With assist-control,the patient initiates breathing,but the ventilator senses the breath and provides a breath at the preset tidal volume,while backup control delivers a preset number of breaths at a set volume.
Control mode fully regulates ventilation in patients with paralysis or in arrest.It delivers a set tidal volume at a prescribed rate,using predetermined inspiratory and expiratory times.With Assist mode,the patient initiates inspiration and receives a preset tidal volume that augments ventilatory effort.With synchronized intermittent mandatory ventilation (SIMV),the ventilator delivers a set number of breaths and a specified volume.Some patients breathe spontaneously between SIMV breaths at volumes differing from those set on the machine.
