The UNO Gas Exhaust Unit can be used for the direct exhaust of waste anesthetic and exhaled gas when using face masks for rats or mice. It can also be used for the indirect exhaust of excess anesthetic gas from the circle system with the UNO Micro Ventilator at various volume and pressure settings.
To avoid anesthetic gas spill and maintain optimal functioning of the unit, the gas mixture supply to the face masks should be set to a maximum of:
- Face mask – rat: -350 ml/min*1
- Face mask – mouse: -260ml/min*2
The supply of the anaesthetic gas mixture to the UNO Micro Ventilator (UMV) is set at a lower level, because with the use of the UMV and the correct size intubation tube, there is hardly any waste of anaesthetic gas mixture*3
