A polysomnogram is a procedure which records your child's sleeping patterns. Each study may vary depending on your child's needs and the physicians' request. Some of the recordings include:

* Brain waves -- sensors placed on the head
* Heart beat -- sensors placed on the chest
* Eye movements -- sensors placed above and below the eyes
* Leg movements -- sensors placed on the lower leg
* Breathing -- sensors placed under the nose or near the mouth
* Breathing effort and chest movement -- small belts placed around the chest and stomach
* Oxygen levels -- adhesive strip type sensor attached to the finger

Is this procedure really help to detect the actual problem of sleep?
