It was reported that the ventilator experienced leakage due to leak in the air hose.The service engineer found a loose air connection.Readjustment of the wall air intake to hose connection solved the problem.No picture showing the problem was received.No part was replaced.This concerns the air gas supply outside the ventilator.The gas supply pressure is checked during pre-use check.If the air gas supply is reduced during ventilation, insufficient ventilation may follow.Alarms will be raised if set alarm limits are violated.The conclusion is that the service engineer readjusted the wall air connection, which resolved the problem.No technical ventilator malfunction was found.
