The only integrated, complete picture of oxygenation and ventilation([FOOTNOTE=Maddox RR, Oglesby H, Williams CK, Fields M, Danello S., Continuous respiratory monitoring and a “smart” infusion system improve safety of patient-controlled analgesia in the postoperative period. http://www.ahrq.gov/downloads/pub/advances2/vol4/Advances-Maddox_111.pdf ],[ANCHOR=View Abstract],[LINK=/content/covidien/websites/medtronic/com/en/covidien/support/clinical-evidence.html?id=573452])

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 ([FOOTNOTE=ECRI Institute. The Hazards of Alarm Overload: Keeping Excessive Physiologic Monitoring Alarms from Impeding Care. ECRI Guidance Article, March 2007.],[ANCHOR=],[LINK=]),([FOOTNOTE=Hockman S, Glembot T, Niebel K.

  • 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.
