A tumor whose cells, unlike benign tumor cells, continue to divide uncontrollably, invade normal tissue, and can spread (metastasize) to other parts of the body through the bloodstream and lymphatic system; divided into three broad categories: carcinoma, sarcoma and lymphoma.

Viral infection affecting puppies characterized by general systemic signs possibly leading to cerebellar disease.
Purpose: Instrument used to measure the carbon dioxide (CO2) concentration in exhaled breath and rate of breathing. It is a real time objective assessment of the effectiveness of breathing by directly reflecting the elimination of CO2 by the lungs to an anesthesia device. Indirectly, it reflects the production of CO2 by tissues and the circulatory transport of CO2 to the lungs.
How Works: Measures the absorption of infrared light, which is absorbed particularly well by gases of molecules that contain at least two dissimlar atoms, such as carbon dioxide. The amount of infrared radiation absorbed is proportional to the number of CO2 molecules present in a chamber. Carbon dioxide concentration is measured continuously throughout the respiratory cycle to give a graph of expiratory CO2 plotted against time. When expired CO2 is related to expired volume rather than time, the area beneath the curve represents the volume of CO2 in the breath, and thus over the course of a minute, this method can yield the CO2 minute elimination, an important measure of metabolism. If breathing stops, the CO2 monitor will immediately flat line, whereas the pulse oximeter will appear normal for several minutes.
