Sleep Apnea Tests

By Daren N. Hamilton

In order to confirm a diagnosis, sleep apnea tests might be ordered and completed. Typically, sleep apnea tests are performed in a sleep disorder clinic equipped with technological devices created to monitor and measure your bodily functions whilst sleeping. A patient can anticipate to invest at the least 1 night inside the clinic attached to a number of machines which will give information to specially trained staff permitting an accurate diagnosis. Following such a correct diagnosis, proper remedy can began, assuring that the dangerous complications of sleep apnea can be lowered or eliminated.

The battery of tests performed is called a sleep study Performed overnight at a dedicated sleep clinic, the patient will be observed and tested although truly sleeping. Essentially the most important and helpful part of the sleep study is called nocturnal polysomnography. In the course of the nocturnal polysomnography quite a few electrodes will likely be positioned on the patient’s head and face, whilst other sensors will likely be wrapped around the chest and abdomen. The individual tested will then lie down to sleep although the numerous sensors collect data.

A wide range of functions are assessed, starting with brain waves, measured by way of EEG (electroencephalogram). Muscle activity is monitored by EMG (electromyogram) and eye movements are tracked by EOG (electro-oculogram). The heart rate is monitored at the same time as the breathing rate and pattern along with the flow of air-intake and output by way of the mouth and nose. Systemic blood oxygen levels are tested continuously all through the testing by an oximeter attached to one of the patient’s fingers.

All measurements taken for the duration of the sleep study are recorded digitally, and the levels and patterns noted are then assessed by sleep specialists, physicians along with other researchers and professionals trained in interpreting the data gathered. Extra tests may also be performed to better inform the sleep specialist. These tests consist of blood tests for hypothyroidism or a high red blood cell count, recognized as polycythemia. This evaluation can indicate further or alternative factors for fatigue or low oxygenation. An electrocardiogram (EKG, ECG) or echo-cardiogram could be indicated to assess if the sleep disorder becoming evaluated has caused heart illness or damage. A recording or any snoring activity might also be made.

Exactly where enlarged tissues or abnormal bone structures are suspected to be obstructing airflow, a fiber-optic pharyngoscopy may possibly be performed to determine whether or not there is a structural concern, for example a narrowed airway or an airway that will not remain rigid although breathing. Occasionally a CT scan of the head and neck could be indicated where abnormally excess tissue or an overly large tongue is suspected. In some circumstances, cephalometric X-rays might be ordered to rule out deformities of the skull or other bony locations within the head or neck. Exactly where mechanical or structural troubles including these are detected, a sleep specialist may refer an affected person to an ear, nose and throat specialist to assess whether surgery is indicated as a powerful strategy to resolve the airway obstruction.

Thorough sleep disorder testing will focus attention on the causes of impaired sleep, permitting a proper therapy regimen to be instituted. As the short and long term consequences of sleep apnea may be disruptive to restful and restorative sleep for each the affected person and loved ones, and, in severe situations, can be life threatening, proper measures to eliminate or lessen sleep apnea are critical. Sleep apnea teats help sleep specialists style efficient and life-enhancing treatment.
