Sleep Study Analysis – A thorough Analysis by Dr.Muthus Hospitals Experts
In today’s fast-paced life, sleep might be a concern for people of any age group. There are many people who find it a real struggle to fall asleep. If you are struggling with any sleep issues, then Dr.Muthus Hospitals specialists are there to support you.
Understand polysomnography - a comprehensive test for diagnosing sleep disorders
Polysomnography is known as a study (comprehensive test) for diagnosing sleep disorders. It works by recording waves in your brain, level of oxygen in your blood, breathing and heart rate, leg and eye movements in the study. You can order a sleep disorder test from us but without understanding from our experts, you may find it more confusing than informational. So, here we are going to offer you different steps to comprehend the report of your sleep study analysis:-
RDI and AHI indexes
AHI stands for apnea-hypopnea index, this is called a definite metric for determining whether a patient is suffering from sleep apnea or not. It calculates an average number of hypopneas and apneas. In other words, respiratory events contribute to this that causes a specific airflow decrease that a patient is experiencing per hour. You can get to know it as sleeping is normal if AHI is greater than 5 per hour. It is mild, less than 5 per hour but greater than 15 per hour. Moderate, if it is lesser than 15 per hour and more than 30 per hour and severe lesser than 30.
Sleep disruptions, Ieg movements, and arousals
This is known as sleep apnea. In fact, it has a very confined picture of the brain and respiratory-related events that may disrupt the sleep of a patient. Many varied events may be a matter of concern. Apneas might be the most known trait of such a sleep disorder. These happen if a patient stops breathing for around 10 seconds. However, hypopnea, partial airflow cessation, may prove to be serious. There are also respiratory-based arousals that may disrupt your deep sleep or breathing without getting qualified for the mentioned events. Moreover, our offered sleep study provides a report on the excessive movement of the legs. We take all such factors into consideration while making an assessment of quality sleep.
Stages of sleep
Humans have varying sleep stages during the night such as N1, 2, 3, and REM sleep. Adults usually go through these stages many times per night. This cycle might be fragmented and disrupted due to specific sleep disorders and making it impossible for a patient to have a revitalizing and normal rest. For example, sleep apnea may result in arousal that stops people from going into the deepest sleep stage. In the absence of a good cycle, they cannot feel recharged. At the time of sleep study, we use brain monitors to keep a good track of the sleep stage that you experience and allow the technicians to observe sleep irregularities.
Position of the body
Like sleep stages, the position of the body also impacts sleep apnea severity. Our specialists talk with the patient in detail and also check the sleep postures of the patients themselves. For a sleep study, they ask the patient to sleep on his back for a defined time and observe him deeply. They also study sleep according to the time spent on the right side, left side, on the stomach, and on the back.
SaO2 (oxygen desaturation)
If a patient stops breathing on a regular basis during his sleep, it means that he is not getting enough oxygen into his bloodstream as per his requirement. Your oxygen saturation is measured by the percentage of oxygen in your body that a patient inhales actually. For people suffering from sleep apnea, the level of their oxygen may fall under 60%. This indicates that the patient is getting half oxygen of their requirement. If this saturation drops below 95%, your body and brain are not inhaling enough oxygen. This may cause cardiovascular issues and brain damage. \
After the above-mentioned studies, the next step is suggesting the best therapies. Here comes the next step by Dr.Muthus Hospitals experts:-
- Depending upon the sleep study analysis, the physician working on the case may suggest the next level sleep study analysis of CPAP therapy. Below are some of the best examples:-
- In case, a patient has a PSG baseline that indicates sleep apnea. This may further demand a return to a CPAP titration.
- In case, the CPAP titration has not been completed, then a physician may require returning for the next CPAP titration or it may be bi-level titration.
- For people who have a successful CPAP titration, then a CPAP setup can be scheduled.
Other tests that are recommended for sleep apnea
- EEG also called electroencephalogram is used for recording and measuring brain wave activity.
- EOG is also known as electrooculogram and is recommended for recording eye movements. These movements are considered crucial for determining the varied sleep stages, especially REM stage sleep.
- EMG, also called an electromyogram, is used for recording muscle activities such as teeth grinding, leg movements, twitches, and REM stage sleep. EKG also known as electrocardiogram is recommended for recording the rhythm and heart rate of a patient.
Our sleep study analysis offers the best account of what was recorded in six to eight hours sleep. Our physicians review the study report as well as correlate the patient as per the sleep complaints. As per the observation, we suggest the best clinical management decisions to normalize the sleep patterns and lead to practice a hygiene sleep, avoid over-the-counter sleeping aids and prescription hypnotics. Thus, opt for our sleep study analysis and notice changes within a defined time.
FAQs
This is a comprehensive test that is recommended for exploring sleep disorders. With certain tests, sleep is tested by recording oxygen levels within the blood, waves in the brain, breathing, leg movements, and heart rate. So, sleep disorder is determined with a deep sleep study analysis.
During a sleep study analysis, a patient is monitored with his breathing as well as CPAP pressure adjustment for determining an ample air pressure that is needed for stopping upper airways clogging, removing breathing pauses during sleep. CPAP titration is done for brain waves, heart rate, breathing, oxygen level, leg and arm movements.
You might be advised to avoid food or drinking having caffeine or alcohol during the afternoon or evening before you are going for polysomnography. Caffeine or alcohol may change the sleep pattern, and might be responsible for worsening sleep disorders. And, you are also advised to avoid napping in the afternoon before you go for a sleep study analysis.
The test conducted for sleep study analysis remains non-invasive and it is not painful. The environment of the lab is kept quiet, dark, and conducive for sleeping. However, the presence of wires and electrodes sometimes affect some patients’ sleep. In case you are concerned about your sleep during the process of sleep testing, you are suggested to take less sleep earlier at night or you can wake up earlier than other days.
