React Health Issued Alert for VOCSN Ventilator Devices
Patients and caregivers should use backup ventilation if their device triggers a System Fault 10 alarm.
Updated on Sept. 23, 2026 in Asthma
React Health has issued an early alert for all configurations of its VOCSN ventilator devices due to a potential recurring reboot issue. No injuries or deaths have been reported to date, and the manufacturer has notified affected customers.
Why it matters
This alert ensures that users and caregivers remain vigilant about device performance, as unseated internal cables can interrupt the ventilation system. While no reboots have occurred during active therapy, maintaining access to backup support remains a critical safety step.
This early alert follows reports of recurring reboots and System Fault 10 alarms across all VOCSN configurations. As of August 12, 2026, there have been no confirmed instances of the reboot occurring while a patient was receiving active therapy.
The players
React Health
A medical device company that manufactures ventilators and other respiratory care equipment.
Food and Drug Administration
The federal agency responsible for regulating medical devices and overseeing public health safety alerts.
The details
The reboots are caused by the internal flow transducer cable connector becoming partially or fully unseated, often due to substantial impacts to the device. This disconnection causes a loss of communication with the transducer board, which triggers a System Fault 10 alarm and forces the device to reboot.
Timeline
August 12, 2026: No injuries or deaths were reported by this date.
September 17, 2026: React Health issued notification letters to affected customers.
Health Landscape
This alert operates within the established safety monitoring protocols managed by the Food and Drug Administration to track medical device performance. It ensures that clinicians and patients are informed of hardware risks in real-time to maintain continuity of care.
If you or a loved one uses a VOCSN ventilator, ensure you have your backup ventilation device ready and easily accessible. Contact your healthcare provider immediately if your device experiences a System Fault 10 alarm or unexpected reboots.
The takeaway
Reliable access to backup ventilation is essential for all users of mechanical support devices. Always follow the manufacturer's guidance regarding system alarms and discuss any hardware concerns with your clinical team during your next check-in.
