Etiometry Platform

Which indices are labeled for whom?

The vendor's risk analytics page lists four indices as FDA-cleared and calls them "adjunctive AI" built on "proprietary models of human physiology", without naming a machine-learning method. K254066 (April 3, 2026) is a Cardiogenic Shock Tool, listed apart from the four.

• IDO2, inadequate delivery of oxygen, gives the probability that SvO2 falls below 30, 40 or 50%. It covers post-surgical patients aged 0 to 12 years weighing at least 2 kg and adults 18 and over not on mechanical circulatory support.
• IVCO2, inadequate ventilation of carbon dioxide, gives the probability of PaCO2 above 50 or 60 mmHg in invasively ventilated patients from 0 days to 12 years.
• HLA, hyperlactatemia, gives the probability of lactate above 4 mmol/L in post-surgical patients 0 to 12 years.
• ACD, acidosis, gives the probability of pH below 7.25 in ventilated patients 0 to 12 years.

What does the platform add?

Beyond the indices, the vendor describes data aggregation and visualization, clinical pathway automation and quality improvement reporting. Its data governance page cites integration with leading EHRs including SMART on FHIR, SOC 2 and HIPAA criteria, BAAs, ISO 27001 and a CE Mark under the EU MDR. It does not name a monitor or EHR vendor. On September 10, 2026 the vendor announced a partnership with Hamilton Medical on ICU respiratory care.

What does the research show?

The vendor reports length of stay down by up to 36%, ICU readmissions down by up to 41% and ventilation time down by up to 30%, and adds that the platform "is intended to aid decision-making, not to improve outcomes independently". The homepage counts 170-plus studies enabled by the platform.

Among the papers, a 2024 JTCVS Open article validates the IDO2 index in an adult cardiovascular ICU (PMID 39780782). A 2025 Critical Care Medicine paper covers risk analytics decision support and the duration of vasoactive infusions after pediatric cardiac surgery (PMID 40298483).

Company

Etiometry, Inc. is at 770 Legacy Place, Dedham, Massachusetts. Evan Butler and Dimitar Baronov, PhD, founded it in 2010, and Shane Cooke has been president and CEO since 2019. The vendor's pages carry no funding or ownership details. Pricing is by demo request.

The verdict

A pediatric cardiac ICU wanting probabilities for post-surgical infants and children matches the labeled populations. An adult ICU has one labeled index and one adult validation paper to draw on.
