A powerful platform of Microstream™ capnography

The Microstream™ microMediCO2 OEM module is the core component of Microstream™ etCOmeasurement technology. Smaller and lower power than previous models, the microMediCO2 OEM module can be designed into an even wider range of host configurations.

With less power required, the Microstream™ microMediCO2 OEM module makes etCO2 monitoring simple and accurate, even in the smallest and most portable monitors.


  • Measures etCO2, FiCO2, respiration rate
  • Clear, crisp CO2 waveforms, even in non-intubated patients
  • Highly accurate CO2 values, even in variable breathing conditions
  • Small, compact size
  • Rugged, reliable technology
  • Fast on power up; fully accurate at first reading
  • Low sampling flow rate of 50 ml/min, required for neonates
  • Low power consumption
  • RS-232, USB
  • RoHS compliant
  • Full suite of Smart Capnography™ algorithms
    • Integrated Pulmonary Index™ (IPI), measuring adequacy of ventilation and oxygenation
    • Smart Breath Detection™ Algorithm (Smart BDA), mitigating the effects of artifact, enabling quality monitoring for non-intubated general floor patients
    • Smart Alarm for Respiratory Analysis™ (SARA), to recognize and reduce nuisance alarms, promoting caregiver alarm vigilance.
    • Apnea-Sat Alert™ measuring apneas per hour and Oxygen Desaturation Index values to identify and quantify apneas and oxygen desaturation events.
  • etCO2 sampling solutions for all environments and patient populations
    • Adult, pediatric, neonate
    • Intubated (standard and high humidity)
    • Non-intubated (nasal, oral/nasal), with an option for O2 delivery, standard and high humidity
    • Smart CapnoLine™ guardian provides continuous nasal and oral CO2 monitoring and oral O2 delivery in upper endoscopy patients without compromise of patient position or endoscopic technique
  • Easy to integrate and versatile for all clinical applications and environments:
    • Procedural sedation 
    • General care floor
    • ICU – ventilation management, weaning and post weaning ventilation monitoring
    • NICU
    • Emergency department and prehospital EMS
    • Resuscitation environment 
    • Sleep labs
  • Complete OEM integration kit and technical support
