Maquet Servo Ventilators in Class 1 Recall
Maquet Critical Care AB, a subsidiary of Getinge, is recalling (Class 1 device correction) its Servo Ventilator Systems to update their use instructions due to the risk of inaccurate compliance measurement leading to improper tidal volume delivery in neonatal patients. The devices can be used with several different patient circuits and active humidifiers.
“Before being used on a patient, the ventilator must pass a safety check that measures leakage, compliance, and resistance in the circuit,” a recall notice says. “Some humidifiers may not pass the standard leak test due to their design, even if there’s no actual leak. To address this, there is an optional configuration for the ventilator with an ‘extended leakage test’ in the ventilator’s Service & Settings menu.” This extended test should only be used with humidifiers that cannot pass the standard leak test, the notice says, adding that if a hospital uses multiple humidifier types, there’s a risk that the ventilator could be set to the wrong test for the humidifier being used.
