Core clinical engineering and protocols for Fail-Open Clinical Safety.
In medical device engineering, patient safety always supersedes cybersecurity: a cybersecurity system that interrupts ventilator telemetry or arterial line alarms during a crash can cause immediate patient death.
IoMTWall utilizes solid-state optical relays governed by an isolated hardware watchdog circuit. If the firewall software encounters a kernel panic or power loss, the relays instantly de-energize into passive optical pass-through mode, ensuring unhindered transmission of vital signs.
