Polysomnogram

Polysomnography | snoring remedies | snoring cures | snoring solutionsPolysomnogram is the result of a multi-parametric test called polysomnography also known as sleep study. The word polysomnogram is derived from Greek polus, which means many/much and Latin somnus, which means sleep.

 

Polysomnogram displays the comprehensive analysis of the biophysiological processes that take place during sleep. Polysomnography is often performed at night, when people sleep ordinarily, but some labs can afford performing this multi-parametric test at the patients living place at any time of the day. During polysomnography many body aspects are monitored including eye movements (EOG), heart rhythm (ECG), brain (EEG) and skeletal muscle activation or muscle activity (EMG).

 

The goal of taking polysomnography test is to determine which of the sleep disorders does the patient experience. Often those who complain of daytime sleepiness and excessive fatigue consult their physicians to pass polysomnography test.

 

As stated above polysomnogram displays the comprehensive analysis of any processes that occur in the patients body. To record all this normally 11 channels (22 wire attachments) are used. These channels measure different body aspects like EOG, ECG, EEG, EMG.

 

Polysomnography procedure is often done at a sleep lab, where patient comes in the early evening. Next hour is spent for wiring up and attaching above stated 22 wires to the patient body. A sleep technician is responsible for the whole procedure and should always remain attentive during the polysomnography test.

 

Finally, after the whole sleep process of the patient is recorded in 11 channels, physicians get polysomnogram or the results of the polysomnography multi-parametric test. The next step of the procedure is to determine the score of polysomnogram. The most influential parameters are:

  • How much time did patient need to fell asleep since light were turned off. Usually the result is less than 20 minutes.
  • The efficiency of sleep, which is the number of minutes of sleep divided by the number of minutes during which the patient was in the bed. Ordinarily this is about 85-90% or higher.
  • There are 4 sleep stages altogether. The first and the second stages are the stages of light sleep. Whereas the third stage is deep sleep stage and the fourth stage is REM or Rapid Eye Movement stage of sleep. Polysomnogram shows how many percents does each sleep stage occupy of total sleep time. Normally the percentage of the second stage is the highest and REM stage occupies just 20-25% of total sleep time.
  • Polysomnogram also displays any kind of breathing problems like obstructive sleep apnea, which is the complete blockage of airflow for about 10-15 seconds.
  • Polysomnogram also displays the leg movements during the sleep and body position as well.

After scoring has been done, the report is sent to the sleep specialist for interpretation. Interpretation is done by carefully reviewing not only polysomnogram but the whole previous medical history of the patient to determine which snoring remedies should be used to solve the problem. After the interpretation the final report is sent to your personal physician with recommentations about the remedies that should be used based on the polysomnogram.
