What the authority reported
If ultrasound systems with software, are changed from factory default to : 1) Milliliters per second (ml/sec, mL/sec) or 2) Milliliters per minute (ml/min, mL/min); then systems will perform incorrect unit conversion of liters to milliliters using multiplier 100 instead of 1000, resulting values 10x smaller than actual, which could contribute misdiagnosis or negatively influence patient management
What to do
Follow the instructions in the official notice — recall remedies (refund, repair, replacement, or disposal) are defined by the issuing authority and the responsible business, and they differ per recall. Do not rely on summaries, including this one.
