ATTENTION

Do not reuse disposable accessories!
The necessary reconditioning may lead to the deterioration of mechanical and
biological product properties, posing a significant risk to the patient. In addition,
reusing such accessories dangerously increases the risk of contamination for the
patient.

ATTENTION

The sole responsibility for selecting a suitable patient monitoring system that provides
reliable data about the correct functioning of the medical device and the condition of
the patient lies with the user of the ventilator. Different techniques can be used to
monitor patient safety, from the electronic monitoring of the correct functioning of the
medical device and the condition of the patient to simple direct observation of the
patient. The sole responsibility for selecting a suitable patient monitoring technique
lies with the user.

ATTENTION

All electrical cables and gas connections connected to the medical device must
comply with applicable standards.

NOTE

The applied parts of the EVE (CO2 sensor, SpO2 sensor and ventilator breathing
system (VBS)) are protected against defibrillation.

For the SpO2 and CO2 module, the recovery time is under 5 seconds.

Therapeutic scope

1.4 Intended use

The EVETR is used for invasive and non-invasive ventilation in emergency
and transport settings. The EVETR is suitable for long-term ventilation.
The ventilator is available in different feature levels and can be used by
first responders as well as for ground, water, or air transport. The EVETR
is suitable for the ventilation of children and adults weighing up to
200 kg. It is also possible to ventilate preterm infants and newborns.

The EVETR supports the following types of ventilation:

DANGER

Identifies potentially dangerous situations that result in death or life-threatening injury
if not avoided.

WARNING

Identifies potentially dangerous situations that may result in death or serious injury if
not avoided.

CAUTION

Identifies potentially dangerous situations that may result in minor or moderate injury
if not avoided.

ATTENTION

Identifies potentially dangerous situations that may result in minor or moderate injury
to the patient or user or damage to the medical device if not avoided.

NOTE

Identifies additional information that is useful for device operation and intended to
avoid problems during use.

2 Safety instructions

The following safety instructions are repeated at relevant points in the
operating manual and must be observed at all times.

2 Safety instructions

34

GA-070T-0518V2.7-HAO-EN

 Fritz Stephan GmbH

2.1 Danger

DANGER

The device must only be operated by authorized and properly trained professional
staff. The device must be operated according to the instructions in this operating
manual.

DANGER

The device is not certified for use in potentially explosive environments!

DANGER

The device must not be used in areas with contaminated air.

DANGER

Risk of explosion!

Do not use any combustible or anesthetic gases.

DANGER

Use of the device in the vicinity of magnetic resonance imaging systems may degrade
its functionality, which can potentially put the patient and operator at risk.

GA-070T-0518V2.7-HAO-EN

35

2.2 Warning

WARNING

Lack of an alternative ventilation method, such as a self-priming operator-powered
resuscitator (according to ISO 10651-4), may result in patient death if the ventilator
fails. Always have a separate manual breathing bag handy.

WARNING

Only authorized customer service staff of FRITZ STEPHAN GMBH are permitted to
alter, modify, repair, or open the device, or to replace the internal battery. Only use
spare parts from FRITZ STEPHAN GMBH for maintenance.

WARNING

Do not operate the device outside the specified ambient conditions (see chapter 1.9).
Otherwise, device functionality may be impaired.

WARNING

The ventilator suctions ambient air to create compressed air. It must therefore never
be covered during operation or placed so that its operation or performance is impaired.
Failure to comply may result in device failure or damage and therefore pose a risk to
the patient.

WARNING

If the ventilator is to be operated with additional O2, the O2 supply pressure must be

2.8 – 6 bar (see chapter 1.9).

WARNING

The displayed O2 concentration is not a measurement. Instead, the gas concentration is
calculated from the flow rates.

2 Safety instructions

36

GA-070T-0518V2.7-HAO-EN

 Fritz Stephan GmbH

WARNING

Connecting a different type of gas instead of O2 (such as compressed air) will falsify
the displayed O2 concentration.

WARNING

Using the ventilator in a contaminated environment may be dangerous.

WARNING

Excessive ventilation modes can increase the temperature of the patient's breathing air
up to 43° C. Normal ambient temperatures counterbalance this effect.

WARNING

Only use patient tubing and accessories listed in chapters 1.2 (Product combination)
and 12 (List of accessories). Using other patient tubing or accessories not intended for
use with the ventilator may impair device performance and safety.

WARNING

When operating normally or in the event of the first fault, the tube system can be
contaminated with body fluids or exhaled gases by the ventilator up to the expiration
valve.

WARNING

Burns may be caused by antistatic or electro-conductive patient tubing when using
electrical high-frequency surgical instruments at the same time. Therefore, do not use
antistatic or electro-conductive patient tubing or lines.

WARNING

Never pull on patient tubing or electrical cables. This may cause the device to tip over
or drop.

2 Safety instructions

 Fritz Stephan GmbH

GA-070T-0518V2.7-HAO-EN

37

WARNING

Short-wave therapy devices, RF diathermy devices, defibrillators, and similar
equipment in close proximity of the device may impair device functionality. In such
cases, the patient and device must be monitored continuously.

WARNING

Never use the ventilator in a hyperbaric chamber.

WARNING

Never operate the ventilator with nitric oxide, helium, or mixtures containing helium.

WARNING

During non-invasive ventilation, a CO2 monitor for measuring the expiratory CO2
level must be used. The EVETR can be optionally equipped with an internal CO2
measuring unit. Otherwise, an external measuring unit must be used.

WARNING

During non-invasive ventilation, the exhaled volume may differ from the measured
exhaled volume if the mask is not fully sealed.

WARNING

FRITZ STEPHAN GMBH recommends using the pressure-controlled ventilation method
PC-CMV in the case of suction. To prevent the occurrence of negative pressures, the
PEEP must be set to a minimum of 4 mbar.

WARNING

Treat the individual parts carefully to avoid mechanical damage.
Only use correctly prepared parts to operate the device.

2 Safety instructions

38

GA-070T-0518V2.7-HAO-EN

 Fritz Stephan GmbH

WARNING

IEC 60601-1 and IEC 62353 must be observed specifically for medical devices with
an electrical connection. According to these directives, these devices must only be
repaired by the manufacturer or an entity explicitly authorized by the manufacturer for
this purpose.

WARNING

Check that no condensation accumulates near the Y piece of the inspiration tube
which could leak into the flow sensor.

WARNING

Make sure that there are no water droplets in the pressure measurement lines.

WARNING

After using the special alarm suppression state, make sure that the alarm is reactivated
before leaving the patient.

WARNING

FRITZ STEPHAN GMBH recommends that the ventilator is not operated with a low
battery (capacity <10%) because the device will switch off immediately in the event
of a power failure.

WARNING

Incorrectly selected trigger thresholds and large leaks may cause auto-triggering! In
this case, the trigger threshold has to be manually adjusted.

WARNING

When adding system components or sub-assemblies to the ventilation system of the
ventilator, the pressure gradient across the ventilation system, measured at the patient
connection port, may negatively affect the performance data of the ventilator.

WARNING

The use of accessories, transducers, and cables other than those specified, with the
exception of transducers and cables sold by the manufacturer of the medical electrical
equipment or system as replacement parts for internal components, may result in
increased emission or decreased immunity of the medical electrical equipment or
system.

WARNING

Medical electrical equipment or systems should not be used adjacent to or stacked
with other equipment. If adjacent or stacked use is necessary, the medical electrical
equipment or system should be monitored to verify its intended operation in the
configuration in which it is used.

WARNING

No modifications to the EVETR are permitted without the manufacturer's
authorization!
