Set values | Measured value | |||
Respiration rate (brpm) | Inspiratory time (secondsa) | Inspiratory-to-expiratory ratiob | Inspiratory-to-expiratory ratio | |
20 | 1.5 | 1:1 | 1:0.9 | |
20 | 1 | 1:2 | 1:2.0 | |
20 | 0.75 | 1:3 | 1:2.9 | |
20 | 0.6 | 1:4 | 1:3.9 |
aThe measured uncertainty on the inspiratory-to-expiratory ratio is less than the rounding error.
bThe required range of the inspiratory-to-expiratory ratio is 1:1 to 1:4 [10].
