Thermodilution is a technique used to measure cardiac output by injecting a cold solution into the bloodstream and observing the temperature change downstream. This method relies on the principle that the degree of temperature change is inversely proportional to the blood flow rate, allowing for accurate cardiac output calculations.

Thermodilution

Cardiac output is the volume of blood the heart pumps per minute and is a critical indicator of cardiovascular health. It is determined by the heart rate and stroke volume, reflecting the heart's efficiency in delivering oxygen and nutrients to tissues.

The bloodstream is a critical component of the circulatory system, responsible for transporting nutrients, oxygen, hormones, and waste products throughout the body. It plays a vital role in maintaining homeostasis and supporting the immune system by circulating white blood cells and other immune factors to sites of infection or injury.

Temperature change refers to the variation in temperature over time, which can be influenced by natural processes and human activities. Understanding temperature change is crucial for assessing climate patterns, predicting weather events, and addressing global warming challenges.

Blood flow rate refers to the volume of blood passing through a vessel, organ, or the entire circulatory system per unit time, typically measured in liters per minute. It is crucial for maintaining tissue perfusion and is influenced by factors such as blood pressure, vessel diameter, and blood viscosity.
