User Manual
All the physiological alarms of the Vivo 3 must be set at safe levels that will effec-
tively warn the user of any risk.
The alarm levels should be assessed considering the patient's treatment settings.
Any change of treatment settings or change of components in the ventilation sys-
tem may require readjustment of the alarm levels.
The alarm sound level should be set to a clearly audible level. Setting the alarm
sound level below that of the ambient sound level can impede recognition of alarm
conditions.
