If you often wake up fatigued, with a headache or a dry mouth, you could have obstructive sleep apnea (OSA). It is a condition that causes blockage or narrowing of the windpipe when you’re asleep. The lack of airflow triggers a survival reflex in your brain that wakes you up just enough to breathe again. It disrupts your sleep, thereby affecting your ability to function during the day. OSA requires treatment as soon as possible since it can lead to fatal complications. If you suspect you have OSA, an at-home sleep study is a simple diagnostic tool that can help you determine if it is affecting you.
What is a Home Sleep Study?
An At-home sleep study is an easy and affordable way to find out whether you are experiencing breathing difficulties. It is performed using a simple breathing monitor that keeps track of your breathing, oxygen levels, and breathing effort while you are wearing it. Home sleep tests employ sensors that contain a tiny probe, which is placed over your finger to check your oxygen levels. More sensors will be placed on your abdomen and chest to monitor the rise and fall of your body during breathing.
Your home sleep test will typically be used for one night. It may provide a more accurate assessment of your sleep than a polysomnography test performed by sleep specialists in a lab, as the study will be conducted in the comfort of your own bed. Home sleep tests are also more accessible than polysomnography in Singapore.
Key Factors You Should Know About Home Sleep Studies
- It Monitors Breathing
A sleep study evaluates a patient by monitoring respiratory characteristics rather than sleep itself. For instance, the sleep test will not tell you how long you’ve been in light or deep sleep. Instead, it will track pauses and absences of breathing, the effort required to breathe, and whether your breathing is deep or shallow.
- It Requires a Prescription
This test cannot be purchased over the counter. It can only be prescribed for you to use at home by your primary care physician or a sleep specialist.
- It is a Minor Commitment
Most of the sleep tests conducted at home are only used for one night. It is also more affordable than a sleep study performed at a clinic.
- It is Convenient
As the sleep study is conducted in the comfort of your own home, it can result in a more accurate assessment of your sleeping habits.
Who Needs At-Home Sleep Studies?
Individuals with a moderate to high risk of sleep apnea benefit the most from at-home sleep tests. If you are debating whether you should do a sleep study at home, consider this: do you snore often? If you do, it is likely that someone has already shared this information with you. However, if you are unsure, the following are some indicators that you may have sleep apnea and should conduct an at-home sleep study:
- Having trouble with breathing at night.
- Waking up with a headache.
- Waking up with a really dry mouth.
- Daytime fatigue despite having spent enough time in bed.
How Does an At-Home Sleep Study Work?
Once a doctor has approved the use of a home sleep study, you will be provided with a device and instructions on how to use it. The test should be performed during your typical sleeping hours and position. In order to document your sleeping patterns and any symptoms you experience, you may also be asked to maintain a sleep journal.
After you have completed the test, the findings are submitted and sent to a sleep specialist. Once they review the results with you, they will determine whether you have sleep apnea and, if so, what treatment is required. Previously, kits had to be returned to a clinic; however, some are now disposable, making at-home tests rather convenient.
If your sleep apnea test results are positive, your sleep specialist may suggest further testing to confirm your diagnosis, assess the severity of the condition, identify other potential sleep disorders, and decide on possible treatment solutions.
Home Sleep Study Equipment
The following are some of the equipment you might receive for your home sleep test.
- Pulse Oximeter
A sensor on your finger that measures blood oxygen saturation, which can drop when you stop breathing due to sleep apnea.
- Respiratory Effort Sensor
Some kits utilise an attachable sensor to record the effort required to breathe, while others use an adjustable strap that is worn across the chest or abdomen.
- Nasal Cannula
Airflow during inhalation and exhalation is measured by tubes inserted into the nostrils.
- Microphone
A tiny microphone used to measure snoring is placed on the individual’s chest or neck.
- Data Collection Device
A tiny device that gathers data as well as to start and end your test.
