Question

Using fick's equation with O2 consumption rate of 50 mlO2/kg/min in a vertebrate.

VO2 = Q βO2(PaO2-PvO2)

VO2= 50 mlO2/kg/min

how to measure the oxygen consumption in a fish using fick's equation.

Answer 1

Fick's law states that when the blood flows gradually, more oxygen is withdrawn from circulation, and due to that saturations are lowered. The measure of cardiac output is done by taking into consideration the intake of oxygen and dividing it by the difference in arteriovenous oxygen concentration. Carp is a category of freshwater fish, so here we discuss the oxygen consumption and cardiac output of carp. The study of the oxygen consumption of fishes gives an idea about its metabolic activity. As per research, a cardiac output of 18.3 ml/mg per kg. The cardiac output is synonymous to oxygen consumption, thus providing us an idea about the consumption of oxygen. The bloody supply via the gill directly correlates to the oxygen consumption of the fishes. During a condition of anemia of the fish, the cardiac output increases and during the time of a decline in the O2 tension of the water in which the fish resides, there is an increase in the cardiac output.
