Cardiac output

In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols Q {\displaystyle Q} , Q ˙ {\displaystyle {\dot {Q}}} , or Q ˙ c {\displaystyle {\dot {Q}}_{c}} , is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time…
