!!! Flow measurement inop. Water in flow sensor. Dry flow sensor.
Flow sensor faulty. Replace flow sensor.
Flow measurement malfunction. In order to continue ventilating with
Savina:
Use alternative external flow monitoring
and switch off the built-in flow monitoring,
page 50.
Call DrägerService.
! Flow monitoring off Flow monitoring is switched off. Switch flow monitoring on again, see
page 50, or immediately provide
adequate external monitoring.
!!! Flow sensor? Flow sensor not fully inserted in
rubber lip of expiration valve.
Insert flow sensor correctly.
!!! High frequency Patient is breathing at a high
spontaneous frequency, therefore the
monitored overall frequency is too high.
Check condition of patient.
Check pattern of ventilation.
Correct alarm limit if necessary.
!!! Insp / Exp cycle failure The device does not deliver any gas. Set an IPPV frequency of at least 4/min.
Apnoea alarm time TApnoea is set
less than time for one respiration phase
