Smart Capnography™

Smart Capnography™ is a family of algorithms developed by Oridion that can reduce clinically insignificant alarms^* and provide clinical utility for improved patient safety.

Today, Smart Capnography includes Smart Breath Detection Algorithm™ (BDA™), Smart Alarm Respiratory Analysis ™ (SARA), and the Integrated Pulmonary Index™ (IPI). Smart Capnography can be found only in Microstream Capnography equipped patient monitors, such as the Oridion Capnostream® 20.

^* a clinically insignificant alarm is defined as a respiration rate alarm lasting continuously for less than 30 seconds or less than 45 seconds over a period of 60 seconds when compared to the previous respiration rate algorithm

Smart Breath Detection Algorithm™ (BDA)

The Smart BDA suite of proprietary filter and pattern recognition algorithms screens out low amplitude etCO₂ changes superimposed on the etCO₂ waveform. The result is that Smart BDA focuses on actual breaths, rejecting shallow, non-breath etCO₂ excursions.

Smart Alarm Respiratory Analysis™ (SARA)

SARA™ is an alarm management technology that recognizes and reduces respiratory rate nuisance alarms while accurately reflecting the patient’s condition and preserving caregiver alarm vigilance. Preserving caregiver vigilance to alarms is essential for patient safety. ¹

Virtually every patient connected monitor uses audible alarms to notify caregivers of a change in patient condition or in device status. However, numerous alarms that do not indicate clinically significant issues a distraction to busy caregivers. Reducing distractions from clinically insignificant alarms^* helps preserve caregiver alarm vigilance, leading to improved patient safety.

Integrated Pulmonary Index™ (IPI)

IPI utilizes etCO₂, respiration rate, pulse rate and SpO₂ to provide an uncomplicated, inclusive assessment of a patient’s ventilatory and oxygenation status. By following the trend of the IPI, a clinician can quickly assess the inter-relations of a patient’s respiratory parameters.

IPI also provides an early indication of changes in a patient’s respiratory status that may not be indicated by the values of the individual parameters.³,⁴
