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.
Hectopascal (unit of pressure, approximately equal to 1 cmH
Hertz (unit of measurement of frequency, indicating cycles per second).
The ratio between inspiratory time and expiratory time
International Electro-technical Commission: international organization for
the definition of standards.
Inspiratory pause, a manoeuvre started by the operator which closes the
inspiratory and expiratory valves during the inspiratory phase of a breath.
This manoeuvre can be used to determine the static compliance (C) and
the resistance (R).

Kilogramme (unit of weight).
Litre (unit of volume).
Litres per minute (unit of flow).
Parameter-based curve with respect to time
As defined by the international standards organizations, this is an alarm
that indicates a change in the patient-ventilator system. During a low
priority alarm, the corresponding yellow signal lights up and an alarm
message is displayed in the upper part of the screen.
Meter (unit of length).
All the operations necessary to maintain the equipment in working order or
to carry out cleaning, maintenance, repairs, modifications, revisions and
performance checks.
If the MANUAL key is pressed in PSV mode, the system delivers pressure
controlled ventilation to the patient.
