Hamilton Medical, Inc. and Etiometry partner to advance data-driven respiratory care in the ICU. Business Wire Collaboration combines advanced ventilation technology with AI-driven clinical intelligence to support more proactive, data-driven respiratory management BOSTON, September 10, 2026-(BUSINESS WIRE)-Hamilton Medical, Inc. and Etiometry today announced a U.S. partnership to bring AI-driven, data-supported respiratory intelligence to intensive care teams managing mechanically ventilated patients. The collaboration combines Hamilton Medical's advanced ventilation technology and high-fidelity ventilator data with Etiometry's AI-powered Clinical Intelligence Platform to help clinicians transform complex, continuously generated patient data into actionable insights at the bedside. Together, the companies aim to advance respiratory care from ventilation capability to continuous, AI-supported respiratory management, helping care teams identify meaningful changes in patient condition, assess evolving respiratory needs, and make more timely and consistent clinical decisions. Hamilton Medical brings best-in-class ventilation solutions, including Adaptive Support Ventilation (ASV), which continuously adapts ventilation to a patient's respiratory mechanics. Etiometry complements these capabilities by integrating high-frequency ventilator data with other clinical and physiologic data in real time and applying advanced analytics and AI to contextualize patient trajectories and surface clinically relevant insights. These insights are designed to augment - not replace - clinical judgment. "Critical care teams are surrounded by an enormous amount of data, but the real value comes from turning that data into insights they can act on," said Shane Cooke, CEO of Etiometry. "Our partnership with Hamilton Medical brings together deep expertise in ventilation with AI-driven clinical intelligence to give care teams a more complete view of their patients, helping them review timely clinically relevant changes, support consistent use of hospital-defined protocols, and make more informed decisions. The collaboration will initially focus on key opportunities across the mechanical ventilation journey, including support for timely clinician review of hospital-defined acute respiratory distress syndrome (ARDS) and oxygenation criteria, visualization of adherence to hospital-defined lung-protective ventilation targets, and standardized clinician assessment of extubation readiness. By integrating ventilator and clinical data, the combined approach can automatically calculate key respiratory parameters - including P/F and S/F ratios, oxygenation index (OI), and oxygen saturation index (OSI) - plus display and trend them alongside ventilator settings and other clinical data. This can help care teams review changes in respiratory status, recognize deviations from hospital-defined targets, and support clinician reassessment for when intervention may be appropriate.

Hamilton Medical issues alert for breathing circuit sets after reports of valve failures. FDA has issued an early alert regarding certain coaxial breathing circuit sets manufactured by Hamilton Medical after reports of expiratory valve malfunctions that have resulted in four serious injuries. Claire Wallace, Senior Writer, Informa Markets - Engineering June 10, 2026 On May 18, Hamilton Medical sent letters to affected customers warning that certain lots of coaxial breathing circuit sets used with HAMILTON-C1, HAMILTON T-1, and HAMILTON-MR1 ventilators may not perform as intended due to expiratory valve membrane adhesion issues. According to Hamilton Medical, the expiratory valve membrane in some units adhered to the sealing ring on the body of the expiratory valve, impairing valve opening and expiratory gas flow. The issue is not detected during the standard pre-operative test of the ventilator unless a test lung is actively ventilated. When the expiratory valve membrane adheres to the sealing ring, the malfunction typically appears within the first breaths after ventilation is initiated. When expiratory gas flow is impeded, the end-expiratory pressure becomes too high or the end-expiratory flow becomes too low, triggering the ventilator's "Exhalation Obstructed" alarm. An obstruction of expiratory flow results in inadequate ventilation and impaired gas exchange. Acute respiratory compromise due to impaired exhalation may result in inadequate ventilation and oxygen desaturation, also known as hypoxemia. As of May 13, Hamilton Medical reported four serious injuries and no deaths associated with this issue. The affected devices include: T1 CIRCUIT 240 +VALVE B/10 (Product Number: 260127) T1 CIRCUIT 180 +VALVE B/20 (Product Number: 260128) MR1 CIRCUIT 300 +VALVE B/10 (Product Number: 260167) MR1 CIRCUIT 480 +VALVE B/8 (Product Number: 260168) All affected products are Hamilton Breathing circuit sets, coaxial, preassembled with an expiratory valve set. Hamilton Medical is recommending that users verify unimpeded expiratory gas flow prior to use by ventilating a test lung using specific settings provided by the company after performing the pre-operative test. "If no 'exhalation obstruction' alarm is issued, the expiratory valve is safe to use," the company stated in its customer letter. "If the 'exhalation obstruction' alarm is triggered, do not use the coaxial breathing circuit set. The coaxial breathing circuit set must be discarded and replaced." If the "Exhalation Obstructed" alarm is triggered during patient use, Hamilton Medical recommends users disconnect the patient from the ventilator and ensure alternative means of ventilation, such as an alternative ventilator or hand bagging. Healthcare facilities are advised to inform all potential users of affected coaxial breathing circuit sets about this issue and post the provided notice. Affected products may continue to be used with the risk mitigations provided. Hamilton Medical ventilator coaxial breathing circuits are intended to connect HAMILTON-C1/T1/MR1 ventilators to a patient tube or respiratory mask during ventilation. FDA stated it is currently reviewing information about this potentially high-risk device issue and will keep the public informed as significant new information becomes available. In August, Hamilton Medical AG issued a correction for HAMILTON-C6 ventilators due to a risk of ventilation interruption from defective circuit boards, but no deaths or injuries were reported. Hamilton has been relatively free of recalls the last several years, but in 2024, the company corrected software for its Hamilton-C6 ventilator after one reported injury and one report of death. At the end of 2023, the company recalled its Hamilton C1/T1/MR-1 ventilators after degrading capacitors on the control board and spare parts leaked electrolyte fluid onto the control board, potentially causing a short circuit, and recalled its C1, C2, C3, and T1 ventilators with the neonatal option installed following software issues that could cause the machines to stop ventilating without notice.
