Think you might have sleep apnea but don’t like the idea of spending a night in a sleep laboratory? You are not alone — and the good news is that there is a simpler, more convenient option available.

At CPAP Experts Philippines, we offer the Level 3 Home Sleep Apnea Test (HSAT) — a portable, easy-to-use sleep diagnostic test that you can do in the comfort of your own bed. No unfamiliar clinic rooms. No overnight stays. Just you, your bed, and a small monitoring device that does all the work while you sleep.

Here is everything you need to know.

What is a Level 3 Home Sleep Apnea Test (HSAT)?

A Level 3 HSAT is a portable sleep test designed primarily to evaluate whether an adult has obstructive sleep apnea (OSA) — the most common sleep disorder, where breathing repeatedly stops and starts throughout the night.

Instead of sleeping in a clinic, you wear a compact monitoring device in your own bed. Depending on the device configuration, it monitors:

• Airflow — detecting breathing patterns and interruptions
• Blood oxygen levels (SpO₂) — measuring drops in oxygen during sleep
• Pulse and heart rate
• Breathing effort
• Body position during sleep
• Snoring

At CPAP Experts Philippines, we use the BMC PolyWatch — a compact, clinically validated portable Level 3 device designed specifically for home testing.

How is HSAT Different from a Level 1 PSG?

The biggest difference between a Level 3 HSAT and a Level 1 Polysomnogram (PSG) is the amount of information collected.

A Level 1 PSG is the most comprehensive sleep study available. It monitors brain activity, eye movements, muscle activity, heart rhythm, breathing patterns, and more — giving a highly detailed picture of your sleep.

A Level 3 HSAT focuses primarily on breathing and related signals. It uses fewer sensors and is performed at home — making it far more convenient, though with some limitations.

	Level 1 PSG	Level 3 HSAT
Setting	In-clinic (supervised)	At home
Sensors	10+ parameters	5-6 parameters
Brain waves monitored	Yes	No
Technologist present	Yes	No
Best for	Complex/severe cases	Suspected moderate-severe OSA
Convenience	Requires clinic visit	Done at home

For uncomplicated adults at increased risk of moderate-to-severe OSA, an HSAT is an appropriate and reliable alternative to an in-clinic PSG. If the home test results are negative, inconclusive, or technically inadequate but sleep apnea is still suspected, an in-lab Level 1 PSG may be recommended.

How Does It Work? Step by Step

The process is designed to be as simple and stress-free as possible:

Step 1 — Assessment and Booking First, discuss your symptoms and sleep concerns with a healthcare professional to determine whether a Level 3 HSAT is the right option for you. Contact our team at CPAP Experts to get started.

Step 2 — Receive the Equipment We provide you with the BMC PolyWatch portable testing device, along with clear instructions on how to use it.

Step 3 — Set Up the Device at Home Before bed, you apply the sensors yourself following our step-by-step instructions. The setup is simple and straightforward — no technical expertise required.

Step 4 — Sleep Normally Put the device on, go to sleep as you normally would, and let the BMC PolyWatch do all the work. It records your breathing, oxygen levels, pulse, and other relevant signals throughout the night.

Step 5 — Return the Device After the recording night, you return the device to our team so the data can be extracted and reviewed.

Step 6 — Clinical Interpretation and Results The recorded data is reviewed and interpreted by a qualified sleep physician, who determines whether the findings are consistent with sleep apnea and recommends the appropriate next steps. Results are then provided to you or your authorized healthcare provider.

Who is the Level 3 HSAT For?

A home sleep apnea test is ideal for:

• Adults with symptoms or risk factors suggesting obstructive sleep apnea — such as loud snoring, gasping during sleep, excessive daytime sleepiness, or morning headaches
• Patients who prefer to sleep in their own environment rather than a clinical setting
• Patients outside Metro Manila who cannot easily travel to a sleep clinic
• Patients looking for a more affordable diagnostic option
• Patients who want a quicker, more convenient path to diagnosis

Note: HSAT is not a general screening test for everyone. A healthcare professional should first assess whether an HSAT is appropriate for your specific situation. Patients with complex medical conditions or suspected non-OSA sleep disorders may be better served by a full Level 1 PSG.

The BMC PolyWatch — Our Home Sleep Test Device

At CPAP Experts Philippines, we use the BMC PolyWatch for our Level 3 HSAT service.

The BMC PolyWatch is a compact, portable device designed for home use. It records key measurements including:

• Airflow
• Oxygen saturation (SpO₂)
• Pulse rate
• Respiratory effort
• Body position
• Snoring

Its simple design allows patients to apply the sensors themselves with minimal difficulty — making it one of the most patient-friendly home sleep testing options available.

What Happens After the Test?

Once your results are ready, our clinical team will walk you through your findings and recommend the appropriate next steps. If sleep apnea is confirmed, we will guide you toward the right treatment — whether that is CPAP therapy, BiPAP therapy, or another solution tailored to your needs.

At CPAP Experts Philippines, we do not just hand you a diagnosis and send you on your way. We are with you from the first test to long-term therapy support.
