WARNING
• In the event that Emergency Ventilation is
activated, provide the patient with an alter -
native ventilation mechanism, and find the
cause that generated this event. If it was
activated by the delay in accepting the first
initial calibration screen, restart the unit to
ventilate the patient.
• SAFETY VALVE: located immediately before the outlet to the patient. It opens when
the pressure within the patient circuit reaches a value of 120 ± 5 cmH
2
O. The gas
mixture passes into an internal collector and is discharged to the outside.
• INSPIRATORY RELIEF VALVE (ANTI-SUFFOCATION): this valve allows the pa -
tient to inspire room air, when the unit is energized, or when the ventilator is in
inoperative status.
• OPERATING GAS LEAKAGE: The gas that can seep into the unit is collected in
a common manifold, and directed towards the outside.
• LACK OF COMPRESSED AIR PRESSURE: compressed air is used as a control
gas of the pneumatic circuit. When this is lacking, oxygen can replace it. Further-
more, when the unit detects lack of air, it automatically switches to an O
2
concen-
tration of 100%.
• LACK OF OXYGEN PRESSURE: in this case, the air takes the place of oxygen,
and the breaths are delivered with an O
2
concentration of 21%.
• AUTO-ZEROING: every 10 minutes, or when the operator enables it (by pressing
[Ctrl] + [Ctrl] ) all pressure sensors are zeroed. This restarts the readings, avoi-
ding offset errors of the measured pressures. During the first minutes of ventila -
tion, the ventilator can implement resets with a frequency greater than the one
stated. At each reset, a message is displayed in the Icons and messages bar
indicating that this procedure is being performed.
