According to received information from our field service engineer, the personnel had forgot to secure the patient cassette by setting the patient cassette locking mechanism in locked position prior to use.This resulted in the patient cassette becoming slightly dislodged from the original position when changing the co2 absorber during ongoing surgery and thus creating a leakage.No parts needed to be replaced.There are no device logs available to confirm the reported event.Our conclusion is that the event was caused by the user not securing the patient cassette properly, i.E.User error.The leakage is detected by the system and alarms to alert the user are generated.(b)(4).
