SIMV PCV-VG mode
• Delivers a set rate of pressure controlled breaths with a guaranteed volume
• The ventilator will adjust the inspiratory pressure needed to deliver the set tidal volume breath-by-breath so that
the lowest pressure is used.
• The patient’s compliance is determined from the volume controlled ventilation breath and the inspiratory
pressure level is then established for the next PCV-VG breath.
