I do not have private heath care/insurance and I would be lowest priority to go through the public health care system to get an in lab sleep study so I could probably wait 6 - 9 months. I decided to buy a 2nd hand ResMed Mini Cpap in an attempt to reduce or stop the events from happening. This also never helped me at all, the Mini does not provide much data but it did show me the number of events which fluctuated between 5-20 events a night.
I have decided to approach a supplier who offers private trials and sales of ResMed machines. After explaining my situation and presenting my sleep study results I started a trial on a ResMed Air Sense 10 AutoSet. I have downloaded the info and used sleepyhead to view it. It seems to confirm what I had suspected. The events are not very high but what bothers me is the duration and that I continuously wake up from it. If I were sleeping through the night I probably would not notice aside from headaches, sighing and yawning during the day. I assume my chemoreceptors are not functioning correctly and my CO2 levels are not in balance.
Looking at my charts, does it look like Cheyne Stokes or periodic breathing? You'll also note note the length of the Centrals are between 10-24 seconds.
Because I'm going private I'll buy which ever machine will be best for me. If an ASV is recommended, there is one that is available for me to purchase. I would like to stop wasting time with the Air Sense if the AirCurve ASV would be better? I have reduced the pressure to 6.2 max which seems to reduce the number of events but not the duration. I'm aware of the restriction on the LVEF for the AirCurve ASV PaceWave. Any assistance would be greatly appreciated.
Kind regards
Jonno
