Intended Medical Application
Intended Medical Application
Long-term ventilator for intensive care.
For adults, children and neonates.
For premature babies with the "NeoFlow" option.
With the following ventilation modes:
IPPV Intermittent Positive Pressure Ventilation,
controlled and assisted constant-volume ventilation.
With the options:
– CPPV (Continuous Positive Pressure Ventilation)
– PLV (Pressure Limited Ventilation)
®
– AutoFlow
for automatic regulation of inspiration flow
– IRV (Inversed Ratio Ventilation)
SIMV Synchronized Intermittent Mandatory Ventilation,
procedure for weaning patients off the ventilator after
they have started spontaneous breathing.
With the options:
– PLV (Pressure Limited Ventilation)
®
– AutoFlow
for automatic regulation of inspiration flow.
MMV Mandatory Minute Volume Ventilation,
spontaneous breathing with automatic adjustment of
mandatory ventilation to the patient's minute volume
requirement.
With the options:
– PLV (Pressure Limited Ventilation)
®
– AutoFlow
for automatic regulation of inspiration flow.
SB Spontaneous Breathing,
Spontaneous breathing at ambient pressure.
CPAP Continuous Positive Airway Pressure,
Spontaneous breathing with positive airway pressure.
ASB Assisted Spontaneous Breathing,
pressure-assisted spontaneous breathing.
BIPAP* Biphasic Positive Airway Pressure,
Pressure-controlled ventilation combined with free
spontaneous breathing during the complete breathing
cycle, and adjustable pressure increase to CPAP level.

BIPAP (Biphasic Positive Airway Pressure Assisted)
Assist
Pressure-controlled assisted ventilation
APRV Airway Pressure Release Ventilation,
Spontaneous breathing on two pressure levels with long
time ranges – independently adjustable.
Special modes:
Apnoea Ventilation
For switching over automatically to
volume-controlled mandatory ventilation, if breathing
stops.
If apnoea occurs, Evita 4 emits an alarm after the preset
alarm period (T > ) and starts volume-controlled
Apnoea
ventilation.
ILV Independent Lung Ventilation,
Separate, differentiated, synchronised ventilation with
two Evita units, one for each lung.
Diagnostics:
Intrinsic PEEP-measurement
for determining intrinsic PEEP and measuring trapped
volume.
Occlusion pressure measurement
for evaluating breathing drive during spontaneous
breathing.
With monitoring for:
airway pressure, Paw
expiratory minute volume, MV
inspiratory O concentration, FiO
2
inspiratory breathing gas temperature, T
expiratory CO concentration, etCO
2
inspiratory breathing volume, V
apnoea time
tachypnoea monitoring to detect rapid, shallow
spontaneous breathing
Automatic gas switch-over.
In the event of a gas failure, the change-over to another
gas is automatic.
