Adult Sleep Study

A vari­ety of tests includ­ing Polysomno­gram, Mul­ti-Sleep Laten­cy Test ( MSLT) and Main­te­nance of Wake­ful­ness Test (MWT) are all pos­si­ble sleep stud­ies your physi­cian can order to eval­u­ate your sleep pat­terns. The DMG Sleep Cen­ter is made up of pri­vate bed­rooms and are sim­i­lar to typ­i­cal hotel rooms, with pri­vate bath­rooms avail­able for show­er­ing after the study is com­plet­ed. The rooms are sup­plied with pil­lows, blan­kets, tow­els, wash­cloths and toiletries.

The Study

  • A typ­i­cal Polysomno­gram includes the fol­low­ing measures:
    • Brain waves (elec­trodes placed on the scalp)
    • Eye move­ments (elec­trodes placed by the eyes)
    • Chin mus­cle tone (elec­trodes placed on near the chin)
    • Heart rate (elec­trodes placed on the chest)
    • Leg move­ments (elec­trodes placed on the legs)
    • Air­flow (sen­sor placed near the nose and mouth)
    • Breath­ing effort (two elas­tic belts placed around chest and abdomen)
    • Oxy­gen sat­u­ra­tion lev­el (small sen­sor attached to the fin­ger or ear lobe)
    • Audio and dig­i­tal video recording

Why is it nec­es­sary to record the above functions?

While you are asleep, the body func­tions dif­fer­ent­ly than dur­ing wake­ful­ness. Dis­turbed sleep such as paus­es in breath­ing, snor­ing and lack of sleep con­sol­i­da­tion can inter­fere with day­time activ­i­ties, cause exces­sive day­time sleepi­ness and pos­si­bly lead to seri­ous health problems.

How can I sleep or use the bath­room with all the sensors?

By pro­vid­ing a com­fort­able hotel like envi­ron­ment, we strive to make your stay at the Sleep Lab a pleas­ant expe­ri­ence. While many indi­vid­u­als wor­ry that they will not be able to fall asleep dur­ing the test, most do and we usu­al­ly obtain an ade­quate rep­re­sen­ta­tion of your sleep pat­terns. In addi­tion, the sen­sors and wires will not inter­fere with your abil­i­ty to use the bathroom.

Will the sen­sors hurt?

No. This is a pain­less and non-inva­sive test­ing pro­ce­dure. Paste is applied to your skin and scalp to keep the elec­trodes in place, but it is eas­i­ly removed with soap and warm water.

What is CPAP titration?

For CPAP (Con­tin­u­ous Pos­i­tive Air­way Pres­sure) titra­tion you will have the wires that were used for your diag­nos­tic study. Also you will be asked to sleep with a CPAP mask over your nose. The mask deliv­ers room air to keep your air­way open. This test is used to deter­mine the opti­mal pres­sure which will effec­tive­ly treat your sleep apnea and snoring.

What is mul­ti­ple sleep laten­cy test (MSLT)?

An MSLT is a day­time sleep test which is some­times per­formed in con­junc­tion with an overnight sleep study. The test con­sists of a series of day­time naps which helps us bet­ter under­stand your sleep prob­lem. Sen­sors and elec­trodes are used to record infor­ma­tion sim­i­lar to the polysomno­gram. Naps are tak­en every two hours through­out the day. Please bring some­thing to read or work to keep you occu­pied in between the naps. A tele­vi­sion and a DVD play­er are avail­able. Plan to spend the entire day pos­si­bly until 9:00 pm in the Sleep Center.

Is the sleep study cov­ered by insurance?

Most insur­ance will cov­er sleep stud­ies. We do rec­om­mend that you check with your insur­ance provider to be sure this pro­ce­dure is a paid ben­e­fit under your insur­ance plan.
