Carole made great time on the drive home from Cambria, and we were early enough for me to pick up my motorcycle at home and drive back to the hospital. My ticket for the parking garage was stamped 7:37pm, plenty of time to make my 7:45pm check-in time.
Huntington's staff in admitting were very professional. After check-in, I waited with a nice guy named Daniel, who seemed to be in his late twenties. We discussed our reasons for being there, jobs - the usual stuff. The polysomnographers met us in the admitting lobby around 8:20pm and escorted us to the study area.
After a brief review of the process, I changed into my sleeping clothes and brushed my teeth. (I was going to wear my new silk pj's, but chose swim trunks instead to make it easier to attach the leads on my legs.)
Laura then started to hook up all the leads needed for the study. First was an elastic belt around my waist (to measure the effort I spend breathing), and another around my upper chest (to measure overall respirations). Next I sat in a chair in the lobby area, and three or four leads were placed in my scalp - it was most uncomfortable when she scraped my sunburned areas to prep for the leads - just like an EEG. Two leads were put on my chest to monitor my heart, then one by each eye to measure eye movement; one on the front of my neck (to sense snoring) and one on the back of my neck (which Laura didn't explain), and finally a lead was put on each side of my jaw to measure teeth grinding.
I went in my room to read for about half an hour while Laura hooked up another patient. Next, we tried on three different CPAP masks for fit and comfort. Only the first one fit well, and none were comfortable. Laura explained that my doctor had ordered a split study - if she noticed certain respiration patterns, she was to come in and fit a CPAP mask for the rest of the night.
Laura then had me lay down on my bed, and a lead was placed on each calf to measure leg movements. Finally, a pulse-ox sensor was taped to my right index finger and a nasal sensor was fitted, and I was ready. I felt like a Borg, and was no certain that sleep would come easily. I spent a few minutes doing various movements so Laura could calibrate the instruments, followed by lights-out at around 10:30pm. Laura instructed me to sleep on my back for 30-45 minutes. The room was somewhat warm, so I was on top of the covers.
I don't normally sleep on my back, so after what seemed like a long enough time I carefully rolled onto my side. When I sleep on my right side, I usually put my right hand under my right cheek, but the glowing LED pulse-ox sensor made that impractical.
At some point during the night the A/C came on and pulled half the quilt over me. I finally had to find a way to delicately get all the way under the covers, and pulled one of my scalp lead out. Laura came in to re-glue it, and re-taped my leg leads while she was at it.
The rest of the night was weird - a lot like the way I sleep when I'm backpacking. I had a couple of different dreams - in one I was reffing a soccer game, and another I was watching waves hitting a rocky shore - but I didn't feel like I slept well. I woke up around 6:30am and felt rested, but not totally.
Laura came in and disconnected all the leads, with only moderate discomfort. I cleaned up as best I could using a washcloth and a towel, and changed back into the clothes I wore last night.
I mentioned that she had not come in with a mask during the night, and she said no, she hadn't. The results go to Dr. Shubin for analysis, but the lack of a mask seems to indicate that I don't have obstructive sleep apnea.
I filled out a one-page questionaire, said good bye to Laura, and shuffled out to the parking garage. There was no one in the booth to take my $3 on the way out.
I had a decaf Americano and a low-fat muffin at the nearby Starbucks and read the Thursday LA Times. The short ride to work was cold. The shower was quite pleasant, in spite of the poor state of the shower head, the interminable time it takes to get hot water, and the sunburn on my scalp.
