Contrary to the information as provided initially, the affected device was an infinity acs workstation cc (evita v500) with a c500 cockpit.The affected c500 cockpit was returned to the manufacturer's repair workshop for examination.The reported display malfunction could be reproduced.The ccfl tubes (fluorescent tubes) of the cockpit were faulty and caused an impaired display illumination.Due to the limited visibility of the display content, the operability of the ventilator by the user may be impaired.The display was completely replaced.Ventilation is not affected by a malfunction of the cockpit display and continues as set.Safety-relevant parameters such as fio2, minute volume or airway pressure are shown on the secondary oled display of the ventilator and the user can monitor the ongoing ventilation.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
