What Is a Home Sleep Monitoring System?
A home sleep monitoring system is a portable diagnostic device that records multiple physiological and environmental signals during sleep outside a traditional laboratory setting. BMC Medical PolyWatch YH-S900B and YH-S900C are designed for home and clinical environments, where recorded information can support professional sleep assessment.
The systems are intended for adults and for children aged six years and above who weigh at least 20 kg, with the age and weight criteria interpreted together. Always confirm the current instructions for use and intended-use language before deployment.
For readers comparing treatment pathways, sleep apnea monitoring should be considered separately from therapy selection. The PolyWatch system records data; it does not replace qualified clinical interpretation.
Portable sleep diagnostic equipment for structured sleep assessment.
Choose the PolyWatch Configuration
Both systems support broad multi-parameter monitoring. The principal distinction is the connectivity and ECG capability specified for each model.
YH-S900C
Bluetooth + WiFi- Includes five-lead ECG.
- Bluetooth and WiFi wireless data transmission.
- WiFi data transmission is supported.
- Local data reading is supported.
What You Get
Capture multiple signals: record airflow, breathing effort, oxygen, pulse, position, movement, and related parameters in one monitoring workflow.
Support home assessment: use portable equipment in a home environment while keeping professional interpretation central.
Wear the system comfortably: use a dual-host configuration, silicone watchband, rounded design, and wrist-worn color touchscreen.
Adjust the interaction: configure left- or right-hand wearing, screen brightness, swipe navigation, and simplified controls.
Monitor for an extended session: the brochure states that two hours of charging supports at least 16 hours of continuous monitoring.
Maintain signal control: use medical-grade sensors, high-precision algorithms, respiratory belts, and a metal Luer connector designed to reduce tube breakage or detachment risk.
For users researching respiratory inductance plethysmography, the PolyWatch design uses chest and abdominal belts to sense thoracic and abdominal respiratory activity.
How It Works
Step 1
Prepare and Wear
Apply the wrist-worn system, chest and abdominal belts, and required sensors according to the current instructions for use.
What the user sees: a compact device and guided wearing setup.
Step 2
Record Sleep Signals
The system records airflow, respiratory movement, oxygen, pulse, body position, movement, and other supported parameters during monitoring.
What the user sees: status information through the screen and hidden breathing light.
Step 3
Review With a Professional
Recorded information is read through the supported pathway and interpreted by a qualified healthcare professional.
What the user sees: recorded data prepared for clinical assessment.

FAQs
Who is the PolyWatch system intended for?+
The system is presented for adults and children aged six years and above who weigh at least 20 kg. The age and weight criteria should be interpreted together. Confirm the current instructions for use and intended-use language before selecting or using the device.
Which model includes five-lead ECG?+
Five-lead ECG is specified for the YH-S900C. It is not included in the YH-S900B capability list provided for this page. Confirm the market-specific product configuration and current documentation before ordering.
What does the system measure?+
The listed parameters include pressure airflow, airflow waveform, pressure snoring, chest and abdominal breathing, blood oxygen, pulse rate, pulse wave, ambient light, body position, body movement, and CPAP pressure. The YH-S900C additionally lists five-lead ECG. The exact available channels depend on the model and configuration.
Can the PolyWatch system diagnose sleep apnea by itself?+
The device should not be presented as independently diagnosing a condition without professional interpretation. It records sleep-related data for assessment by a qualified healthcare professional. Recorded information does not replace clinical evaluation, diagnosis, or treatment.
How does connectivity work?+
Both models list Bluetooth data transmission, while WiFi transmission is listed for the YH-S900C. Local data reading is supported, and related PAP Link pathways can vary by device, region, connectivity, and account setup.
