Set and expired tidal volumes during inflations that were followed by an interrupted expiration
| Infant | Set VTe (ml/kg) | Mean and (range) of VTe (ml/kg) for inflations followed by an interrupted expiration | ||
|---|---|---|---|---|
| 1st part before interruption | 2nd part after interruption | Delivered VTe overall | ||
| Shows the mean and ranges of the expired volumes during the first part, before the interruption, the part after the interruption, and the total. The last line shows the mean and SD for all infants and the difference between the total expired volume and the set expired tidal volume. | ||||
