How much oxygen a mouse breathes in per minute per gram of body weight versus how much humans breathe in?

A mouse breathes in approximately 0.5 to 1.5 milliliters of oxygen per minute per gram of body weight, which is significantly higher than humans. In contrast, an average human breathes in about 0.3 to 0.4 milliliters of oxygen per minute per gram of body weight. This difference is largely due to the higher metabolic rate and greater surface area-to-volume ratio in smaller animals like mice.
