For your safety and that of your

patients

Strictly follow the instructions for use

Any use of the apparatus requires full understanding and strict

observation of these instructions. The apparatus is only to be

used for purposes speciﬁed here.

Maintenance

This apparatus should only be inspected, serviced and

maintained by trained service personnel.

We recommend that a service contract be obtained with

DrägerService and that all repairs also be carried out by them.

Only authentic Dräger spare parts may be used for

maintenance. Observe chapter "Maintenance Intervals".

Accessories

Do not use accessory parts other than those in the order list.

Not for use in areas of explosion hazard

This apparatus is neither approved nor certiﬁed for use in

areas where combustible or explosive gas mixtures are likely

to occur.

Safe connection with other electrical equipment

Electrical connections to equipment which is not listed in

these instructions for use should only be made following

consultation with the respective manufacturer or an expert.

Liability for proper function or damage

The liability for the proper function of the apparatus is

irrevocably transferred to the owner or operator to the extent

that the apparatus is serviced or repaired by personnel not

employed or authorized by DrägerService or if the apparatus

is used in a manner not conforming to its intended use.

Dräger cannot be held responsible for damage caused by

non-compliance with the recommendations given above.

The warranty and liability provisions of the terms of sale

and delivery of Dräger are likewise not modiﬁed by the

recommendations given above.

Precautions

This equipment must only be used under the supervision of

qualiﬁed medical staff, so that if any faults or malfunctions

occur, help is available immediately.

This equipment must not be used with ﬂammable gases

or anaesthetic agents. Danger of ﬁre!

Do not use the apparatus in conjunction with nuclear

spin tomography (MRT, NMR, NMI).

The apparatus may malfunction, causing danger to the

patient.

Do not use the equipment in hyperbaric chambers.

The apparatus may malfunction, causing danger

to the patient.

Avoid pollutants in the ambient air.

Savina uses ambient air for ventilation.

Pollutants would enter the patient’s body.

Interference with operation of the apparatus may be

caused by the use of high-frequency electrical surgical

equipment, deﬁbrillators or short-wave treatment

equipment, thereby putting the patient at risk.

Do not use mobile phones within a distance of 10 metres

from the equipment.

Mobile phones can cause interference with electrical

and electronic medical apparatus, thereby putting patients

at risk!

*

* Dräger medical equipment fulﬁls the interference resistance

requirements according to the product-speciﬁc standards or

EN 60601-1-2 (IEC 601-1-2). However, depending on the design

of the mobile phone and circumstances of use, ﬁeld strengths may

occur in the immediate environment of a mobile phone that exceed

the limits of the above standards and therefore cause interference.

The following points should be noted if ventilating while

travelling:

● Do not place Savina on the bed while travelling.

● Ensure the apparatus cannot fall or be knocked over.

● Protect the apparatus from splashes and rain, to

avoid risk of malfunction. Savina is not splashproof.

During transport conditions, e.g. in an aircraft, hoses may

start to vibrate and thus affect the ﬂow measurement.

When using Savina in combination with other products or

during transport, the operator must secure the equipment

appropriately to comply with the relevant basic

requirements of Directive 93/42/EC.

Appropriate Monitoring

The built-in monitoring facilities of the Savina ensure

appropriate monitoring of ventilation therapy and therefore

detect any undesirable changes in the following ventilation

parameters:

— airway pressure, Paw

— expiratory minute volume, MV

— inspiratory O2 concentration, FiO2

— inspiratory breathing gas temperature, T

— apnoea

— tachypnoea monitoring

Changes in these parameters may be caused by:

— acute changes in the patient’s condition

— incorrect settings and faulty handling

— equipment malfunctions

— failure of power and gas supplies

In the event of a problem with the integrated monitoring:

● separate monitors must be used.

Back-up ventilation with an independent

manual ventilation device

If a fault is detected in the Savina so that its life-support

functions are no longer assured:

● start ventilation using an independent ventilation device

without delay, if necessary with PEEP and/or increased

inspiratory O2 concentration (e.g. with the Dräger

Resutator 2000).

Operation

Run equipment check according to checklist, see page 96.

Starting Up

Switching on

1 Turn the main switch on the back of the apparatus to » «

The Savina now runs through a power-up self-test

procedure.

● Wait for the 12-second test phase to be completed.

At the end of the test phase, the apparatus automatically

starts ventilation with the last ventilation mode set and the

associated ventilation parameters.

During the self-test the start-up page appears, showing the

software version.

After this, the main page appears.

2 Check the settings in the display fields next to the

parameter keys and adjust as necessary.

To adjust ventilation parameters:

Either

2 Change the ventilation parameters after the Savina has

started ventilation

or

3 Press the » Standby« switch to set the Savina on

standby,

4 Confirm = press »Alarm Reset« key.

2 Change the ventilation parameters and

3 press the » Standby« switch to return to ventilation.

Setting Ventilation Modes

Setting the ventilation parameters

1 Press the appropriate ventilation mode key.

The yellow LED in the key will light up.

2 Set the desired value = turn the rotary knob,

confirm value = press the rotary knob

The yellow LED in the key will go out.

If the setting is at the upper or lower limit of the adjustment

range for a parameter, the ﬁgure in the parameter key display

will start ﬂashing, indicating that conﬁrmation is required.

● Press rotary knob in order to confirm extreme values.

● To set value = turn rotary knob,

to confirm = press rotary knob

Parameter settings for the active ventilation mode do not

become operative until conﬁrmed.

If you fail to conﬁrm the new settings within 15 seconds,

the previous settings will remain operative.

Extreme settings

Certain ventilation parameters are limited by Savina to a

threshold value. Extreme values can only be set after

conﬁrmation by pressing the rotary knob.

Conﬁrmation is not necessary when the values are returned to

the normal range.
