in statistics, the most frequently occurring value or item in a distribution.
1. pacing mode.
2. the manner of interaction between a ventilator and the person being ventilated, usually defined in terms of what the stimulus is that starts the ventilation.
assist mode a mode of positive pressure ventilation in which the patient initiates and terminates all or most breaths and the ventilator gives some amount of support. See also control mode and assist-control mode.
assist-control mode a mode of positive pressure ventilation in which the ventilator is in assist mode unless the patient's respiration rate falls below a certain amount, in which case the ventilator switches to a control mode. When the strength or rate of respiration increases again, the ventilator goes back into assist mode.
assisted mode assist mode.
asynchronous mode a pacing mode in which there is regular stimulation without regard to sensed cardiac signals.
control mode (controlled mode) a mode of positive pressure ventilation in which the ventilator controls the initiation and volume of breaths. See also assist mode and assist-control mode.
inhibited mode a pacing mode in which a sensed event prevents or stops a pacing stimulus and starts a timing cycle.
pacing mode in cardiac pacing terminology, the manner of stimulation of a cardiac chamber by an artificial pacemaker, referring to whether or not sensed cardiac signals (events) are used to inhibit or trigger stimulation. Types include asynchronous, inhibited, and triggered modes.
pressure control mode a mode of positive pressure ventilation in which each breath is augmented by air at a fixed rate and amount of pressure, with tidal volume not being fixed. See also under ventilation.
pressure support mode a mode of positive pressure ventilation similar to the assist mode; the patient breathes spontaneously and breathing is augmented by air at a preset amount of pressure. See also under ventilation.
triggered mode a pacing mode in which the stimulus is emitted in response to a sensed event.
