There may be a patch on your face below the nose, the side of your head, on your chest, the sides of your trunk, your legs – these are to get information about depth of sleep, your snoring, the movements you make, whether and when you gasp for air. (I also had this study at another hospital and I think I was observed by CCTV!!). A clip on a finger will measure continuously the levels of oxygen in your blood.
Getting to sleep
You wonder how you are possibly going to sleep with all this kit on you, but from my experience (and from what the patient in the next room told me in the morning) there was not a big problem. You probably sleep no worse than you would normally in a strange bed.
You can sit on the bed and watch TV, read a book, do a crossword or sudoku without any problem and just go to sleep when you feel is a good time for you. Nurses will check on you during the night.
At around 6 am the kit will be removed and you will be left to rest until breakfast around 8 am. A doctor will see you around 9 am but by then not all the data will have been processed - so you will be asked to come to clinic for the outcome and treatment plan.
I hope with this personal experience you will be less anxious about the sleep study. I found all the staff on Victoria keen and willing to talk about any aspect of my study and care. If your diagnosis turns out to be sleep apnoea then there is plenty of information for you available from the staff. You can also read more about my experience returning to the lab after my diagnosis with sleep apnoea for a CPAP study.
