Function description
General information The Savina is a long-term ventilator unit designed for patients with a tidal vol-
ume of 50 mL and above, and for the following applications:
– Intensive care unit,
– Recovery room,
– Secondary transportation from hospital to hospital,
– Patient transfer within the hospital,
– Transfer flights.
Functional principle The Savina generates the compressed air for ventilation with a blower, which
means the Savina is able to ventilate without any connection of compressed
air or oxygen. A controllable valve is switched in parallel with the blower to
regulate the pre-set ventilation parameters. The valve opens or closes
according to the pre-set ventilation parameters.
To increase the oxygen concentration in the ventilatory gas, an oxygen concentrator, e.g. a Permox SilentCare, can be connected. If compressed oxygen is connected to the Savina, the oxygen concentration of the ventilating
gas can be precisely metered. The oxygen concentration is then metered
internally with sensors, the associated electronics, and a bank of valves.
Monitoring The Savina has the following monitoring system:

Power supply unit The power supply unit delivers the supply voltages for the Savina. The input
voltage range of the power supply unit is 100 V to 240 V AC and 50 Hz to 60
Hz. However, the power supply unit can also be operated with an external
rechargeable battery (12 V or 24 V) or with an external on-board - ambulance/helicopter - power supply (10.5 V to 36 V).
The connection for the alternating voltage is made by a power cable. The
connection for the external rechargeable battery or the external on-board
power supply is made by a coded plug.
The power supply unit actuates the three „Mains power“, „External battery or
on-board power supply“ and „Internal battery“ LEDs. The LEDs are mounted
on the keypad of the control panel, and indicate the current operating status.
The Savina includes 2 internal rechargeable batteries (2 x 12 V) which
enable uninterrupted operation in the event of a complete failure of external
power. The internal rechargeable batteries supply the O2 sensors with power,
even when the Savina is switched off. As a result, valid O2 values are available immediately on power-up.
The power supply unit supplies the following output voltages:
–+5V
–-15V
–+15V
–+24V
–+48V
The output voltages are short-circuit-proof and stable at no-load.
The output voltages are generated according to the following priority, dependent on the input voltages:
Input voltage Priority Action

Control PCB The Control PCB is the central „control and monitoring unit“ of the Savina. It
has two separate processor systems (the master and front processors).
The program memories are flash EPROMs. The flash EPROMs can be programmed with a laptop connected to the serial port of the Savina (software
download).
An EEPROM is provided for each processor system for storage of changeable, non-volatile data.
The calibration data of the sensors, fans etc. are stored by the master's
EEPROM.
The EEPROM of the front processor stores the software options, device IDs,
safety parameters and settings such as contrast, volume etc., as well as a
„backup copy“ of the operating hours reading. The EEPROM of the front processor is plugged in and, if the board needs to be replaced, must be mounted
on the new board.
The real-time clock generates the time and date information. The real-time
clock has an internal battery.
The Control PCB contains the following functions:
– Processing of the signals from the sensors (O2, flow, pressure, tempera-
ture),
– Control of the blower and valves
– Monitoring of the unit functions and the supply voltages
– Actuation of the displays,
– Keypad interpretation,
– Provision of the internal and external interfaces

Motor actuator The motor actuator controls the blower motor. The motor actuator is located
in a self-contained housing. The supply voltage for the motor actuator is +48
V and is protected by a fuse (6.3AT).
The input voltage range of the motor actuator is 12 to 52.5 V. The rotation
speed is set by the Control PCB. The control voltage for the rotation speed is
0 V to +5.00 V, corresponding to a rotation speed of 0 to 12,000 rpm. The
rotation speed range is 4,000 to 12,000 rpm.
The motor actuator delivers the „actual speed signal“ and forwards it to the
Control PCB. The „actual value signal“ is 6 pulses per rotation. In the event of
discrepancies in the rotation speed the Control PCB adjusts the speed
according to the deviation.

O2 Valve PCB The O2 Valve PCB holds the pressure sensors (absolute pressure S6 and S7
and O2 supply pressure S5), the actuator for the O2 calibrating valve and the
nebulizer valve and the actuator for the valve block.
The signals of the pressure sensors are amplified and routed to the Control
PCB. The supply voltage (+5 V) for the pressure sensors is generated by the
O2 Valve PCB.
The valve block valves, the O2 calibrating valve and the nebulizer valve can
be operated separately by an electronic switch. They are actuated by the
Control PCB.
Fig. 5 Block diagram of the O2 Valve PCB
O2 Diaphragm PCB The O2 Diaphragm PCB amplifies the signals from the O2 sensors and mea-
sures the temperature of the O2 sensors and of the respiratory gas in the
inspiration block. The temperature of the O2 sensors is required to compensate for the temperature-sensitive O2 measurements. The calibration data
from the sensors are stored on the Control PCB in an EEPROM. The reference voltage for the O2 sensors is generated from the voltage of the
rechargeable batteries.
The supply voltages for the O2 Diaphragm PCB are +5 V and +15 V.

The following description details the functions of the main components.
chamber. The blower compresses the gas to a positive pressure of max.140
mbar at a flow rate of up to 180 L/min. The blower is run at constant rotation
speed - that is, the speed is not varied in the course of a breath. The inspiratory pressure is regulated by means of the bypass valve. The combination of
the blower and the bypass valve function thus represents a pressure source.
Fig. 13 Detail view of functional diagram; ventilation function
On the inlet and outlet sides of the blower there are mufflers SD1 and SD2,
which reduce the sound level of the blower.
The bypass valve V1 is operated such that the desired respiratory pressure is
applied to the blower outlet, and thus to the patient. In the inspiratory phase
when a high flow rate is required by the patient, part or all of the gas flows
from the blower outlet to the patient; the gas flow in the return line is reduced.
In the expiratory phase the entirety of the blower gas flows via the return line.
A cooler reduces the respiratory gas temperature down to a permissible
range. A fan blows cooling air onto the surface of the cooler to dissipate the
heat from the cooler.
Expiration occurs via a directly operated valve V3.
The expiratory valve has two functions:
– Controls the PEEP during expiration
– Closes the breathing system during inspiration

O2 mixture with high pressure
In order to be able to ventilate with an increased O2 concentration, the unit
must be supplied with 2.7 to 6.0 bar O2. O2 is filtered via the intake filter F2.
With the aid of a digital valve bank consisting of 8 digital solenoid valves, O2
is metered into a volume (mixing chamber). The amount of metered O2
depends on the pre-set O2 concentration and on the inspiratory flow rate
measured by the flow sensor S1. The addition of O2 is regulated in a closed
loop. In the process, the inspiratory O2 concentration is measured by the O2
sensor S 3.1.

Function descriptions
Pneumatic assembly
CAUTION
Connect only O2 low pressure sources without humidifier to the Savina!
An O2 low pressure source without humidifier feeds the oxygen into the
„LPO“ connection on the back of the unit. The filter (filter element) F5 protects
the non-return valve D6 from coarse particles. The oxygen flows from the
non-return valve D6 into the volume (mixing chamber). In the volume (mixing
chamber) it is mixed with the drawn-in and filtered fresh air.
Fig. 15 Detail view of functional diagram; O2 mixture with O2 low pressure
When no O2 low pressure source is connected to the unit, the non-return
valve D6 prevents gas from escaping during normal operation.

Pneumatic safety devices The independent pneumatic safety valve D1 ensures that the ventilation pres-
sure can never rise above the legally prescribed limit of 120 mbar. In the
event of inspiratory stenosis the pressure is limited by opening the expiratory
valve. The mechanical negative-pressure valve D2 ensures (except in the
case of inspiratory stenosis) that the patient can breathe spontaneously from
the ambient air in case of a fault.
The emergency vent valve V9 relieves the pressure in the breathing system
in a case of expiratory stenosis if the pressure cannot be relieved through the
expiratory valve. The pilot valve V8 operates the emergency vent valve V9.

Drug nebulizer The drug nebulizer is operated with 100% O2. The supply pressure regulator
DR1 ensures, with widely varying supply pressure (2.7 to 6.0 bar), that the
pneumatic drug nebulizer receives a constant supply pressure of 2.0 bar.
When the nebulizer function is active the solenoid valve V5 operates in an
„inspiration“ (open position) and „expiration“ (closed position) cycle. When
the nebulizer function is inactive valve V5 is permanently closed.

Pneumatic assembly
O2 calibration function In normal operation of the unit the solenoid valve V4 is set to „measurement“
- that is, the connection between the inspiration and the oxygen sensor is
open. During O2 sensor balancing it opens the way for the oxygen to the sensor. This layout permits online calibration of sensor S3.1 during ventilation.
Sensor S3.2 must be calibrated manually (patient disconnected).
Fig. 18 Detail view of functional diagram; O2 calibration function
O2 sensor detection The unit is provided with an O2 sensor detection. The O2 sensor detection is
not required for the optional „LPO“.

Sensors The absolute pressure sensor S6 delivers the measured atmospheric pres-
sure value required for O2 measurement and for volume application. Absolute pressure sensor S7 monitors sensor S6. Sensor S3.1 delivers the signal
for the displayed value FiO2 and the signal for control of the inspiratory O2
concentration. Sensor S3.2 monitors sensor S3.1.

measured on the basis of the measured value from the pressure sensor in
the respective no-flow branch. Pressure sensor S4.3 continuously measures
the airway pressure. The measured value is required to regulate the blower.

Solenoid valves V6.1, V6.2 and V6.3 calibrate the inspiratory pressure sensors and the expiratory pressure sensor. During calibration, the corresponding valve interrupts the connection to the ventilation circuit and switches the
sensor to ambient pressure.

Flow sensor S1 measures the inspiratory gas flow. Its measurement variable
serves as the basis for calculation of the necessary oxygen flow and thus to
operate the oxygen flow control valves V7.1 to V7.8, to control the mandatory
breaths and to monitor the functions of the unit. The sensor includes a temperature measurement function to measure the inspiratory gas temperature.
Fig. 22 Detail view of functional diagram; flow sensor
Flow sensor S2 measures the flow via the expiratory valve to the outlet. The
flow sensor used is the Spirolog sensor from the Evita series (temperaturecompensated hot wire flowmeter with no detection of flow direction). The signal is used for patient monitoring (e.g. minute volume monitoring) among
other applications.

the following conditions:
– after 8 operating hours
– after replacing the O2 sensors
– if sensor 1 and sensor 2 vary by more than 2 Vol.%
– after the air pressure changes by more than 200 hPa e.g. during helicop-
ter transfers
– after a temperature change of more than 10 °C.
During automatic calibration the info line on the monitor shows: O2 calibra-
tion active.
After successful calibration the display shows: O2 calibration OK.
