German medical device manufacturer Dräger has voluntarily recalled the optional PS500 Power Supply Unit used with the Evita V500 and Babylog VN500 ventilators following complaints that the battery drained quicker than expected even though the battery icon still showed a charged battery.
An investigation revealed the expedited battery drainage was caused by sulfation in the battery.
No reports of patient harm have been indicated, but if the battery completely drains, the ventilator will stop working.
Dräger is providing interim battery replacements free of charge to customers. Additionally, the company is developing a permanent battery replacement, which will also be provided free of charge once it becomes available.
