CalmWave offers the Quiet ICU via an Operations Platform that uses "Transparent AI" to make its reasoning and data visible and to recommend optimized alarm settings at the bedside. The platform ingests retrospective and real-time patient data — vital signs, interventions, and medication administration — to generate objective recommendations to reduce alarm fatigue. CalmWave reports a 58% reduction in non-actionable alarms in a retrospective analysis of a charter customer’s Cardiac Care unit. The company cites that 80–99% of ICU alarms are non-actionable and positions its product as a solution to improve clinician workload, patient outcomes, and staff retention. CalmWave operates as a SaaS platform and is expanding channel partnerships with GPOs such as Premier, Inc. and Partners Coop. The company will use new capital to accelerate market penetration and grow both new and existing channel partnerships. CalmWave provides a platform that ingests data from all devices a patient is connected to and delivers customizable views for clinicians, including individual patient views, ward summaries, and clustered patient alarms. Its platform produces “Operations Health Scores” that describe each nurse’s workload and well-being using factors such as alarm volume, response times, patient length of stay, and nurse-to-patient ratio. Key features include Smart Alarms that group alerts into incidents, Device Thresholds and Alarm Monitoring, Intelligent Patient Acuity scoring, Staff Orchestration to balance workloads and improve retention, Insights & Analytics for users across roles, and built-in Expert Services for assessment and implementation. The company is led by CEO and Founder Ophir Ronen. CalmWave says it will use the funds to recruit talent, advance new marketing initiatives, and create and launch innovative products. The product and roadmap are focused on reducing alarm burden, optimizing staffing, and improving patient outcomes through data-driven operational insights.
