Do you suspect you have sleep apnea and want to take an at-home test without waiting, without spending a night in a clinic? Two technologies are prominent today: the SleepImage connected ring and the WatchPAT ONE medical watch. Two different approaches, two distinct levels of analysis. Here's how to choose the one that's right for you.
Reading time: 9 min | Delivery everywhere in Canada
Obstructive sleep apnea affects approximately 1 in 4 Canadians, and the majority of cases remain undiagnosed. For years, the only way to confirm this diagnosis was to spend a full night in a sleep lab, a long, uncomfortable process, often accompanied by a waiting list of several months. Today, two approved medical devices allow you to perform this test in the comfort of your home, in Montreal or anywhere in Canada. La Boîte à CPAP offers you access to both technologies, including delivery and professional support.
Sleep apnea: why diagnosis is urgent
Sleep apnea is not limited to snoring. It is a serious respiratory disorder where the airways partially or completely block during sleep, causing repeated micro-awakenings that fragment rest, without the person remembering them. These repeated interruptions of oxygenation to the brain and heart have well-documented consequences: high blood pressure, increased cardiovascular risk, type 2 diabetes, depression, and accidents related to drowsy driving.
The problem? Most people live with this disorder for years without knowing it. Classic symptoms such as chronic fatigue, morning headaches, and difficulty concentrating are often attributed to stress or lifestyle.

The good news: current home tests are clinically validated, accurate, and accessible. Here's how the two main technologies compare.

The SleepImage: the simplicity of the connected ring
The SleepImage is a sleep apnea screening system that uses a medical ring worn on the finger overnight.
Its operation is remarkably simple: you put the ring on your finger before sleeping, start the recording via an application on your phone, and the ring collects physiological data all night. In the morning, the data is automatically uploaded to a secure server for analysis by a doctor and a specialized respiratory therapist.
SleepImage notably measures photoplethysmography (PPG), blood flow at the finger, as well as heart rate variability, heart rhythm fragmentation, periodicity, and pulse oximetry (blood oxygen levels). The patented algorithm generates an apnea-hypopnea index (AHI) that the physician can manually review.
The WatchPAT ONE: the most comprehensive medical analysis
The WatchPAT ONE is the global benchmark for multi-sensor home sleep testing. Developed by Itamar Medical, this device is used in thousands of sleep clinics worldwide and recognized by the American Academy of Sleep Medicine (AASM) as a reliable diagnostic tool for moderate to severe apnea.
Its core technology, peripheral arterial tonometry (PAT), detects micro-changes in the blood pressure of finger vessels that occur during apneic events. By cross-referencing this signal with data from the wrist sensor, position sensor, and chest sensor, the WatchPAT accurately reconstructs your sleep cycles and identifies each respiratory event.
What the WatchPAT ONE offers in addition: detection of sleep stages (light, deep, and REM sleep), measurement of snoring levels in decibels, body position at the time of each event, and distinction between obstructive and central apnea. Its latest version also integrates the detection of atrial fibrillation, a heart rhythm disorder frequently associated with severe apnea.

Which profile for which test?
The choice between the two devices essentially depends on your clinical profile and personal preferences. Here are the typical profiles for each test:
|
Choose SleepImage if… You want the simplest and most discreet solution. Your doctor is looking for a quick initial assessment. You don't need sleep stages. |
Choose WatchPAT ONE if… You want a detailed analysis. You snore loudly. You sleep on your back. Your doctor suspects central apnea or arrhythmia. Previous borderline result. |
In all cases, both tests require a medical prescription. A prescription from your family doctor, dentist, or pulmonologist is required before ordering your kit. Once the prescription is obtained, La Boîte à CPAP delivers the device directly to your home, anywhere in Quebec and Canada, shipping included.
|
Important: Neither SleepImage nor WatchPAT replace a full laboratory polysomnography for complex cases. If your result is borderline or symptoms persist, medical follow-up is recommended. Consult our article The Importance of Medical Follow-up in Sleep Apnea for more information. |
How to order your home test
La Boîte à CPAP simplifies the diagnostic process as much as possible. Here are the concrete steps, whether you are in Montreal, Quebec City, Vancouver, or Halifax:
1. Obtain a medical prescription from your family doctor or a specialist. Mention your symptoms: snoring, chronic fatigue, morning headaches, observed breathing pauses.
2. Consult our Diagnostic Tests page to understand all available tests and choose the option suited to your clinical profile.
3. Order your SleepImage or WatchPAT ONE directly from our store. Shipping included, anywhere in Canada.
4. Perform the test at home during a normal night. Follow the app's instructions; the process is guided step by step, with no complex handling.
5. The data is analyzed by our clinical team, and the results are sent to your doctor. Depending on the conclusions, CPAP treatment can be initiated quickly.

Availability and delivery across Canada
One of the great advantages of using La Boîte à CPAP is the national accessibility of our services. Whether you live in Montreal, Longueuil, Laval, Quebec City, Ottawa, Toronto, or even a remote area, our sleep test kits are delivered directly to your home, with complete instructions and support from our team.
Our seven physical clinics are located in the Montreal metropolitan area (Villeray, Mont-Royal, Dorval, Dollard-des-Ormeaux, Longueuil) and Trois-Rivières (Nicolet, Pierreville), but our clinical reach extends across Canada thanks to our online platform and virtual consultations. If you prefer to discuss your situation before ordering, book an appointment with one of our respiratory therapists.
After diagnosis: what's next?
A positive sleep apnea test result is not bad news; it's the beginning of a solution. Continuous positive airway pressure (CPAP) treatment is currently the gold standard for moderate to severe apnea, and its effectiveness on quality of life is well established: better sleep, less fatigue, reduced cardiovascular risk, and often a noticeable improvement in mood and concentration.
La Boîte à CPAP supports its patients at every stage, from diagnosis to device adjustment, mask selection, and regular follow-up. To understand why long-term follow-up is as important as the initial diagnosis, read our article The Importance of Medical Follow-up in Sleep Apnea.
