IVCO2 Index™

The IVCO2 Index™ provides a continuous risk estimation of inadequate ventilation or hypercapnia. The Index uses mathematical models of human physiology to determine the likelihood that the patient is experiencing inadequate carbon dioxide ventilation. The algorithm also estimates the mismatch between lung ventilation and perfusion, accounting for differences that can occur between EtCO2 values and arterial CO2 levels measured via an arterial blood gas sample.

  • Calculated using clinical data automatically collected by the T3 Software
  • Continuously updated and displayed in a numeric and trend format
  • Requires no additional data entry by clinicians

The IVCO2 Index™ is derived using key vital signs and laboratory results collected by the T3 Software.

The IVCO2 Index™ and relevant patient parameter trends are displayed on one screen.

Etiometry’s IVCO2 Index™ is solely indicated for use for invasively mechanically ventilated patients 0 days to 12 years with weights above 2 kg.
The solution is being provided under FDA’s enforcement policy for non-invasive remote monitoring devices used to support patient monitoring during the coronavirus disease 2019 (COVID-19) public health emergency.
The Etiometry Platform is not an active patient monitoring system. It is intended to supplement and not replace any part of the hospital’s device monitoring. Do not rely on the Etiometry Platform as the sole source of patient status information. For prescription use only.
