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.
*Registered trade mark
BIPAPAssist (Biphasic Positive Airway Pressure Assisted)
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 (TApnoea >) and starts volume-controlled ventilation.
ILV (Independent Lung Ventilation)
Separate, differentiated, synchronised ventilation with two
Evita units.
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 O2concentration, FiO2
inspiratory breathing gas temperature, T
expiratory CO2concentration, etCO2
inspiratory breathing volume, VTi
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.
