Table 2. The estimated concentrations in percent [%] of the chamber volume (CV) for all analyzed narcotic gases and both mouse strains at the onset of LORR and LOPR.
| NMRI | Gas concentration [%] CV | |
|---|---|---|
| LORR | LOPR1) | |
| CO2 20 | 31.1 | 58.1 |
| CO2 60 | 44.3 | 61.0 |
| CO2 100 | 57.3 | 66.2 |
| Iso 2% | 1.8 | 1.9 |
| Iso 5% | 3.1 | 3.5 |
| Sevo 4.8% | 4.2 | 4.6 |
| Sevo 8% | 5.6 | 6.5 |
| C57Bl/6J | Gas concentration [%] CV | |
| LORR | LOPR1) | |
| CO2 20 | 30.3 | 48.0 |
| CO2 60 | 45.1 | 55.1 |
| CO2 100 | 56.6 | 65.3 |
| Iso 2% | 1.5 | 1.9 |
| Iso 5% | 2.7 | 3.4 |
| Sevo 4.8% | 3.7 | 4.5 |
| Sevo 8% | 5.0 | 6.0 |
1) Please note that for LOPR this is a rough calculation due to anesthetic gas dilution with ambient air.
