Polysomnography is a sleep test, which is also referred to as a sleep study test, which is a diagnostic test that is implemented to monitor the way the body operates when it is asleep. The test captures breathing patterns, oxygenation levels, heart rate, brain activity and body movement to help in the diagnosis of sleep disorders like sleep apnea, insomnia and other sleeping disorders involving breathing. The sleep research could be conducted in a sleep laboratory at a hospital or at home with the help of the portable sleep monitoring equipment which records the overnight sleep data.
The test assists physicians to learn the behavior of breathing and sleep cycles throughout the night to detect sleep disorders and prescribe the appropriate therapy.
Physicians typically recommend the sleep study when one exhibits indications of a broken sleep or problems with breathing when asleep. Such cases are usually hard to detect in normal medical check ups.
Obstructive sleep apnea, which is a condition where breathing stops and starts multiple times as one sleeps, is one of the most prevalent conditions that is diagnosed by sleep testing.
A sleep study is a study which monitors multiple body functions at the same time in order to see how the body performs in regards to behavior during sleep.
The test typically measures:
Using these signals, specialists in the study of sleep can conclude whether sleep cycles are not normalized or whether there are some breathing abnormalities during sleep.
The studies of sleep are divided according to the degree of monitoring needed to identify the sleep disorders.
Level 1 sleep research is done during the night at a sleep laboratory in a hospital and is done by closely observing the breast waves, respiration, heart rate, oxygenation, and muscle activity. This is the most advanced type of sleep testing.
The studies of level 2 sleep are also conducted in their homes with the help of portable sleep study devices. This is the alternative that enables the patients to sleep in their routine home and still get the appropriate diagnostic findings.
Level 3 sleep tests are reduced versions that are primarily applied in the diagnosis of sleep disorders associated with breathing as is the case with sleep apnea. The tests are related to monitoring the airflow, oxygen level, and heart rate.
The machine used to test sleep is seen in the figure below:
Contemporary sleep research involves portable diagnostic devices, which have sensors, which monitor physiological processes during the night.
The machine that is needed in a sleep study might look like:
These sensors record sleep data during sleep time and this data is further examined by sleep professionals to provide diagnosis of potential sleep disorders.
The usage of home sleep studies has evolved as an acceptable substitute to the old sleep lab tests. They enable patients to be taken through diagnostic tests without having to spend the night in a hospital.
This process mainly involves:
This would enable the patients to take the test at their comfortable position and yet get the correct diagnostic results.
In India, the price of a sleep study test at home is different and depends on the type of sleep study and level of monitoring.
Common price ranges are:
Level 3 Home Sleep Study ₹2,000 – ₹6,000
Level 2 Home Sleep Study ₹5,000 – ₹10,000
Level 1 Sleep Lab Study ₹10,000 – ₹25,000
Home sleep measures are typically less expensive and less invasive than their hospital sleep lab counterparts.
A sleeping disorder study could be ordered when a person has a constant sleep disorder or sleep apnea symptoms.
A sleep study may be necessary in case you have:
Timely diagnosis will be able to promote the quality of sleep and avoid complications in the case of sleeping disorders, which are not treated.
Sleep disorders may influence general wellbeing, vitality and living standards. Sleep study test at home gives important information concerning the breathing patterns, oxygen levels, and sleep cycles and this enables the doctors to diagnose sleep conditions like sleep apnea correctly.
Modern portable sleep study machines used by patients have allowed many patients to now perform sleep testing at the comfort of their home and still achieve good diagnostic findings.
What is the purpose of sleep study test?
The diagnosis of sleep disorder is carried out through the use of a sleep study test which involves the process of observing breathing, oxygen levels, brain activity and body movements during sleep. It assists physicians in diagnosing sleeping disorders like sleep apnea and other sleeping disorders.
What is the cost of a sleep test study in India?
In India, the average price of a sleep study test is between 2000 and 25000 rupees depending on the kind of examination and follow up. Hospital based sleep lab tests tend to be more expensive than those conducted in the home.
Is it possible to do sleep study test at home?
Yes, one can do sleep studies at home by use of portable monitoring devices that measure the breathing pattern, the oxygen content in the blood and the heart rate during sleep. Sleep apnea is usually diagnosed by home sleep studies.
What is the time duration of a sleep study test?
A sleep test generally involves a single night study of approximately six to eight hours. At this period, the monitoring device captures sleep activity and patterns of breathing to analyze them.
Is a sleep study test painful?
No, a sleep study is nothing painful. The test does not leave any invasive processes, and small sensors are required to record sleep data attached to the body.
