Undergoing a Sleep Test at Bangkok Hospital

I snore. I snore so loudly that it keeps Tawn awake. After trying various remedies such as weight loss and sleeping on my side, I decided to visit an Ear,Nose, and Throat specialist at Bangkok Hospital. After sticking a probe up my nostrils to inspect that things were roughly in order, he suggested I come in for an overnight sleep test.

The purpose of the test is to get an accurate read on the quality of your sleep including your sleep patterns, physical movement, brain activity, and breathing. Sleep apnea is a condition often associated with snoring. You stop breathing for extended periods of time (more than ten seconds), which can lead to many health problems including irritability, fatigue, and high blood pressure.

P1200799 I arrived on a Thursday evening at the hospital. After having my vital signs taken, I went for a pair of chest x-rays. (I have to say, before coming to Thailand, I had never had an x-ray in my life. In the six years since, I’ve had close to a dozen. They really like their x-rays here.) Then I headed upstairs to the sleep clinic.

My room for the evening resembled a regular hotel room, but with linoleum floors and bedside equipment that reminded you that this was a hospital. The room was also outfitted with two cameras, one of which was infrared, that would allow the sleep technician to observe me throughout the night.

After changing into my hospital scrubs, the sleep technician started wiring me up. This took about thirty minutes and my recurring thought was that this must be roughly what a condemned man goes through leading up to his execution. Grim, no?

Electrodes were attached to various parts of my body. Having a shaved head made this process easier, I think. A tube was inserted into my nostrils. Straps around my belly and chest held wires and monitors in place. Finally, all the wires were pulled together like a ponytail and wrapped with medical tape.

When it was time to go to bed, I had to carefully position myself on the mattress. The technician stretched the wires across the bed to a trio of small devices, which then fed the data directly to the computers in his hidden control room. After saying goodnight to Tawn, I read for a little while until sleepy, finally turning out the light and shutting my eyes.

Once the thoughts of imminent execution left my mind, I kept repeating the question, “How can this really measure anything useful?” With this number of wires, electrodes, and monitors, my range of motion was limited. Add to that the unfamiliar bed and pillow and the fact that I usually fall asleep on my side before rolling over onto my back, and I was carrying more negative, skeptical thoughts than usual. I had been offered a mild sedative if I thought I would be unable to sleep, but declined it. After not too many minutes, however, I did manage to drift off to dream land.

Sometime in the middle of the night, I awoke for about thirty minutes. I was thirsty and had to stretch awkwardly to reach a bottle of water on the bedstand. Instead of fully quenching my thirst, I merely sipped because if I subsequently needed to use the toilet, I would need to call the technician and be unplugged first.

I slept a restless few more hours before finally waking at 5:30. It didn’t take long before I decided that I had had enough of this experience and wanted to get up. I was surprised when the technician, perhaps reading my brain waves, entered the room about fifteen minutes after waking to unwire me without me having to ring for him.

Afterwards, I showered and changed into my street clothes, letting the nurse know I would skip the included breakfast and was ready to be discharged. By 6:30 I was home, taking care not to wake up Tawn who was enjoying a peaceful, snore-free night.

A few days later I returned to the hospital for my follow-up meeting. While I didn’t feel like my night had produced a representative sample of my sleeping habits, the doctor was confident of the test results. He explained that I suffer from a condition known as “regular snoring” and that I have no sleep apnea. All of the measures – blood oxygen, brain waves, sleep modes, etc. – we within a normal range. Whether I do anything further to treat the snoring is up to me, but it is posing no health risks at this point.

In retrospect, I have to give the Bangkok Hospital staff high marks for professionalism and attentive service. While I think the package might be a little steep at about US$500 (Why do they need to x-ray me, for example?) the experience was a positive one. My doubts about the effectiveness of the test may linger, just slightly, but at least I know that my health is in no immediate danger.
