Certainty when it matters most

From procedural sedation to general care floor, reliable access to respiratory status is vital to providing comprehensive care. The Capnostream™ 35 portable respiratory monitor delivers real-time, continuous monitoring of your patient’s respiratory status by measuring etCO2, SpO2, respiration rate, and pulse rate. The Capnostream™ 35 monitor is designed for monitoring in virtually any clinical setting.

The Capnostream™ 35 portable respiratory monitor offers you comprehensive respiratory monitoring to help you respond earlier and intervene sooner if your patient is showing signs of respiratory compromise. The monitor provides information to help support clinical decisions and may improve workflow.


  • Continuous, non-invasive, real-time respiratory status monitoring of etCO2, SpO2, respiration rate, and pulse rate.
  • May help increase opportunities for clinicians to identify respiratory events earlier and intervene sooner when monitoring patients on the general care floor, in the emergency department and recovery room , during procedural sedation and during intra-hospital and prehospital transport.
  • Intended for use with patients of any age; adult, paediatric, infant to neonate; intubated to non-intubated, with sampling lines specifically developed for patient type and use case.
  • Rugged, lightweight, shockproof, ergonomic design that’s as functional in the hospital setting as it is in air and ground transport.

Smart Algorithms and Smart Alarm Capabilities:

  • The Integrated Pulmonary Index™ algorithm combines four real-time measures: etCO2, SpO2, respiratory rate and pulse rate, to provide an inclusive assessment of a patient’s respiratory status in a single number.
  • Apnea-Sat Alert™ algorithm provides actionable insight to potentially prevent adverse respiratory events with summary reports of recurring apnea events per hour as well as oxygen desaturations.
  • Smart alarm management technology may reduce clinically insignificant respiratory alarms and provides a clearer indication of patient status while preserving alarm vigilance. Smart alarm technology includes Nellcor™ pulse oximetry SatSeconds™ alarm management and Smart Alarm for Respiratory Analysis™ algorithm (SARA).

Data Management Capabilities:

  • Patient data can be sent wirelessly to the Vital Sync™ virtual patient monitoring platform, providing the flexibility to view patient information on any web enabled device, EMR or Clinical Information System.
  • Patient data can be stored on USB drive or SD Card, printed, and transferred to other data systems.

Proven Performance in Critical Situations([FOOTNOTE=American Heart Association (AHA), Highlights of the 2015 American Heart Association Guidelines Update for CPR and ECC, 2015.],[ANCHOR=],[LINK=])

Waveform capnography enables monitoring of CPR quality, chest compressions, ROSC, and correct placement of endotracheal tube. Capnography monitoring in transport can reduce the risk of unrecognised tube displacement.

Sepsis, severe sepsis, and septic shock are a common cause of hospital death with high costs to healthcare. Rapid identification and intervention increase survival and improve economic outcomes. Evidence suggests capnography may provide a comparable assessment to lactic acid levels.
