A Sleep Study
What to expect at a Sleep Study
Once you're wired up for the sleep study, it would be extremely difficult to go to the toilet as all the electrodes would have to be removed, so go beforehand. Otherwise, it would have to be the bottle.
You'll need the usual stuff, tooth-brush, towel and soap etc. You'll probably get a evening drink of tea, but don't expect a chocolate biscuit unless you're Robert Retford. This photo was taken at St. James Hospital, Leeds where I spent the night. The room was sparse but comfortable.
Note: There is no mask over your face, so there's nothing to worry about. A home sleep study is sometimes possible, depending on availability in your area. This is a small portable device easily carried. You are shown how to attach the sensors and connect everything up before taking it home for the night.
A typical Sleep Study Setup
- Movement sensors attached to the legs to check muscle activity
- Chest band to detect the motion of the ribcage
- Various chest electrodes to monitor the heart
- Microphone around the neck to record snoring level
- Heat sensors under the nose and below the mouth to detect expired air
- Finger stall to measure the blood oxygen level
- Some clinics may have a video camera set up

A CPAP Evaluation Test
This is very strange to wear and I had difficulty getting to sleep with it. It was like wearing a Aqua-Lung as it didn't give you air until you inhaled. This is what's called a negative pressure system. If you don't suck, you don't get any air. A CPAP machine is a positive pressure system that constantly feeds air at a higher pressure than normal, so there's always an excess.
