My psychopharmacologist recently hit the point most of my psychopharms do: no matter how much medication we throw at it, my depression and anxiety don't seem to improve past a certain "functioning" level. This never fails to cause me long nights of trying to decide if I'm a hypochondriac (if the meds aren't doing much, there must not be much wrong with me). The angst comes with a side dish of "What the hell is the goal of this, anyway? Maybe I'm not just a peppy person, this is my personality, and you can't medicate that away."
Before giving up altogether, the current doctor suggested I have a sleep study done to look for sleep apnea. Apparently sleep apnea is a clinical interest of his, so I wasn't sure I wasn't just being subjected to his favorite diagnosis, but what the hell? I'm fat, I have no energy, and I spend much of my free time either sleeping or wishing I could be sleeping; sleep apnea isn't that wild an idea. On the negative side: the sleep study is subject to a $500 deductible. Ouch.
As it turns out, the study can be scheduled within a week (I was sure it would be months for an opening), so I buy new pajamas and check the bus schedule for that part of town.
This was a split night study. The first part of the night, my sleeping was monitored. If I reached a certain threshold of "events" (that's 'not
breathing') during the first two hours of sleep, then for the second part of the night the technician would put me on a CPAP machine to see if that helped.
Thursday night I went to the sleep clinic. I was taken to what resembles a small hotel room (sort of like a European pension--it's got a bed, and enough room to walk around the bed, and what do you want more space for?) When I had filled out the various forms, I got into my pajamas, removed my contacts and eye makeup, and brushed my teeth. Following this I got to watch a 15 minute information video. Whee!
Amy, the sleep technician, took me down the hall to set up all the electrodes and such. This took 40 minutes. I had two lines threaded down through my collar and pants, one attached to each calf. These detect leg movements, identifying people with restless leg syndrome. I had two EKG electrodes, one on my side and one on my chest. An electrode was fastened to the outer corner of each eye to detect REM sleep, and two electrodes on the chin detect whether my mouth is flopping open for mouth breathing, or I'm grinding my teeth. A snore mike was taped to my throat. Four electrodes were placed on my head (after Amy made careful measurements to decide where to put them, and then applied an exfoliant and significant quantities of sticky gel crap.) There was a band around my abdomen and one around my chest to measure breathing. The chest band also had a little button on it to detect movement/orientation (like whether I'm sleeping on my back or side). I also had a nasal cannula to measure breathing and air temperature and a pulse oximeter on one finger.
While she's wiring me up, we chat, mostly about the sleep clinic. There are three technicians for six patients. I ask if Amy and her colleagues don't have sleep issues themselves, keeping this awake overnight schedule. Amy usually works Thursday, Friday and Saturday nights. Sunday morning she gets a couple hours of sleep, then retires by 8:30PM that evening. Monday-Wednesday she's on a more or less regular schedule of nighttime sleep. Amy also has a three year old, which no doubt makes the sleeping issue especially challenging.
Once all the gear's on, the box that the wires lead to is hung around my neck for ease of transport, and I trundle back to my room. Amy wants me to sample the CPAP machine, so that if I need it during the night, I won't be making my first try at it when I'm groggy. The CPAP has what looks like an oxygen mask, only it goes over the nose, not the mouth. A hose runs to the CPAP machine, which is pushing pressurized room air through my nose. The best explanation I've seen of this is that it's an "air splint": the pressurized air keeps your throat open so your airway is unobstructed. The mask is held on with a bunch of straps, and the whole rig looks like some sort of pig costume, or perhaps an S&M outfit. I discovered that opening my mouth while the CPAP is running is a bad idea--it's a weird and unpleasant sensation when the pressurized air can escape through the mouth/sinuses. Unfortunately, just like at the dentist, the technician asks me questions, so I can't help but open my mouth to answer.
At this point Amy hooks everything up to the monitoring equipment. She goes to the monitoring room and over the intercom instructs me to do various things (close your eyes, hum loudly, flex your foot) to test the equipment. Once everything is working, she turns out the lights, and I'm supposed to go to sleep.
You can see the problem here, of course. I'm in a strange place (although that might be an advantage, considering the state of my bedroom), I've got a pile of wires attached to me, and somebody's monitoring me. Rolling over is somewhere between difficult and impossible. Sleep is a while in coming.
I'm not sure I was actually asleep when Amy came in to reseat the EKG on my side, which had stopped sending signals. OK, back to sleep.
At some point, Amy came in saying something about "extending your baseline" and explaining that she was going to put me on the CPAP machine now, since I was "having plenty of events" and therefore had sleep apnea.
I took this opportunity to use the bathroom. One chunk of my hair is sticking up and pulls my scalp whenever I move. I think one of the electrode wires has gotten pulled over my head and is tangled in my hair. Amy removed the nasal cannula and strapped on the CPAP. I flopped back into bed, reminding myself to breathe through my nose. Since I also grind my teeth (I wear a night guard), I hope that keeping my mouth closed will not be a big issue. If I am mouth-breathing, Amy will come in with a chinstrap and make me look like Jacob Marley.
It's a little odd, a little claustrophobic, to be breathing through the mask, but I quickly become accustomed to it, and it doesn't cause me to panic. At one point I woke to find condensation on the inside of the mask (the CPAP humidifies the air to prevent nasty dry throat and such), which is a little gross.
Amy wakes me by 6AM. We go through the whole testing of the equipment again (flex your right foot, smile, hum), then she comes in and slings the box over my neck again so we can adjourn to an exam room, where she removes all the wires. As a technician, Amy can't tell me much; she doesn't have the proper letters after her name. She does tell me that there was a huge difference for me with and without the CPAP. I fill out some more forms, shower (and try to peel off all the gel and goop), get dressed, and leave.
The good news is that I have sleep apnea, and that I respond well to treatment with CPAP. Despite the fact that this is one more piece of equipment to haul around, one more medical condition to deal with, I'm pleased. If I can get back some energy and lose some of the daytime sleepiness, I think it would make a big difference for me. Plus, I believe the $500 deductible also applies to DME, so the health insurance company will have to foot the bill for the CPAP machine. The bad news is that my consult with the doctor isn't until the third week of November (there's that wait time I expected), so I may have to keep muddling along like this for several more weeks. My doctor told me that if I have apnea, he'll try to pressure the sleep center into putting me on a wait list for any cancellations, so I'll just keep my fingers crossed.
My two year old nephew is scheduled for a sleep study this month. I didn't ask Amy if she'd done any studies with someone that young, but I can't imagine how you keep all those electrodes and stuff on a toddler.
