What where the results of your first sleep study?

[Lurch]

Mine were pretty shocking. Sever sleep apnea with no REM sleep.

My was interesting, especially during the time that I spent with the attractive tech girl after lights were out.

Out of the 8 hours I thought I slept, I actually slept 4 hours with an AHI of 17. No REM sleep. Said I slept lightly, but I sure don't remember anything.

My Dx was Severe OSA. AHI of 94 associated with frequent mild to moderate desaturations and marked sleep fragmentation. The sleep MD also said i had Sleep Onset Insomnia but I told him they expected me to go to sleep at 10PM when my normal was after the late, late show. But I've reformed and get to bed earlier.

I need to follow-up on the O2 desat and use a home monitor some night to see what's going on there. My mean SpO2 was 89% with the lowest at 82%.

Inconclusive, my #'s were all over the place. Tried to titrate me on CPAP and I did not tolerate it well and had to go back for a 2nd study on an ASV. OSA, CSA and other crap. That's my official diagnosis.

The results of my study were shocking, not because of the severity, but because it came back with sleep apnea. My sleep doctor didn't suspect it at all. My only symptom was excessive daytime sleepiness. She was leaning toward narcolepsy or idiopathic hypersomnia. Scheduled me for the PSG mostly just because it's required before the MSLT. Of course, after the PSG, they sent me home without doing the MSLT. AHI only came back at 15.1, which isn't terrible. I'd much rather have apnea than narcolepsy anyway. One is treated mechanically, the other is treated with expensive drugs.

The results of my first sleep study 20 years ago were OSA, nocturnal myoclonus, and possible narcolepsy. They minimized the OSA, saying that an AHI of 9.9 (all hypopneas in REM) was just "shallow breathing in REM". What's more surprising are the results of the rest of my sleep studies. On the next study they ruled out narcolepsy, retracted the OSA, and left me with just the nocturnal myoclonus (=PLMS). The next couple they just diagnosed me Idiopathic Hypersomnia, and sometimes PLMS. 19 years after the first study, I was diagnosed with OSA (funny enough, all from hypopneas in REM). I should write a letter to the first doctor to let him know how my "shallow breathing in REM" has worked out for me over the past couple of decades.

My FIRST sleep study was a joke. That was about 17 years ago. I had warned the tech that I had PVC's that were harmless, but during the middle of the night I woke up with a cardiologist standing over me asking if I'd ever had a heart attack. The only thing that the doctor who'd ordered the test (a neurologist) told me was that I did not have sleep apnea. I wasn't assertive enough at the time to demand more answers.

My baseline done last year showed I had over 30 minutes until sleep onset and another hour and a half before REM. I had 277 PLM's. My AHI was 19 on my back and much less on my side. I was stunned to see how quickly I changed stages of sleep; I didn't realize they can change that quickly. And it confirmed that I wake up over 40 times per hour, with about 20 times being fully awake during the 6 hour study.

When I went in for my sleep study I was told that they test the first night and if you had Apnea then they would test another night. A couple of hours in the tech came in and put a mask on me and I finished the night with it on. In the morning I was told they were worried that I was going to have a stroke or heart attack as my blood oxygen levels were in the 50’e and I stopped breathing over 140 times an hour. Sleep Apnea testing was in its infancy and the rules that techs have to abide by were not in effect yet so I was informed about my results right away. I had a combination of restless leg syndrome and severe obstructive Sleep Apnea, added to my lower lung capacity from at that time 20 years of heavy smoking; which left me pretty useless in my job as a mill operator. Cpap is the only reason that I am here today and I am convinced that I would have died without it.

First and only (split) sleep study in August, 2010. AHI 21.3 (supine 37., SpO2 was 90-100% only 64% of the time, PLM 8.2, REM Index 96.9%.

Right from when the sleep tech slapped a mask on my face it was obvious XPAP was going to work for me. Results with mask - AHI 0.5, (supine 0.6), SpO2 90-100% 93% of the time, PLM 3.2, REM Index 0.0%.

My AHI hasn't made it to 1.0 since starting on CPAP, however it was two months between my sleep study and the appointment with my neurologist and DME providing me with the gear.

First one was in 1998. I had an AHI of 91. Was set at a pressure of 12. Now I'm on ASV because of centrals (that they said I had in the first study but because I didn't have insurance I couldn't afford another study). Now in 2011 I'm finally being treated for the centrals I have been having this whole time.

My diagnostic study revealed moderate sleep apnea based on an RDI of 23.1 and minimal O2 desats; there were 85 respiratory events scored in 238.5 minutes of sleep. The vast majority of my respiratory events (78 of 85 events) were "hypopneas with arousal"---i.e. hypopneas that could be scored under the AASM Alternate rules because they all resulted in EEG arousals, but none of them had significant enough O2 desats to qualify as hyponeas under the AASM Recommended rules. According to my new doc, if I was a medicare patient, my "official" AHI would have been 3.5 (based on 14 OAs and 0 Hypops scored under the Recommended standard in 238.5 minutes of SLEEP) and medicare would have (initially) denied coverage, but she would have appealed such a decision because of the RDI.

I also had pretty lousy sleep efficiency at 69.7%. Sleep efficiency has been really bad on all my titration studies too: 73.7% on the CPAP titration; 28.8% on the first BiPAP titration; and 66.6% on the second BiPAP titration.
