Airflow Sensor
Our airflow sensors are the primary channel for apnea and hypopnea detection in sleep studies, available in two advanced technologies: thermistor and thermocouple.
Thermistor airflow sensors are reliable, cost-effective, and ideal for routine clinical PSG, featuring a triple-thermistor array for accurate waveform reproduction. Thermocouple airflow sensors offer higher sensitivity, faster response time, and low-noise signals — perfect for research and detecting subtle flow limitations.
All our PSG airflow sensors come with system-specific connectors (keyhole, 2.5mm audio, 1.5mm DIN) for seamless integration with Alice, Grael, Nihon Kohden, Cadwell, and Compumedics systems.
Body Position
Accurate sleep posture monitoring is essential for diagnosing positional sleep apnea. Our body position sensors use triaxial accelerometer technology to precisely detect five standard sleep postures: supine, prone, left lateral, right lateral, and sitting.
Designed for seamless integration with major PSG systems (Alice 6, Grael, Natus, Cadwell, PSG-1100), these sensors provide stable DC voltage output, requiring no additional software or calibration — ideal for overnight sleep studies.
Compact and lightweight, our PSG body position sensors attach easily to thoracic respiratory belts, ensuring patient comfort and reliable data throughout all-night monitoring.
Pressure Cannulas
Our disposable nasal pressure cannulas are critical for accurate airflow monitoring in sleep diagnostics, prioritizing infection control with single-patient use design.
Featuring universal Luer Lock connectors (male/female), these cannulas fit virtually all PSG and HSAT devices, eliminating the need for adapters. Soft, pliable nasal prongs and 2.0-meter flexible tubing ensure patient comfort and high-fidelity airflow signals.
Disposable design eliminates cross-contamination risks, reduces reprocessing labor costs, and ensures sterile use for every patient — perfect for hospital sleep labs and home sleep testing.
Respiratory Effort Sensors
Respiratory effort sensors are essential for distinguishing between obstructive and central sleep apnea, providing reliable signals for AASM-compliant event scoring.
We offer two technologies: RIP (Respiratory Inductive Plethysmography) belts for quantitative effort measurement, and piezoelectric sensors for cost-effective routine clinical use.
Our PSG respiratory effort sensors are compatible with PSG-1100, Cadwell, Alice 6, Grael, and Embla systems, featuring standard 1.5mm DIN or keyhole connectors for seamless integration.
RIP Belt
RIP (Respiratory Inductive Plethysmography) belts are the AASM-recommended method for quantitative respiratory effort measurement in polysomnography.
Our RIP belts feature insulated wire coils that generate linear, accurate signals proportional to chest and abdominal movement — ideal for detecting paradoxical breathing and distinguishing obstructive from central apnea.
Compatible with Alice 6, Embla, Grael, and Nightone systems, these soft elastic belts ensure patient comfort during all-night studies, with keyhole connectors for seamless PSG integration.
Snore sensor
Accurate snoring detection is critical for assessing upper airway resistance syndrome (UARS) and improving respiratory event scoring. Our snore sensors use two advanced technologies: microphone and piezo.
Microphone snore sensors capture subtle neck vibrations for high sensitivity, while piezo sensors use crystal technology to avoid ambient noise — perfect for multi-system labs.
Compatible with Alice 6, Grael, PSG-1100, Cadwell, and Compumedics systems, these low-profile sensors attach easily to the neck, ensuring patient comfort and clear signal output.
Disposable SpO2 sensor
Accurate arterial oxygen saturation (SpO2) monitoring is critical for identifying sleep apnea events, evaluating oxygen desaturation index (ODI), and ensuring precise respiratory scoring during sleep studies. Our disposable SpO2 sensors utilize skin-friendly elastic fabric wraps combined with highly sensitive optical technology to deliver artifact-free waveforms.
Designed with a standard 9-pin connector, these sensors offer exceptional multi-system compatibility, integrating seamlessly with major PSG and diagnostic sleep platforms. The flexible, hypoallergenic fabric strip wraps securely and comfortably around adult fingers or neonatal feet, eliminating cross-infection risks while maintaining consistent signal quality throughout overnight monitoring.
Pressure sensor
Accurate airflow pressure detection is essential for identifying sleep apnea, evaluating upper airway resistance, and delivering precise respiratory event scoring. Our pressure sensors utilize advanced AC and DC piezo crystal technologies to accurately monitor nasal-oral pressure changes and separate them into high-fidelity airflow and snore diagnostic signals.
Ceresenso pressure sensors are engineered to avoid ambient noise and electrical interference, providing clean, artifact-free baselines even in complex multi-system laboratories. Designed with dedicated connector options, these low-profile, passive sensors offer direct plug-and-play compatibility with Alice 5, Alice 6, and other mainstream PSG systems, ensuring ultimate patient comfort and dependable signal stability throughout clinical sleep studies.
