Sleep is essential for your health and well-being, yet sleep disorders like obstructive sleep apnoea (OSA) can disrupt this important aspect of life. Diagnosing such conditions often requires a sleep study, but did you know there are four different types of sleep studies, each with its own level of accuracy and suitability? Let’s learn these types and help you understand which is best for your needs.
What Are Sleep Studies?
Sleep studies, called polysomnography, monitor your sleep patterns, breathing, heart rate, oxygen levels, and other vital signs to diagnose sleep disorders. These studies are performed in various settings, from the comfort of your home to specialised labs. Each type offers a unique balance of convenience, accuracy, and cost.
4 Types of Sleep Studies
1. Type 1: The Gold Standard
Type 1 studies are conducted in sleep laboratories or hospital settings and provide the most comprehensive diagnostic data. A trained sleep technician monitors patients overnight, collecting extensive measurements such as:
- Brain activity (EEG)
- Eye movements (EOG)
- Muscle activity (EMG)
- Heart rate (ECG)
- Breathing patterns and oxygen saturation
This type of study is ideal for diagnosing complex cases or multiple disorders. However, it requires an overnight stay in a medical facility, which can be inconvenient for many patients. Fortunately, Medicare covers Type 1 studies, making them more accessible when medically necessary.
2. Type 2: The Best for At-Home Comfort
Type 2 studies offer nearly the same diagnostic accuracy as Type 1 but are conducted in the comfort of your home. Patients are equipped with portable devices that monitor multiple parameters, including airflow, oxygen levels, and body position.
Why Type 2 Stands Out:
- Convenience: No need for hospital stays; you sleep in your bed.
- Accuracy: Comprehensive data collection ensures reliable results.
- Cost-Effectiveness: Medicare covers Type 2 studies, and at CPAP Adelaide, we bulk bill, so it’s entirely free for patients.
These studies are perfect for diagnosing moderate to severe OSA while maintaining the comfort of home.
3. Type 3: Limited Monitoring
Type 3 studies are simpler, using fewer sensors to monitor basic parameters like:
- Airflow
- Oxygen saturation
- Heart rate
While less comprehensive than Types 1 and 2, Type 3 studies are suitable for mild to moderate sleep apnoea cases. However, they may not capture the full scope of sleep disorders, requiring further testing in some cases.
4. Type 4: Basic Screening
Type 4 studies are the most minimal, often using single-channel devices to measure one or two metrics, such as oxygen levels or heart rate. These studies are primarily used for preliminary screening rather than definitive diagnosis. While they’re quick and easy, their limited data makes them the least reliable option for diagnosing sleep disorders.

What to Expect During a Type 2 Sleep Study
-
Booking Your Study
Start by contacting CPAP Adelaide to book your Type 2 sleep study. Our team will guide you through the process and schedule a time to collect or deliver your monitoring equipment. -
Setting Up at Home
The provided device comes with easy-to-follow instructions. Attach the sensors as directed—usually on your chest, fingers, and near your nose—and go to sleep as usual. -
Collecting Data Overnight
The device records critical metrics, including:
- Breathing patterns
- Blood oxygen levels
- Heart rate
-
Analysis and Follow-Up
Return the equipment the next day, and our specialists will analyse the data. If a sleep disorder is detected, we’ll work with you to create a personalised treatment plan, often involving CPAP therapy.
The Importance of Medicare Coverage
Sleep studies, particularly in-lab options, can be costly. Medicare makes these essential tests more affordable by covering Type 1 and Type 2 studies. At CPAP Adelaide, we go a step further by bulk billing Type 2 studies, ensuring every patient is included due to financial constraints.
What Happens After Your Sleep Study?
If your sleep study confirms a diagnosis like OSA, the next step is treatment. CPAP therapy is a proven solution for managing OSA, improving sleep quality, and preventing complications like heart disease. CPAP Adelaide offers a range of CPAP machines, masks, and accessories to suit every patient’s needs, along with expert advice to help you get started.
Choosing the Right Sleep Study for Your Needs
When deciding on a sleep study, consider the following:
- Type 1: Best for complex cases requiring in-lab monitoring.
- Type 2: Ideal for reliable, at-home diagnosis with comprehensive data.
- Type 3: Suitable for simpler cases but less detailed.
- Type 4: A quick screening option with limited reliability.
For most patients, Type 2 strikes the best balance between convenience and accuracy, especially when combined with bulk billing at CPAP Adelaide.
