Do you suffer from loud snoring, excessive daytime sleepiness, or breathing pauses during sleep? Are you wondering how to get a sleep apnea test to identify the cause? Getting an accurate diagnosis is essential to improving your sleep quality, preserving your overall health, and optimizing your daily performance.
The process includes symptom assessment, consultation with a sleep specialist , and a sleep study to determine the type and severity of sleep apnea. Whether through a home test or laboratory analysis, this guide explains each step to help you regain restful sleep and access appropriate treatment.
What is sleep apnea?
Sleep apnea is a sleep disorder characterized by repeated pauses in breathing during sleep. These pauses, called apneas, disrupt sleep cycles and reduce blood oxygen levels, leading to serious health risks such as heart disease, high blood pressure, and a decreased quality of life.
Types of sleep apnea
- Obstructive sleep apnea (OSA): The most common type of sleep apnea, OSA, occurs when the throat muscles relax excessively, blocking the upper airway during sleep.
- Central sleep apnea (CSA): This type results from a malfunction of the brain in sending the appropriate signals to control breathing.
- Complex sleep apnea syndrome: A combination of OSA and ACS, this condition requires specialized treatment.
Symptoms of sleep apnea
- Loud snoring: Loud, chronic snoring is a common symptom of sleep apnea, often caused by air struggling to pass through an obstructed airway. Bed partners often notice this early sign of breathing difficulties during sleep.
- Breathing breaks: Sleep apnea causes repeated interruptions in breathing, lasting from a few seconds to several minutes. These pauses reduce oxygen levels, disrupt sleep, and cause micro-awakenings, resulting in poor sleep quality and daytime fatigue.
- Excessive daytime sleepiness: Daytime sleepiness results from frequent interruptions in breathing, disrupting the sleep cycle. People with sleep apnea often suffer from fatigue, difficulty concentrating, and an increased risk of accidents in their daily or professional activities.
- Morning headaches: Frequent headaches upon waking can be caused by low oxygenation and poor blood circulation due to sleep apnea. These headaches often disappear during the day but indicate underlying breathing problems during sleep.
- Episodes of suffocation or choking during sleep: Many people with sleep apnea experience sudden episodes of choking or gasping as their body tries to resume normal breathing. These episodes can wake both the affected person and their partner, further disrupting restful sleep.

Why get tested for sleep apnea?
If left untreated , sleep apnea can lead to serious health complications, including heart failure, stroke, and the worsening of certain pre-existing conditions. Testing provides an accurate diagnosis and paves the way for effective treatments such as Continuous Positive Airway Pressure (CPAP) therapy, oral appliances, or surgery.
How to get a sleep apnea test
To be tested for sleep apnea, start by discussing symptoms such as snoring, daytime sleepiness, or breathing pauses with your doctor. They can then refer you to a sleep specialist for a more thorough evaluation.
Depending on your symptoms and risk factors, you may undergo a sleep study in a laboratory or a home sleep apnea test. These tests monitor breathing, oxygen levels, and sleep patterns to determine the severity and type of sleep apnea.
Types of sleep apnea tests
Sleep apnea tests are essential for diagnosing this common disorder and assessing its severity. From at-home options to laboratory studies, these tests monitor breathing patterns, oxygen levels, and much more to develop a treatment plan tailored for better sleep.
Nighttime oximetry
Nocturnal oximetry is a simple, non-invasive test that measures blood oxygen levels and heart rate during the night. A small device, usually worn on a finger, tracks changes in oxygen saturation, which can indicate breathing interruptions during sleep. While not a standalone diagnostic tool, nocturnal oximetry is often used as a preliminary screening for sleep apnea or to monitor the effectiveness of treatment.
Cardiorespiratory polygraphy
Cardiopulmonary polygraphy is a portable test that monitors key indicators such as breathing patterns, heart rate, oxygen levels, and chest movements. Unlike a full sleep study, it does not measure brain activity or sleep stages. This test is useful for diagnosing moderate to severe obstructive sleep apnea in adults, providing valuable information without requiring an overnight stay in a sleep clinic.
Home sleep apnea test
A home sleep apnea test (HSAT) is a convenient diagnostic tool for identifying sleep apnea. Patients wear a device that measures breathing, oxygen levels, and airflow during sleep. The HSAT is designed for individuals at high risk of moderate to severe sleep apnea, offering an accessible and cost-effective alternative to laboratory testing while ensuring an accurate diagnosis.

4 steps to get tested for sleep apnea
Getting tested for sleep apnea involves several essential steps for accurate diagnosis and effective treatment. From identifying symptoms to consulting a sleep specialist, including sleep studies and obtaining results, this process allows for addressing nighttime breathing problems and improving health, sleep quality, and overall well-being.
Step 1: Recognize the risk factors
Certain factors increase the risk of sleep apnea, including:
- Neck circumference : A wider neck is associated with obstructive sleep apnea.
- Body weight : A high body mass index (BMI) increases the risk of sleep apnea.
- Enlarged tissues : Excess tissue in the throat or soft tissues can obstruct the airways during sleep.
- Tobacco and substances : Nicotine from tobacco relaxes the muscles of the throat and worsens symptoms.
- Sleeping position : Lying on your back can exacerbate breathing interruptions.
Step 2: Consult a healthcare professional
Start by consulting your primary care physician or a sleep specialist. They will assess your symptoms, medical history, and potential risk factors. For a more detailed diagnosis, you may be referred to a sleep clinic or center.
Step 3: Take a sleep apnea test
Depending on your symptoms and health status, your medical team will recommend one of the following tests :
- Laboratory sleep studies : Also called polysomnography, these studies measure oxygen levels, chest and leg movements, and air pressure in the airways over an entire night.
- Home sleep apnea tests : These tests measure events per hour, oxygen levels, and breathing patterns to identify mild to severe apnea.
Step 4: Get your results
Results are usually available in 2 to 4 business days. Your sleep specialist will explain the findings, including the severity of your sleep apnea and the number of breathing interruptions per hour. Once you have your results, contact a CPAP therapy specialist to help you choose the best CPAP machine and products to treat your sleep apnea.

Treatments for sleep apnea
An accurate diagnosis is essential to determine the best treatment, which varies depending on the type and severity of sleep apnea. Options include CPAP therapy, oral appliances, lifestyle changes, or surgery. Treating sleep apnea not only improves sleep quality but also reduces health risks, such as heart disease and daytime sleepiness.
CPAP Therapy
Continuous Positive Airway Pressure (CPAP) therapy is a highly effective treatment for obstructive sleep apnea. A PAP device, used with a CPAP mask, delivers a constant air pressure to prevent airway obstructions during sleep. This therapy improves breathing patterns, reduces daytime symptoms, and enhances the overall quality of life for people with sleep apnea.
Dental orthotics
Custom-made dental appliances are an effective option for treating mild to moderate obstructive sleep apnea. These devices adjust the position of the jaw or tongue to keep the airways open during sleep. Easy to use and portable, dental appliances offer a comfortable alternative to CPAP therapy for many people.
Lifestyle changes
Adopting healthier habits can reduce the symptoms of sleep apnea. Maintaining a healthy weight, avoiding sedatives or alcohol before bed, and engaging in regular physical activity improve breathing during sleep. Simple adjustments, such as changing sleeping position or using nasal breathing devices, also contribute to better sleep health and overall well-being.
surgical treatment
Surgery may be recommended in severe cases of sleep apnea or when other treatments are ineffective. Procedures may include the removal of enlarged tissue, the correction of structural abnormalities, or the widening of the upper airways. Surgical treatment aims to correct the underlying physical causes, providing lasting relief and improved breathing during sleep.
