  • increase cardiac output

The heart has a metric called cardiac output.

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.

    Academic text (2011)
  • The stroke volume increased 16 percent, and the cardiac output increased 18 percent at the 30 degrees g tilt position.

    Academic text (2000)
  • Both groups showed between a 12% and 30% increase in stroke volume and cardiac output.

    Academic text (2000)
  • The decrease in cardiac output is counterbalanced by an immediate increase in heart rate.

    Academic text (2002)
  • Decreased cardiac output is a risk secondary to hypovolemia.

    Academic text (2005)
  • Stroke volume decreased with increasing tilt angles, while cardiac output decreased only at 10 degrees.

    Academic text (2000)
  • Cardiac output during hybrid exercise was significantly higher than during either FES-LCE or ACE performed individually.

    Academic text (1992)
  • At such doses, dopamine has a systemic b-adrenergic effect with increases in cardiac output, heart rate, and blood pressure.

    Academic text (2000)
  • Hypovolemic symptoms may also be present, which may include hypotension, increased heart rate, and altered cardiac output and central venous pressure.

    Academic text (2004)
  • Assessment of cardiac output, arterial and central venous pressure, and pulmonary artery pressure enables calculation of systemic and pulmonary vascular resistance.

Morphology

cardiac + output

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.
