Engineered for accuracy 

The Microstream™ capnography monitoring system integrates filter lines, advanced hardware, and sophisticated algorithms to deliver precise EtCO₂ readings and provide critical insights for patients across all care settings.


Engineered to outperform imitations

In bench testing against competitive sampling lines, only the Microstream™ Advance filter line consistently performed to specification across all tested metrics.1 Sampling lines that imitate the Microstream™ Advance connector exhibited inconsistent performance, suggesting that cross paired sampling lines may fail to deliver reliable, consistent, or accurate measurements.

Reliable EtCO2 measurements

Microstream™ Advance filter lines are designed for accuracy and account for variations in nasal passage anatomy and nasal obstructions2 to provide reliable EtCO2 measurements.​

  • Our Uni-junction™ technology is designed for effective sampling from both nares and the mouth - even at low tidal volumes - while minimizing the impact of oxygen flow and high respiratory rates.​

  • Delivers oxygen to both nares and the mouth by creating an “oxygen cloud” designed to provide consistent FiO2 for both oral and nasal breathers.​

Reduce alarm fatigue and improve clinical efficacy

Our Smart Capnography™ algorithms help simplify the use of EtCO2 monitoring while improving patient safety and clinical workflow.

Our Smart Breath Detection™ (SBD) and Smart Alarm for Respiratory Analysis™ (SARA) algorithms screen out low-amplitude “non-breath” EtCO2 excursions like snoring, talking, or crying, to reduce the frequency of clinically insignificant respiratory rate alarms by 53%.

Integrated Pulmonary Index™ (IPI) combines four real-time measures — EtCO2, SpO2, RR and PR — to provide an inclusive assessment of respiratory status in a single number (1-10) and promotes early awareness of changes to respiratory status.

The Apnea Sat Alert™ algorithm tracks apnea and oxygen desaturation events and calculates the associated apnea per hour (A/hr) and oxygen desaturation index (ODI) for patients.

Accurate and reliable lines

Imitation lines don’t deliver the same performance. Cross-paired sampling lines did not exhibit accurate EtCO2 readings when tested.†,1
