Mainstream Capnograph

QuRe® sensor is intended to measure FiCO2 and EtCO2 concentration in the mainstream breathing.

Designed to use with medical devices for intensive care, ventilation, respiratory support and patient monitoring.

The sensor is applicable for all intubated patients from adults to neonates.

QuRe® sensor benefits:

  • The most acurate capnogram.
  • Compact and lightweight.
  • Long-life time reusable airway adapters, up to 100 sterilization cycles.
  • Suitable for high-frequency ventilation, up to 200 bpm.
  • No user calibration required.
  • "Everything on board": the measurement channel and analysis CPU are inside the sensor. This saves space in your own medical devices.
  • Easy integration to any monitoring or ventilation systems, full technical support by the Manufacturer.
  • Private labeling solutions (PLM) available.
  • Fastest response time.


The highest precision of capnogram waveform for true clinical diagnostics

QuRe® date rate is 100 Hz and instant accurate response of the sensor to the changing CO2 concentration.
The sensor contains an innovative ultrafast semiconductor emitter with a high modulation frequency of the signal.
Due to the precise capnography waveform, the clinicians can analyze each breathing cycle, detect respiratory disorders and provide optimal ventilation mode to a patient.
