A message that appears together with alarm signalling; it consists of a
basic message that identifies the alarm type.
Minute (unit of time).
Millilitre (unit of volume).
Ventilation mode, algorithm that determines the ventilation type and
sequence: the system offers a series of possible choices, including the
possibility to choose between assisted, controlled, spontaneous or
synchronised ventilation.
Millisescond (unit of time).
Non-interchangeable screw thread: a standard for high pressure gas
input connectors.
Expiratory pause, a manoeuvre started by the operator that closes the
inspiration and expiration valves during the expiration phase of a
respiratory act.
Inspiratory pause, a manoeuvre started by the operator that closes the
inspiration and expiration valves during the inspiration phase of
controlled ventilation. The manoeuvre can be used to determine the
static compliance (C) and the resistance (R).
Pressure of the measured airways.
Positive pressure at end of expiration, the minimum pressure level
maintained in the patient circuit during ventilation. A parameter set by
the operator and monitored.
Pressure support ventilation: a type of spontaneous ventilation where
the ventilator supplies pressure set by the operator during the
inspiratory phase.
Ventilation system in stand-by: no ventilation is active when the
ventilator is in this mode.
RAM Memory with casual access.
The ratio between the inspiration time and the expiration time.
The pressure drop caused by the passage of a flow through a tube:
measured in cmH2O/(litres/sec) or hPa/(litres/sec). (peak pressure –
pause pressure / inspired flow).
Second (unit of time).
Volumetric synchronised intermittent mandatory ventilation with
pressure support spontaneous phase.
In SPONT mode, the patient activates all the ventilation supplied by
the ventilator with no set controlled respiratory frequency. The patient
undertakes pressurised supported spontaneous breathing.
