Last Friday marked the first time I ever spent the night in a hospital. Fortunately, I was able to walk in under my own power. As I approached Admissions, the staffer immediately said “Sleep Study?” She said it was pretty easy to recognize folks coming in to the sleep clinic, as they were carrying an overnight bag and usually their own pillow. I would also bet that virtually all of them are overweight older men.
I checked into the sleep clinic at St. Vincent’s at 8:00 pm and was escorted to a small room with a bed and a complete nocturnal surveillance system, including a remote-controlled low-light camera and an overhead microphone. I watched a short film that explained sleep apnea, and went into detail as to exactly how hard it is on your system to slightly suffocate a hundred times each night.
Then I got wired. Leesa, my polysomnographic technologist (love that title) started fitting me with the sensors she would use to monitor my sleep. By the time she was done, I was wearing:
- two sensor bands, one around my chest under my arms, one at my waist
- EKG electrodes on chest and back
- microphone taped to the base of my throat
- two electrodes on each calf to monitor restless leg syndrome
- a dozen electrodes on my scalp and face
- a thermocouple wire taped under my nose to detect exhalation
- a blood oxygen monitor on my right index finger
I looked funky.
Leesa told me that they would monitor my sleep patterns, and if they determined that I was, in fact, suffering from sleep apnea, they would wake me up to fit me with a CPAP and attempt to titrate the pressure. That is, they would try to determine the positive pressure that the CPAP needed to deliver to prevent the apnea.
I took a sleeping pill, which was itself ironic, since one of the reasons I was undertaking the study was my chronic sleepiness, and they turned out the lights.
The next thing I knew, Leesa was attempting to reattach two of the electrodes on my scalp. I had, of course, sweated enough to wash off the cement attaching them to my scalp. Then she put a facemask on me, and air started getting pumped into my nose. It was an odd sensation. Then she left, and after a few minutes, I drifted back to sleep.
At 6:00, I was awakened. The face mask was still in place. Leesa began taking off the various wires and sensors. I asked he if I had indeed been exhibiting apnea. She assured me that they wouldn’t have put the CPAP on me if I hadn’t. Unfortunately, they hadn’t been able to completely titrate the pressure needed, so I couldn’t take a CPAP home. But I should make an appointment with my primary care physician to go over the results from the sleep study and I would get one then.
So, how did I feel? Well, I was only wearing the CPAP for maybe half the night, but even so I felt pretty chipper all day. I can only imagine that having a full night’s quality sleep will be a truly restorative process again.
And no more snoring.
