Final answer:
Thermal dilution cardiac outputs can be measured using a technique called thermodilution. This involves injecting a cold saline solution into the right atrium of the heart and measuring the temperature change.
Step-by-step explanation:
Thermal dilution cardiac outputs can be measured using a technique called thermodilution. This method involves injecting a cold saline solution into the right atrium of the heart and measuring the temperature change as the solution travels through the heart and into the pulmonary artery. The change in temperature is used to calculate the cardiac output.
