Question

What precautions need to be taken in order to euthanize mice by carbon dioxide inhalation while ensuring the least amount of stress to the animals?

Answer 1

Be using a flow rate that moves 30% to 70% more volume through the cage or chamber each minute precautions need to be taken.

Inhale- To breathe in is to inhale. In contrast to "exhale," which is to breathe out, it is the reverse. Through our lips and nostrils, we take air into our lungs when we inhale, and breathe out again.

Lungs- The two spongy, pinkish-gray organs in our chest are our lungs. Air enters our lungs during inhalation, and oxygen from that air travels to our blood during breathing. Additionally, a waste gas called carbon dioxide travels from the blood to the lungs where it is expelled.
