You should not take coffee or tea or alcohol on the day of sleep study.
The technician must be informed about special cases of fits, obstructive sleep apnea or partial paralysis so that he is aware of what medication you prefer in case of an incident.
For patients who need to go to the bathroom in the night, notifying the technician of such intermittent requirements before the procedure begins and during the course of the study, is important.
Other measures that you can take before the procedure include carrying comfortable night clothing with you so that you can change and be comfortable even in the new surroundings. In addition to this, you also can carry a tablet, laptop or iPod to listen to your favourite music or watch movies.
After the set-up is done make sure to check your ease of use and try out the two-way speakerphone before the procedure begins. You are allowed to carry your favourite bedtime pillow, soft toy and even your bedtime snack to be kept in the fridge usually provided in the sleep room. The sleep study is usually complete after you wake up.
The wires and attachments are removed in few minutes. Some facilities might provide you with showers and that can help you freshen up and move out for the day. You may need to continue in the same facility if daytime tests like MSLT or MWT are due.
There are no extra precautions to be taken after the procedure except in cases where you may notice local irritation or allergy on your skin where the sensory electrodes were placed. Visit a skin doctor to find the right ointment that has to be used to get rid of this affliction. The reports are not provided to the patient instantly and are released after one or a couple of weeks only after being reviewed by a sleep specialist.
