CARDIAC OUTPUTS Meaning and
Definition
-
Cardiac output refers to the volume of blood that is pumped by the heart per unit of time, typically measured in liters per minute. It is a key physiological parameter that reflects the overall function and efficiency of the cardiovascular system. Cardiac output is essential for ensuring an adequate supply of oxygenated blood to meet the metabolic demands of the body's tissues and organs.
Cardiac output is calculated by multiplying the stroke volume, which is the amount of blood ejected by the left ventricle with each heartbeat, by the heart rate, which is the number of times the heart contracts per minute. Therefore, it can be expressed as the product of stroke volume and heart rate.
This measurement is crucial in assessing cardiovascular health and diagnosing various cardiac and circulatory disorders. It provides valuable information regarding the heart's ability to pump blood effectively and efficiently. Factors that influence cardiac output include heart rate, stroke volume, and systemic vascular resistance. In situations of increased demand, such as during exercise or stress, the body can compensate by increasing cardiac output to meet the increased oxygen requirements.
Abnormal cardiac output levels can indicate various conditions, including heart failure, cardiac arrhythmias, fluid imbalance, or other problems affecting the heart or blood vessels. Monitoring and evaluating cardiac output is an important tool utilized by medical professionals in patient care, as it assists in treatment planning and helps guide interventions to optimize cardiovascular function.

Etymology of CARDIAC OUTPUTS
The term "cardiac outputs" consists of two words: "cardiac" and "outputs".
1. Cardiac: The word "cardiac" derives from the Greek word "kardiakos" (pertaining to the heart), which is related to "kardia" (heart). The Greek term eventually evolved and was adopted into Latin as "cardiacus". Over time, it entered the English language as "cardiac" to refer specifically to the heart.
2. Outputs: The word "outputs" is a noun form of the verb "output". It emerged in the late 19th century and combines the prefix "out-" (indicating movement away) and "put" (from Middle English "puten", meaning "to place").
