Stryker has initiated a field action to prevent its LifePak 15 defibrillator-monitor systems from locking up after delivering a shock to a patient.
February 4, 2019 — Stryker announced Feb. 1, the company is launching a voluntary field action on specific units of the LifePak 15 Monitor/Defibrillators. The company is notifying certain customers of an issue that may cause the device to lock up after a defibrillation shock is delivered.
The lock-up condition is defined as a blank monitor display with LED lights on, indicating power to the device, but no response in the keypad and device functions. A device in this condition has the potential to delay delivery of therapy, and this delay in therapy has the potential to result in serious injury or death.
The company is contacting customers with impacted devices to schedule the correction of their device(s), which will include an update to the firmware for a component on the system printed circuit board assembly. Stryker anticipates that all devices subject to this field action will be serviced by Dec. 31, 2019.
Since the initial commercialization of LifePak 15 in 2009, Stryker has become aware of 58 complaints reported globally for this issue, including six events in which the patient died following a delay in therapy. In all six of these cases, at least one shock was delivered prior to the device experiencing the lock-up condition. There are 13,003 devices potentially impacted by this issue and within scope of this field action.
The company is instructing customers to continue to use their LifePak 15 devices according to the operating instructions until the correction can be completed. The company said the device automatic self-tests do not identify this fault, as it occurs during defibrillation. Customers should continue to perform the daily check as described in the operator’s checklist, specifically, the Quik-Combo therapy cable check as described in the general maintenance and testing section (pages 10-4 and the LifePak 15 Monitor/Defibrillator Operator’s Checklist, number 7).
What to Do if the LifePak 15 Locks Up After a Shock?
If a device exhibits the lockup condition during patient use, the steps from the general troubleshooting section (page 10-18) of the operating instructions should be immediately followed:
1. Press and hold ON until the LED turns off (about 5 seconds).
2. Then press ON to turn the device back on.
3. If the device does not turn off, remove both batteries and disconnect the device from the power adapter, if applicable. Then reinsert batteries and/or, reconnect the power adapter, and press ON to turn the device back on.
