Figure for Capnostream 20 Bedside Patient Monitor for Capnography for RMS

The only integrated, complete picture of oxygenation and ventilation1

The Capnostream™ 20p patient monitor is built on a legacy of proven performance. For nearly two decades, clinicians have relied on Microstream™ technology for an accurate, continuous view of ventilation adequacy on intubated and non-intubated patients, from neonate to adult. The new Capnostream 20p monitor, with the Apnea-Sat Alert feature, alerts caregivers to repetitive patterns of apneas and oxygen desaturation, revealing a more complete picture of a patient’s respiratory status.

Capnostream™ 20p Bedside Patient Monitor Features

Dual parameter monitor

  • - Supports current standards of care by providing etCO2 and SpO2 measurements.

Smart Alarm Management™ Integrated Algorithms 1-2

- The Capnostream™ 20p patient monitor with Microstream™ includes Smart Alarm Management™ Integrated Algorithms, a suite of algorithms proven to reduce alarms and simplify the use of patient monitoring to enhance patient safety and improve clinical efficiency.

Smart Breath Detection™

  • - Screens out low amplitude ‘non-breath’ etCO2 excursions like, talking, crying or snoring.

Smart Alarm for Respiratory Analysis™ (SARA)

  • - Reduces clinically insignificant alarms.

Nellcor™ SatSeconds

  • - Alerts clinicians to clinically significant changes in pulse oximetry.

Integrated Pulmonary Index™ Algorithm (IPI )

  • - IPI algorithm presents one value that demonstrates real-time respiratory status based on etCO2, RR, PR and SpO2.††

Apnea-Sat Alert™ Algorithm (ASA ) †††

  • - Tracks and reports apneas per hour and oxygen desaturation index, and provides the data in trend reports.


  • - Compatible with central monitoring systems and interfaces with nurse call systems and electronic medical records.

Internal printer

  • - Provides convenient bedside documentation.

SARA evaluates the stability of the detected breath-to-breath intervals and adjusts (adapts) the measurement period accordingly, thus averaging out noise and transient fluctuations when required, providing a more realistic respiratory rate.

††SpO2 data from host required.

†††Apnea-Sat Alert is FDA cleared for adults 22 years of age or older.
