Table 2.
Response (%) of nine patients to mechanical ventilation with heliox or conventional gas as determined by EIT studies
| Patient | Difference T = 30 to T = 0 (after heliox) |
Difference T = 60 to T = 30 (after nitrox) |
Difference T = 90 t0 T = 60 (after heliox) |
| 5 | 0.5 | 12.9 | -6.4 |
| 6 | 5.0 | 13.8 | -7.7 |
| 7 | 5.1 | 4.5 | -3.8 |
| 8 | -39.0 | 12.4 | -62.2 |
| 9 | -19.6 | 20.3 | 2.3 |
| 10 | -4.6 | 7.7 | -21.9 |
| 11 | 0.0 | -13.7 | -7.5 |
| 12 | 0.3 | 4.9 | 0.0 |
| 13 | 42.1 | -6.9 | -3.8 |
Negative values indicate a decrease in relative change in end-expiratory lung volume (relative ΔEELV).
EIT = electrical impedance tomography.
