CalmWave

How does the vendor say it works?

According to the vendor's transparency page, a recommendation appears only when five conditions hold. Vitals are stable, there has been no recent medication or intervention, no threshold change in the past three hours, at least three alarms in the last 15 minutes, and no outlier trends.

The vendor lists structured inputs such as vitals, staffing, EHR activity and alarm frequency and calls the output "not generative predictions", without naming the model type. It says patient data is de-identified during training and that final decisions stay with human experts. Only authorized clinical leaders approve changes, and the explanation for a recommendation can be reviewed in under 10 seconds, it says. It also describes an audit trail, a longitudinal patient record and detection of unsafe device configurations. The vendor cites "U.S. and international patents" without numbers.

What results does it report?

The homepage reports 47% fewer non-actionable alarms, 10 fewer hours of alarm exposure per patient stay and 2 to 4 nursing hours reclaimed per shift, with no methodology. A case study with Wellstar Health System is published by the vendor. No peer-reviewed study of CalmWave is known.

Company and customers

CalmWave Inc. is at 2801 Alaskan Way, Seattle, and Ophir Ronen is founder and CEO. Investor logos on the homepage include Bonfire Ventures, Tau Ventures, Rebellion Ventures and Catalyst by Wellstar, with no amounts. Catalyst by Wellstar is both an investor and part of the named customer group, which also includes Wellstar Health System and Wellstar Cobb Medical Center.

The vendor says it works with hospital middleware, monitoring platforms and EHRs from several vendors and names none. It lists SOC 2 Type II and HIPAA and claims Joint Commission alignment as a benefit. Its regulatory page makes no FDA claim, and the footer states the product "does not cure, mitigate, treat, or prevent disease". Whether it treats threshold recommendations as non-device decision support is left unsaid.

Pricing

The vendor shows no price and routes enquiries through a demo request.

The verdict

In the workflow the vendor describes, software proposes and an authorized clinical leader decides. A unit that wants that division of labor matches it, while a unit looking for a study to cite before changing limits has only the vendor's figures.
