What are the proper ranges for CO2 on capnography and blood gas analysis?
|
Capnography ETCO2: 30-40 mmHg
Blood gas analysis PaCO2: 40-45 mmHg |
|
How much time should you take to wean the animal off the ventilator before it can breath on its own?
|
Usually 5-10 minutes
Decrease minute volume by 50% by decreasing tidal volume or frequency (preferred) |
