The Microstream™ Technology Advantage

Microstream™ capnography technology uses Molecular Correlation Spectroscopy™ a proprietary CO2-specific IR wavelength engineered to deliver clear, crisp waveforms and accurate measurements, with no impact from the presence of other gases (i.e., O2, N2O, He, or inhaled anaesthetics).With fast power-up and fully accurate measurements at first reading, Microstream™ technology offers:Low flow 50-mL/minute sample rate, effective for virtually all patient types and necessary for neonatal samplingNo individual patient calibration or rezeroing requiredProprietary Smart Capnography™ algorithms, Smart Breath Detection™ algorithm (SBD) and Smart Alarm for Respiratory Analysis™ algorithm (SARA), are designed to simplify the use of CO2 monitoring on Microstream™ technology-enabled patient monitors to help improve patient safety and clinical workflow.([FOOTNOTE=Internal test data on file. ],[ANCHOR=],[LINK=])

Microstream™ Advance Filter Lines

Design enhancements help improve the patient experience and the performance of the sampling line. Softer tubing may help increase patient compliance and safety, while the improved kink-resistance of the tubing maintains an uninterrupted oxygen supply to patients, and continuous CO2 sampling.([FOOTNOTE=Blonder Y, Mazor E, and Jew K. Advanced capnography sampling lines may improve patient comfort and compliance. Med Devices (Auckl). 2021; 14 37-42.],[ANCHOR=],[LINK=])

Microstream™ Advance filter lines offer:

  • Soft tubing and neutral scent to help improve patient compliance
  • Intubated and nonintubated options for short-term and long-term monitoring
  • 0.2-micron sterilizing-grade filter designed to help reduce risk1 of biohazard contamination of the monitor
  • Uni-junction™ technology, designed for effective sampling with and without oxygen delivery, from both nares and the mouth, even at low tidal volumes
  • Kink-resistant tubing engineered to mitigate interrupted oxygen flow and resulting alarms, meets ISO 13544-2 compliance standard
