Smart Capnography™: Integrated Pulmonary Index™ (IPI)
Smart Capnography™ Algorithms Clinical Validation
The Integrated Pulmonary Index™ (IPI) algorithm incorporates etCO2, respiratory rate, SpO2 and pulse rate into a single number that represents an inclusive respiratory profile. This algorithm has been clinically validated against patient status assessments of a group of medical professionals.
The results of the IPI™ model showed strong correlation in multiple clinical studies, and have led to these conclusions:
- IPI™ correlates with respiratory status.
- The single numeric value of IPI™ may be particularly valuable for promoting early awareness of respiratory distress.
- IPI™ simplifies the monitoring of patients in busy clinical environments.

Smart Capnography™: Smart Alarm for Respiratory Analysis™ (SARA)
In clinical studies, the Smart Alarm for Respiratory Analysis™ (SARA) algorithm was shown to recognize and reduce clinically insignificant respiratory alarms, while accurately reflecting the patient’s condition and preserving clinically significant alarm vigilance.
