What is a Sleep Study?

A sleep study, otherwise known as a polysomnography test is a device that monitors your sleep at night. Most sleep studies are performed to diagnose obstructive sleep apnoea, and occasionally Upper Airways Resistance Syndrome. Sometimes they can be used to diagnose other diseases such as Restless Legs Syndrome, or Epilepsy.
Sleep Studies are performed over one night and can be either performed at home or in a hospital. Normally if you are worried about Obstructive Sleep Apnoea or Upper Airways Resistance Syndrome, then a study performed at home is all you need. If your doctor suggests that you need a sleep study done in a hospital overnight, then they will be also checking for epilepsy (as they will require a video recording of the sleeping patient). Restless legs syndrome can be diagnosed at home, and does not require an inpatient stay, but often a video recording is very useful. A Sleep Study done in a hospital is often called a Polysomnography.


What is it like to have a Sleep Study?

A sleep study is a non-invasive test, and does not cause any pain or side effects. The device is a smartphone-sized box which is attached via elastic bands that gently wraps around your chest and stomach. There are a number of other cables that are needed to collect data:

  • There is a monitor that sits on your finger which monitors pulse rate and oxygen levels in your blood.
  • The elastic straps that go around your chest are there to monitor how hard you are trying to breathe at night.
  • The one around your stomach is compared to the one around your chest, and that provides information about people who are struggling to breathe at night (the chest and stomach move in different directions when someone is trying to breathe against a blockage).
  • There is sometimes a cable that runs around your nose and monitors the airflow at whilst you breathe. This is very important when you are trying to diagnose Upper Airways Resistance Syndrome.
  • There can be a number of other cables that lead to you head or legs to diagnose other conditions.

There is a similar set up for children as seen in the image below.

What is pulse oximetry?

Pulse oximetry is just the device that sits on your finger at night (monitoring heart rate and oxygen levels in the blood. Mr Vik Veer does not recommend the use of these devices as they are unable to detect most problems during sleep. It will only pick up very obvious severe sleep apnoea but in Mr Vik Veer’s experience it misses significant problems with sleep disordered breathing. Mr Vik Veer has met a number of people who have had a pulse oximetry test (which is mainly used by Respiratory teams who provide CPAP), who were then told that they have no problem after the test. When they go on to have a proper sleep study they find out that in fact they have a treatable sleep disorder which helps them with their tiredness and other symptoms. If you know you will only accept CPAP as a treatment option, then a pulse oximetry would be a reasonable choice.
Pulse Oximetry is often used for children in the NHS to work out if they should undergo an adenotonsillectomy to solve their sleep apnoea problem. Mr Vik Veer still advocates a proper sleep study even in children.


How can I get a Sleep Study done?

Mr Vik Veer provides a courier service where a state-of-the-art sleep study machine is sent directly to your home / workplace. You would then use the device that night in the comfort of your own bed, and then the courier will return the next day to pick up the device. This avoids having to travel into central London to pick up a device and return it by hand the next day. Because of the courier, this sleep study option is now a national service. Now anyone in the country is able to have a sleep study done whenever they wish. To get the results you may want to have a formal report written for you by Mr Vik Veer or if you prefer you can visit Mr Vik Veer in his London clinics to discuss the results face-to-face.

What information can be gained from the NoxT3 Sleep Study

The NoxT3 sleep study provides a wealth of information for analysis. Not only does it provide accurate information about the number of times someone stops breathing at night (AHI), but it also provides an ODI result (the number of times the patient stops breathing and if it causes a loss of oxygen in the blood). Importantly for Upper Airways Resistance Syndrome the NoxT3 also measures the airflow and how it is being resistricted. It also measures how much effort the patient is making to try and breathe. People who work hard to breathe all night often do rather well on less advanced sleep studies, but when you look at the effort they are making to breathe, it is no wonder why these people are so tired in the morning. Fighting to breathe all night is extremely tiring, and this aspect is often missed in other sleep studies. Oxygen levels, heart rate anomalies, and if necessary information about snoring, brain activity, leg movements, and even bruxism (grinding teeth whilst sleeping.
All of these measurements are supported by positional information which provide a great depth of information. You can therefore see which side you need to sleep on to snore less or breathe better. Sometimes patients are classified as having severe obstructive sleep apnoea and are given a CPAP machine to treat it. However if you look at the positional data, often these patients just need to be trained to sleep on their side at night to completely resolve their obstructive sleep apnoea (OSA).
