Table 7.

Set and measured inspiratory-to-expiratory time for the ASV in VC-AC mode connected to a passive lung.

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].
