The Newport E100i is a time-cycled, pressure limited adult/pediatric transport ventilator with A/C, SIMV, and Spontaneous (CPAP) modes. The Pressure Relief can be set to vent excess pressure during inspiration. A toggle switch (see back view below) supplies continuous flow from the blender to a reservoir bag for spontaneous breathing during SIMV and CPAP. Control settings include Inspiratory Time in seconds, Peak Flow in L/second, and Breaths per Minute.
