Medical Equipment Crashes During Heart Procedure Because Of Antivirus Scan (softpedia.com)
An anonymous reader quotes a report from Softpedia: The device in question is Merge Hemo, a complex medical equipment used to supervise heart catheterization procedures, during which doctors insert a catheter inside blood veins and arteries in order to diagnose various types of heart diseases. According to one such report filed by Merge Healthcare in February, Merge Hemo suffered a mysterious crash right in the middle of a heart procedure when the screen went black and doctors had to reboot their computer. Merge investigated the issue and later reported to the FDA that the problem occurred because of the antivirus software running on the doctors' computer. The antivirus was configured to scan for viruses every hour, and the scan started right in the middle of the procedure. Merge says the antivirus froze access to crucial data acquired during the heart catheterization. Unable to access real-time data, the app crashed spectacularly.

Based upon the available information, the cause for the reported event was due to the customer not following instructions concerning the installation of anti-virus software; therefore, there is no indication that the reported event was related to product malfunction or defect. The product security recommendations, (b)(4), explicitly state, "the intent of these guidelines is to configure the anti-virus software so that it does not affect clinical performance and uptime while still being effective. To accomplish this, the anti-virus software needs to be configured to scan only the potentially vulnerable files on the system, while skipping the medical images and patient data files. Our experience has shown that improper configuration of anti-virus software can have adverse affects including downtime and clinically unusable performance. ".
The device was hooked via a serial cable to a PC to record the logs during the procedure. The PC antivirus ran, and locked the log file to scan it, causing the medical device to crash. Yes, that is a very bad way to design a machine.
The machine didn't use Windows. It was hooked to a PC to record the logs during the procedure so the doctor could review them later. The AV software locked the log to perform the scan, and the medical device crashed. They had to reboot the PC to keep working.
