Reason for recall

New software version for affected ventilators reduces the probability of the ventilator entering an ambient state, in which the inspiratory channel and expiratory valves are opened, letting the patient breathe room air unassisted. When the ventilator enters the ambient state, alternative ventilation must be provided immediately.

Device recalls are issued when a component, software or design fault could cause the device to fail or give wrong readings. Many are corrections applied in the field rather than physical returns.
