Accuracy of the Set Tidal Volume During Intraoperative Anesthetic Care: An In Vitro Evaluation

Tables
| Setting | Patient mode | Ventilator mode |
|---|---|---|
| The data are presented as the mean ± SD. Each value was calculated from 250 breaths. The volumes listed as patient mode were measured by the pneumotachometer placed between the 15 mm adaptor of the endotracheal tube and the ventilator circuit. The volumes listed as ventilator mode were measured internally by the anesthesia machine. SD: standard deviation; PIP: peak inflating pressure; Vt: tidal volume. | ||
| Vt 50 mL | 51 ± 0.2 | 50 ± 0.1 |
| Vt 100 mL | 97 ± 0.2 | 100 ± 0.2 |
| Vt 200 mL | 190 ± 0.2 | 200 ± 0.7 |
