Waking up exhausted even after a full night’s sleep? Loud snoring that keeps your partner awake? These could be signs of sleep apnea. According to Public Health Agency of Canada data, roughly 1 in 4 Canadian adults are at high risk for obstructive sleep apnea. Most remain undiagnosed, often because they assume testing means a trip to Vancouver or Victoria.
The good news? Diagnosis options have expanded. Local access has improved significantly for Vancouver Island residents. You no longer need to travel hours for answers about your sleep health.
This guide explainswhat methods are used to diagnose sleep apnea in Parksville BC. You’ll learn which path leads to better sleep without leaving the Oceanside area.
We’ll cover the two main testing types and what happens during each. You’ll also discover where to access diagnosis locally on Vancouver Island’s Oceanside corridor.
From our clinic experience:Most patients are surprised how straightforward home testing is. Many expect complicated hospital stays but find the process simple and comfortable.
What Tests Are Used to Diagnose Sleep Apnea?

Sleep apnea is diagnosed using two primary tests:
- Home Sleep Apnea Test (HSAT) — A portable device worn overnight. It tracks breathing patterns, oxygen levels, and heart rate. This test suits adults with suspected obstructive sleep apnea who don’t have other sleep disorders.
- Polysomnography (In-Lab Sleep Study) — An overnight test at a sleep clinic. Technicians monitor brain waves, eye movement, muscle activity, and breathing patterns. Doctors recommend this for complex cases or when home test results need clarification.
Both tests measure the Apnea-Hypopnea Index (AHI). This score determines how severe your sleep apnea is.

Signs You May Need a Sleep Apnea Test
Many Parksville and Qualicum Beach residents live with sleep apnea symptoms for years. They assume exhaustion is just part of aging. But certain signs suggest your body needs help breathing during sleep.
Common Symptoms to Watch For
- Loud, persistent snoring that disturbs your partner
- Gasping or choking episodes during sleep
- Daytime fatigue despite sleeping 7-8 hours
- Morning headaches and dry mouth
- Difficulty concentrating during the day
- Frequent nighttime bathroom trips
Risk Factors That Increase Your Chances
- Age 40 and older
- Excess weight, especially around the neck
- Neck circumference greater than 17 inches (men) or 16 inches (women)
- Family history of sleep apnea
- Smoking or alcohol use
Symptoms alone aren’t enough for diagnosis. Testing confirms whether you have sleep apnea and how severe it is. This matters because treatment options differ based on severity.
Untreated sleep apnea links to serious health problems. Research from the Canadian Thoracic Society connects it to heart disease, stroke, and type 2 diabetes.1 Getting tested protects more than your sleep quality.
Patient insight:One patient came to our Parksville clinic after years of assuming his fatigue was just stress from work. His wife finally convinced him to get tested after recording his snoring. His AHI score showed severe sleep apnea. Three months after starting treatment, he describes feeling “20 years younger.”
Home Sleep Apnea Test (HSAT) — How It Works
The home sleep apnea test is the most common first step in diagnosis. North Cair Medical Supplies offers this convenient option for Parksville, Qualicum Beach, and Oceanside residents. You sleep in your own bed while a small device collects data about your breathing.
What the Device Measures
- Airflow: Sensors near your nose and mouth track breathing patterns
- Blood oxygen (SpO2): A finger clip monitors oxygen levels throughout the night
- Respiratory effort: Chest bands detect how hard you’re working to breathe
- Heart rate: Continuous monitoring catches irregular rhythms
The Testing Process
- Pick up your device: Visit our Parksville clinic to collect the portable monitor. Our team shows you exactly how to use it.
- Wear it overnight: Attach the sensors before bed and sleep as you normally would.
- Return the device: Bring it back the next day for data download and analysis.
- Review your results: A sleep specialist interprets the data and discusses findings with you.
Benefits of Home Testing
- Sleep in your own comfortable bed
- No overnight hospital or clinic stay required
- Lower cost than in-lab studies
- Faster results — typically within one week
- No travel to Vancouver or Victoria
Important Limitations
Home tests work best for straightforward obstructive sleep apnea. They may miss central sleep apnea or very mild cases. Patients with heart failure, lung disease, or other sleep disorders may need in-lab testing instead.
Clinical research shows home sleep apnea tests detect moderate-to-severe obstructive sleep apnea with high accuracy in patients who have clear symptoms. If your home test is negative or inconclusive, your doctor may recommend an in-lab study for confirmation.

In-Lab Polysomnography — When It’s Recommended
Polysomnography is the gold standard for sleep apnea diagnosis. This comprehensive overnight study happens at a sleep clinic. A trained technician monitors multiple body functions while you sleep.
What Gets Monitored
- Brain waves (EEG): Tracks sleep stages and detects arousals
- Eye movements (EOG): Identifies REM sleep periods
- Muscle activity (EMG): Monitors chin and leg movements
- Heart rhythm (ECG): Detects irregularities
- Breathing sensors: Measures airflow, effort, and oxygen
- Body position: Records how sleep position affects breathing
Who Needs In-Lab Testing
- Patients with suspected central sleep apnea
- Those with other sleep disorders like narcolepsy or parasomnias
- People whose home test results were inconclusive
- Patients with significant heart or lung conditions
- Anyone needing a detailed sleep architecture analysis
What to Expect
You arrive at the sleep clinic in the evening. A technician attaches sensors to your scalp, face, chest, and legs. The wires connect to monitoring equipment nearby. Despite the setup, most patients sleep reasonably well.
The technician observes your sleep from another room. They can communicate through an intercom if needed. You’re free to move and use the washroom during the night.
Results typically take 1-2 weeks. A sleep physician reviews all the data and prepares a detailed report. This report guides treatment recommendations.
Understanding Your Results — AHI and Severity Levels
After your sleep test, you’ll receive an AHI score. This number determines your diagnosis and treatment path. Understanding what it means helps you participate in treatment decisions.
What Is the AHI Score?
AHI stands for Apnea-Hypopnea Index. It counts how many times per hour your breathing stops (apnea) or becomes shallow (hypopnea) during sleep. Higher numbers mean more severe sleep apnea.
Sleep Apnea Severity Scale
| Severity Level | AHI Score | What It Means |
| Normal | Less than 5 | No significant sleep apnea |
| Mild | 5 to 14 | Lifestyle changes may help; oral appliances an option |
| Moderate | 15 to 29 | CPAP therapy often recommended |
| Severe | 30 or higher | CPAP therapy strongly recommended; other interventions may be discussed |

Beyond the AHI Number
Your sleep specialist also considers oxygen desaturation levels. If your blood oxygen drops significantly during breathing pauses, treatment becomes more urgent. The combination of AHI and oxygen levels guides the best treatment approach.
Clinical note:Our team always walks patients through their AHI score in plain language before discussing next steps. Numbers on paper don’t tell the whole story. How you feel matters just as much as what the data shows.
