Normal inspiratory to expiratory ratios (I:E) on spontaneously breathing patients are usually around 1:3 to 1:5. Meaning, the ratio of time in expiration is 3 to 5 times longer than the ratio of time in inspiration. Think logically about the time you take when you breathe to inhale and exhale.
The Internal-External (IE) Matrix positions an organization’s various divisions in a nine cell matrix. The IE Matrix is a strategic management tool which is used to analyze the current position of the divisions and suggest the strategies for the future.
From this we can work out how much of that total cycle time is inspiration and how much is expiration- this is the inspiration:expiration ratio or I:E ratio. We can set our inspiratory time via the ventilator in many modes of ventilation.
17 Μαΐ 2021 · An example five-division IE Matrix is given in Figure 6-12. Note that Division 1 has the largest revenues (as indicated by the largest circle) and the largest profits (as indicated by the largest pie slice) in the matrix.

Set Respiratory rate: What you plug into vent. Measured Respiratory rate: How many actual respirations the patient is taking. 60 seconds in a minute ÷ measured respiratory rate of 20 = total cycle time of 3 seconds. I:E Ratio. So for inspiration and expiration you have 3 seconds.
