module, to measure the use of anesthetics or recently used
anesthetic animals, the vent on the module must be connected to the exhaust gas treatment system,
anesthesia machine or ventilator, to avoid medical personnel inhalation anesthetic.
6.9 C.O. (Optional)
6.9.1 General Description
Warning

C.O. monitoring is restricted to animals > 20 kg only.
The cardiac output (C.O.) function invasively measures cardiac output and other hemodynamic parameters by
using the thermodilution method. A cold solution of known volume and temperature is injected into the right
atrium through the proximal port of a pulmonary artery (PA) catheter. The cold injectable solution mixes with the
blood in the right ventricle and the change in blood temperature is measured with a thermistor at the distal end of
the catheter in the pulmonary artery. The C.O. Cable Socket is shown as follows:
6.9.2 Influencing Factors of Measurement

temperature of injectable solution

volume of injectable solution

animal‘s baseline blood temperature

animal‘s inspiratory/expiratory cycle

the extent of proximity of the distal end of catheter and the lung

the PA catheter itself

the animal heart rate and hemodynamic status

any other rapid IV solutions which are injected while the C.O. measurement is being performed
