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.
Never use the ventilator in a hyperbaric chamber.
Never operate the ventilator with nitric oxide, helium, or mixtures containing helium.
During non-invasive ventilation, a CO
2
monitor for measuring the expiratory CO
2
level must be used. The EVE
TR
can be optionally equipped with an internal CO
2
measuring unit. Otherwise, an external measuring unit must be used.
During non-invasive ventilation, the exhaled volume may differ from the measured
exhaled volume if the mask is not fully sealed.
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.
Treat the individual parts carefully to avoid mechanical damage.
Only use correctly prepared parts to operate the device.
