Mode
Ventilation mode; an algorithm which determines the type and
sequence of ventilation: the system offers a series of possible
choices, including assisted, spontaneous or synchronized ventilation.
ms Millisecond (unit of time).
NIST Non-interchangeable screw thread: standard for high pressure gas
inlet connectors.
Patient circuit
All the inspiratory-expiratory conduits, including the tubes, the
humidifier and the filters (when foreseen).
PAW Measured airways pressure
PCV Pressure controlled ventilation: a type of controlled ventilation during
which the ventilator delivers an inspiratory pressure set by the
operator for an inspiratory time also set by the operator.
PEEP Positive end expiratory pressure: the minimum level of pressure
maintained in the patient circuit during ventilation. Parameter set by
the operator and monitored.
Pressure Trigger Method of recognition of the inspiratory effort of the patient, in which
the ventilator controls the pressure in the patient circuit. The
ventilator enables ventilation when the airways pressure decreases
by an amount at least equal to the selected threshold value in a
defined period of time.
PSV Pressure support ventilation: a type of spontaneous ventilation in
which the ventilator delivers pressure set by the operator during the
inspiratory phase.
RAM Random access memory
Resistance (Ri) The drop in pressure caused by a flow passing through a conduit:
measured in cmH
2
O/(litres/sec) or hPa/(litres/sec).(peak pressure -
pause pressure / inspiratory flow).
sec Second (unit of time).
SIMV+PS
Synchronized Intermitted Mandatory Volumetric ventilation with
spontaneous ventilation by pressure support.
SPONT In SPONT mode, the patient activates all ventilations delivered by
ventilator without any controlled respiratory rate set. The patient
makes spontaneous breaths by pressure support.
STANDBY Ventilation system in pause status: no ventilation is enabled when the
ventilator is in this status.
