cardiac output
- noun
- /ˈkɑrdɪæk ˈaʊtpʊt/
- Specialized
- Doctors monitor the cardiac output to assess the efficiency of the heart's pumping ability.
- cardiac output and stroke
- volume and cardiac output
- increase cardiac output
The heart has a metric called cardiac output.
- The heart has a metric called cardiac output.
- The other drives muscle contract cardiac output to match venous return.
Examples
-
In heart failure, the blood pressure may be low because of reduced cardiac output. However, hypertensive disease is a major cause of heart failure, and the blood pressure may be high if that is the underlying cause.

Morphology
The compound directly combines 'cardiac' (heart-related) and 'output' (amount produced), so its basic meaning — the amount produced by the heart — is transparently derivable from the constituents. While the precise medical detail (ventricular flow per minute) is technical, a B1 learner who knows both words will grasp that it refers to the heart's output.
Etymology
Cardiac output paints the heart as a simple pump: cardiac means 'of the heart' and output is what the pump sends out. So it refers to 'the amount of blood the heart pumps out', usually measured in one minute.
