ESO 2 ICU Ventilator 49 User Manual
Operational Capability
Tidal Volume, Rate, and I:E ratio settings are all limited by
a maximum inspiratory flow of 75 L/min, and a minimum
flow of 2 L/min.
The ventilator is capable of operating at the volumes and rates
below each I:E ratio curve.
Example
1. Select required volume: V
T
= 1.0 L
2. Select rate = 20 bpm
In this example, the point of intersection X on the graph shows
that an I:E ratio can be set from 1 : 0 .3 to 1 : 4, as these
curves are all above the intersection point.
Similarly, a ratio of 1:5 cannot be set, as this is below the
intersection point.
