OMNI WELL INDUSTRIAL (WUHAN) CO., LTD
C500 Mainstream ETCO2 Module
Description:
The Mainstream CO2 Sensor C500 is designed specifically for mainstream measurements using sophisticated infrared absorption spectroscopy to make EtCO2 monitoring simple and accurate, allowing for flexibility to monitor all patient (Adult/paediatric and infant ) in all environments.
With mainstream, measurements are taken directly at the patients' airway, so response is faster and there is less chance of erroneous, artifact data. The analyzer portion of the sensor cannot be contaminated with patient secretions, and there are no disposable components to C500. And the maintenance requirements and overall cost-of-ownership are minimized. Our exclusive family of airway adapters are easy to use and durable enough even for long-term intubated patients.
The Mainstream CO2 Sensor C500 can be integrated with other components, software packages and accessories, making it easy for you to configure your patient monitoring systems with state-of-the-art respiratory management and analysis technology.
Key features:
• compatible with Respironics CapnoStat5 or Phasein’s IRMA
• Warm-up time: ≤3 seconds full specification; Direct measurement without time delay
• Advanced technology of condensation compensation
• Long-life infrared detector
• No disposable accessory and airway adaptor can be used up to 100 times.
