CERESENSO Disposable Thermistor Airflow Sensor – High-Sensitivity Respiratory Diagnostic Monitoring
CERESENSO Disposable Thermistor Airflow Sensors deliver reliable, continuous nasal and oral thermal airflow monitoring for Polysomnography (PSG) sleep diagnostic studies. Engineered with precision thermistor elements, this single-use sensor converts breath temperature changes into clear, high-amplitude electrical signals, enabling sleep technicians and physicians to accurately identify and score Obstructive, Central, and Mixed Apnea as well as subtle Hypopnea events.
Featuring dual flexible nasal elements and a dedicated oral drop element, the sensor captures temperature differentials from both nose and mouth breathers effortlessly. Terminated with standard 1.5mm touch-proof Safety DIN connectors, it plugs directly into standard AC thermal airflow channels on major PSG headboxes.
Key Features & Advanced Thermistor Sensing Technology
Designed for busy hospital sleep centers and home sleep testing (HSAT) providers who require premium signal fidelity and zero maintenance.
- High-Sensitivity Dual Nasal & Oral Detection: Engineered with three fast-response thermistor beads (two nasal, one oral) for comprehensive coverage of all breathing patterns.
- 100% Single-Patient Use Hygiene: Single-use design adheres strictly to hospital infection control standards, protecting patients and eliminating post-study cleaning time.
- Robust Signal Output: Delivers superior signal amplitude and stable waveforms, making it easier to distinguish true hypopneas from baseline noise.
- Universal Safety DIN Connectors: Color-coded 1.5mm touch-proof Safety DIN connectors (blue/gray) fit securely into standard clinical PSG headboxes.
Ergonomic Design & Patient Comfort
Thoughtfully built to stay securely in place overnight without causing skin redness or patient wakefulness.
- Lightweight Molded Centerpiece: Compact housing stamped with the CERESENSO logo sits comfortably under the nose without weighing down on the upper lip.
- Pliable Thermistor Elements: Adjustable elements allow easy, customized positioning near the nostrils and mouth to maximize temperature sensitivity.
- Flexible Lead Cables: Lightweight, tangle-resistant cabling minimizes tension and prevents displacement caused by patient position shifts during sleep.
Broad Applications in Sleep Medicine & Respiratory Diagnostics
Ideal for hospital sleep diagnostic labs, outpatient sleep centers, home sleep testing providers, and medical supply distributors.

Frequently Asked Questions (FAQ)
What is the difference between a thermistor and a thermocouple airflow sensor?
Both sensors detect temperature changes from breathing. A thermistor uses temperature-sensitive resistors that yield higher signal voltage and sensitivity, making it excellent for detecting hypopneas. A thermocouple generates micro-voltages passively from temperature gradients without external circuit excitation.
Is this disposable thermistor airflow sensor compatible with my PSG system?
Yes. Fitted with standard 1.5mm touch-proof Safety DIN connectors, this sensor plugs directly into the thermal airflow AC channel inputs of Cadwell, Respironics Alice, Embla, Compumedics, and SleepSense-compatible headboxes.
Why choose disposable thermistor sensors over reusable ones?
Disposable sensors remove the risk of cross-contamination between patients and eliminate the labor-intensive cleaning, sanitizing, and inspection required for reusable sensors, significantly lowering lab operational costs.
Can this sensor be ordered in bulk with private label branding?
Yes. CERESENSO provides OEM custom manufacturing, private labeling, and custom box packaging for medical distributors and sleep diagnostic equipment vendors worldwide.
