I:E Ratio Formula
The following formula is used to calculate the I:E Ratio.
IE = IT / ET
- Where IE is the I:E Ratio
- IT is the total inspiratory time
- ET is the total expiratory time
To calculate an I E ratio, divide the total inspiratory time by the total expiratory time.
How to Calculate I:E Ratio?
The following example problems outline how to calculate I:E Ratio.
Example Problem #1:
- First, determine the total inspiratory time.
- The total inspiratory time is given as: 2.
- Next, determine the total expiratory time.
- The total expiratory time is provided as: 4.
- Finally, calculate the I:E Ratio using the equation above:
IE = IT / ET
The values given above are inserted into the equation below and the solution is calculated:
IE = 2 / 4 = .5
Example Problem #2:
For this problem, the variables required are provided below:
total inspiratory time = 5
total expiratory time = 6
Test your knowledge using the equation and check your answer with the calculator above.
IE = IT / ET = ?
