Going through this, one question popped up in my head. How could a hypopnea possibly be central?With Central sleep apnea you are either breathing or not breahing at all.Is there something like partial breathing? Like a partial airway closing in case of obstructive hypopnea .

But won't starting the CPAP without the ramp make it uncomfortable for a first time user? Also , how much ramp time do you set initially?

Also, sorry if this has been answered before, can you please explain why the autoset for her is helpful for hypopneas?

Greatly appreciated

Thanks

Ok folks.. An update on my situation. I finally had the first taste of an xpap machine at the sleep lab. It was not as bad as I thought it would be. I slept about 5 and a half hours during the test which is not bad as per my standards, though the mask kept slipping constantly and i had to adjust it through the night. A couple questions for the pundits:

1) the machine used in the sleep lab was a resmed vpap. Is vpap same as a bipap? Does it help with sleep onset apneas/ hypopneas?

2) people and experts say sleep onset centrals are normal. How come I wasn't experiencing them before and now suddenly its an issue?

As usual , thanks to this wonderful forum, in particular Sierra and sleeptech for their wonderful insight and knowledge. Without this forum, I would have felt alone in this battle.

Thanks agai My main apprehension is about wearing the CPAP mask and adjusting to it. Will it be too suffocating? What happens if the pressure is set too high?

During my first sleep test I had all the wires hooked up but no mask. I guess it is goi g to be a challenge sleeping with the mask on

Ok learned folks.. Had an appointment with the sleep doctor about my sleep study. My AHI was 19.6 , which puts me in the moderate range, I guess. What surprised me was that out of a total of 104 events in 5 and a half hours of sleep , 103 were hypopneas! There were 0 OSAs, O CSASs and 1 mixed apnea event. The doctor advised me for a CPAP titration study. I do have the following questions for the learned members: 1) Is there any way to know if these hypopneas are central or obstructive, since the report does not tell about it? The doctor was fairly confident that these are obstructive in nature , since I don't have underlying conditions for a central. 2) What to expect during a CPAP titration test , since I am quite apprehensive about it? 3) What kind of CPAP device will be best suited for my condition ?

Thanks in advance for the wonderful website and support!

I would think so but I dont normally snore so it makes me think these are mostly sleep onset CSAs. During my sleep study the technician did tell me that I had mild OSA but I am not sure if these are playing up at sleep onset or are they Sleep onset CSAs.

I dont seem to have any 10 second breathing pauses normally associated with csa.

Got an appointment with the sleep doctor on 12th of November.. Hopefully can figure out something. Yesterday was another bad night (after a couple of good ones) with only about 4 hours of sleep and weird dreams

Just out of curosity. Since I have sleep onset apnea as well, have you considered BiPap or ASV machines with backup rate feature? It seems these machines can deliver a breath or two in a a set period of time if some are missing. Not sure if they work with Onset CSAs though

Thanks .. Other than AirSense Resmed 10 are their any other CPAP/BiPap machines which help with sleep onset apneas? I have heard there are some machines which automatically detect absence of breathing for a set period of time and start it if absent. I also probably have mild OSA as per my sleep report( Though not official , i had a chance to peep into it as the tech was preparing it). The machine needs to be portable as well as O travel sometimes

Thanks for the responses. I called up the sleep medicine center and they said results would take upto four weeks! four freakin weeks! I spend upto 4 hours every night tossing and turning without sleep. I can't wait that long.. Do sleep meds help ? (I have already tried melatonin , no use). Should I ask my doc to prescribe some pills? Thanks.. and sorry for the rant..
