Lung Inflation Bulb
This device provides a very Safe and Reliable method for verification of tube placement in mice and small rodents. Other methods of tube placement verification require observation of mirror fogging or pronounced abdominal breathing. Being able to visualize mirror fogging is not reliable because the exhaled air of these animals does not consistently result in the mirror fogging that is apparent in larger animals. Verification by pronounced abdominal breathing requires the opening of the trachea tube to be sealed. The animal should exhibit pronounced abdominal breathing with no visible distention of the chest if the tube is placed properly. These methods deprive the animal of oxygen for a period of time causing distress, are highly unreliable, and they consume precious time when the animal could be on the anesthesia machine.
