Re: New software version 4.00, new hardware and software options

Update: October 30, 2001

Reference Doc: N/A

Reason: The following product improvements are available:

· New baseline software version 4.00 (update)
The following options require installation of SW 4.n:

· Software option SW 4.n plus

· Software option mask ventilation, NIV

· Hardware option Nurse Call (Multi Function PCB)

The following hardware options require installation of SW 4.n and
hardware option Nurse Call (Multi Function PCB):

· Hardware option Evita Remote

· Hardware kit 2nd ambient pressure sensor

Solution: These are the most important changes for the operator if the device

is updated/upgraded with:

Software version 4.n (update):

- Entering the humidifier type used:
"Heated (active) humidifier" or "HME/filter" (artificial nose) for
a more accurate measurement of volume parameters.

- Apnea ventilation On/Off now selectable as a start-up
configuration.

- Extended range for the delay time "T
the range of 5 to 60 seconds (was 15 to 60 seconds).

- Additional ventilation mode "PCV+ Assist" for pressure
controlled, assisted ventilation.

- Choice of patient mode "prev. patient" for using previously
configured settings in effect before the ventilator was
switched off.

- Leak compensation On/Off

- Extended log entries, Evita 2 dura now marks alarms that

were active but not displayed with a star (*) in the log.

- Monitoring of obstructed tube with new warning message
"Tube obstruction? !!!".

Apnea", now adjustable in

- Reduction of gas consumption in standby: After 3 minutes in
Standby the control flow of 3.5 L/min and the bleed flow of

0.08 L/min is switched off by deactivating valve Y1.3. This is
an improvement especially for transport systems with battery
and gas cylinders, because the batteries can be charged in
Standby, without a slow discharge of the cylinders.

- AutoFlow: After disconnection (“Airway pressure low“ alarm)
or a detected tube obstruction AutoFlow begins with a test
stroke.

Software option SW 4.n plus (upgrade):

- Additional weaning parameters:

RSB Rapid Shallow Breathing (RSB= f

spont/VT

),
NIF Negative Inspiratory Force measures the maximum
inspiratory force of a patient during expiration hold (up to 15s)
after an expiration, and
VT P.S.: Volume, that has been applied in one pressure
support stroke.

- It is possible to output the values RSB, VT P.S. and NIF via
Medibus. You can configure these measured values in the
parameter field. RSB and VT

can be displayed as a trend.

ASB

- External flow source:
Evita 2 dura determines the contribution of external flow (e.g.
during external nubulization) and avoids flow measurement
inop alarms.

Hardware option Nurse Call:

Connection for transmitting alarm signals to a central alarm
station.

Hardware option Evita Remote:

This option consists of a remote pad with 3m (10ft) cable and a
mounting plate. Routine functions such as Alarm silence, Insp.
Hold, Exp. Hold, Start nebulizer, O2 suction and Alarm Reset are
accessible.

Hardware kit 2nd ambient pressure sensor:

This conversion kit improves operation under fast varying,
atmospheric pressure.

Software option mask ventilation, NIV:

Software option to support application of non-invasive ventilation
with a nasal or full face mask. In standby the user can choose
between tube or mask application. All ventilation modes except ILV
