1General information
FRITZ STEPHAN GMBH disclaims any warranty with respect to the
operation of unauthorized device combinations with products not
approved by the manufacturer or without certified compatibility.
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 (CO2sensor, SpO2sensor and ventilator breathing
system (VBS)) are protected against defibrillation.
For the SpO2and CO2module, the recovery time is under 5 seconds.

1.5 Contraindications
The safety instructions provided in chapter 2 must be observed. No
additional contraindications exist.
It is the sole responsibility of the user to select the most appropriate type
of ventilation based on the patient's medical condition. The continuous
monitoring of the patient's condition must be assured at all times.
Non-invasive ventilation is contraindicated in the following cases:
No spontaneous breathing
Fixed or functional airway obstruction
Gastrointestinal bleeding or ileus
1.6 Disposal
The device packaging largely consists of recyclable or reusable materials.
