React Health Issued Alert For VOCSN Ventilators
The company warned that specific ventilator configurations may experience recurring reboots and system alarms.
Updated on Sept. 23, 2026 in Asthma
React Health has issued an early alert for all configurations of its VOCSN ventilator devices due to potential recurring reboots and System Fault 10 alarms. No injuries or deaths have been linked to this issue as of August 12, 2026.
Why it matters
The alert ensures that users and healthcare providers are aware of a hardware issue where internal cables may unseat, potentially disrupting therapy. Recognizing the signs early allows patients to transition to backup ventilation systems, preventing life-threatening interruptions in support.
The alert pertains to all VOCSN ventilator models, which are cleared for use by patients weighing at least 5 kg. These units are identified by the System Fault 10 alarm, which signals a loss of communication with the internal flow transducer board.

The details
The malfunctions occur when a cable connector inside the device becomes partially or fully unseated, a process often triggered by substantial physical impacts to the unit. While there have been no reported instances of devices rebooting during active therapy sessions, the hardware fault causes a complete loss of communication with the internal flow transducer board.

The Big Picture
This notification follows the standard procedural framework established by the FDA for alerting the public to potential equipment malfunctions. The alert is part of the FDA medical device recall and early alert reporting process designed to mitigate risks before device failure results in patient harm.
Patients using VOCSN ventilators should inspect their devices for any signs of the System Fault 10 alarm and ensure they have a backup ventilation system ready for use. If you experience recurring reboots, contact your healthcare provider immediately to discuss your care plan.
The takeaway
Users of medical equipment should always maintain a secondary plan for equipment failure to ensure continuous therapy. If your device displays recurring system faults, prioritize safety by switching to your backup unit while consulting with a medical professional.
