Electric power supply unit: the battery powers the system with direct
current if the alternate current supply is not available. On the basis of
the ventilator settings, the battery can provide back-up power for at
least 3 hours in rated and perfect working conditions.
Category of conditions detected during functioning of the system
implying an open safety status. A fan FAILURE means that the fan
cannot be clinically used and must be repaired immediately.
Expiratory pause, a manoeuvre started by the operator which closes
the inspiratory and expiratory valves during the expiratory phase of a
breath.
Parameter set by the operator and monitored. The % setting of FiO
determines the percentage of oxygen in the gas delivered to the
patient. The monitored data of the % of FiO
of oxygen delivered to the patient, measured on the inspiratory line.
Method of recognition of the inspiratory effort of the patient, during
which the ventilator controls the basic flow circulating in the patient
circuit. An inspiratory attempt by the patient is translated into a
decrease of the basic flow, which the ventilator recognizes as a
spontaneous breath and delivers a synchronized breath.
Graphics user interface, the part of the ventilator which comprises the
screen, the keys and the knob. The GUI is equipped with an
independent CPU which monitors the data of the ventilator and the
patient. The screen displays the monitored information, including the
alarms, the monitored parameters, the graphs, the ventilator settings
and the messages.
As defined by the international standards organizations, this is an
alarm which requires immediate intervention to ensure the safety of
the patient. During a high priority alarm, the corresponding red signal
flashes rapidly, a high priority acoustic alarm signal is emitted
(a series of five tones repeated twice, followed by a pause, then
repeated again) and an alarm message is displayed in the upper part
of the screen.

Hertz (unit of measurement of frequency, indicating cycles per
second).
