A system for monitoring animal body functions by analyzing the condition of the gas being breathed. A breathing tube, usually constituting a portion of anesthesia apparatus, contains sensing means in the form of a thermobead whose electric characteristics vary in accordance with temperature variations as heat is exchanged between the thermobead and the respiratory gas. Electronic analysis of the thermobead characteristics permits animal body functions such as breathing rate, breathing volume, animal body temperature and the like to be determined. Digital displays, recorders and alarms may be activated by the thermobead output.

The method of sensing the breathing characteristics of animals comprising the steps of: (a) passing the animal\s breath through a tube, (b) sensing the velocity of the gas the animal is breathing through the tube during a breathing cycle with a heated diode thermobead, (c) producing a continuous electrical first signal from said thermobead having a value determined by the velocity of the gas being breathed, and (d) producing a continuous second signal from said first signal to permit evaluation of the animal\s breathing functions including duration and volume of each breath, said second signal including an audio signal varying in volume, frequency and duration proportional to the velocity and duration of the gas being breathed during each breath simulating a breathing sound. Apparatus for sensing the characteristics of the breath of animals comprising, in combination, a tube having a passage conducting the gas being breathed by an animal, a heated diode thermobead within said tube passage sensing the velocity and duration of the gas being breathed during the breathing cycle by sensing the exchange of heat between said thermobead and the gas being breathed and producing an electrical output signal proportional to such velocity and duration, and electrical indicator means receiving said output signal and producing a continuous audible indication of the condition of the animal\s breathing functions during the duration of each breath by producing a simulated breathing sound.
