Definition
Adjustable pressure level at which patient pressure is
limited. No alarm occurs. Tidal volume delivery may
decrease when Limit Pressure is reached.
Any breath that is controlled and terminated by the
ventilator in order to achieve a preset tidal volume
(volume controlled breath) or a target pressure for a
preset time (pressure control breath).
An operator-initiated ventilator breath that is delivered
when the Manual Breath button on the keypad is
pressed. The ventilator delivers the type of mandatory
breath currently set. If a mandatory breath is not set,
the ventilator uses the patient weight and the volume
control setting to deliver a manual breath.
A predetermined time limit for inspiratory time for all
breath types (normally 3 seconds).
The average airway pressure throughout the breath
cycle.
A period of time starting at the beginning of the
exhalation phase, during which any type of breath
cannot be initiated.
Nebulizer is a pneumatic device that uses compressed
gas to deliver aerosolized medication that can be
inhaled by patients. During nebulization, the flow is
synchronized with the inspiratory phase of each breath.
The tubing, valve and flow sensor that provides the
ventilatory interface between patient and ventilator.
Any ventilator-delivered breath that is initiated and
terminated by the patient. Initiation is by flow or
pressure trigger and termination is by decrease in flow
or increase in pressure. Available in SIMV, PCV, Adaptive
Bi-Level and CPAP modes.
Any inspiratory effort initiated by the patient.
Airway pressure (cmH O).
2
A type of ventilation in which the ventilator breaths are
controlled by pressure, terminated by time, and limited
by volume.
