I:E Ratio
The ventilator is capable of operating at the volumes and rates below each I:E ratio curve.
Example
1.
Select required volume (Vt) (e.g. 0.8 L)
2. Select rate (e.g. 10 bpm).
3. Select I:E ratio of 1:2.
The point X on the graph lies beneath the 1:2 ratio curve, and is therefore within the
ventilator’s capability
