Abstract: The present paper proposes the development of a new branch of Irreversible Thermodynamics that can be named Biologica Quantum Thermodynamics with Finite Speed. The development of this sub-discipline is based on establishing the quantified correlation between the speed of the heart Fi and the speed of the lungs Fp in the stationary quantum states of the Cardio-Pulmonary System and on the possibility of representing the interaction processes (with quantum jump) using five diagrams. The aim of the paper is the finding of analytical expressions of the Efficiency and Power of the two components, the heart and the lungs, of the Cardio-Pulmonary System using Thermodynamics with Finite Speed. These analytical expressions are based on the invention and introduction of a new diagram PV/Px for the Cardio-Pulmonary System, similar with that invented and introduced for Stirling Machines, which have two pistons in a continuous interaction with each other. In a similar way, the Cardio-Pulmonary System is made of “two Thermal Machines with a piston”: the Lungs = volumetric air compressor; the Heart = pump for liquid (blood) with valves. Based on this analogy we establish the basis of treating Irreversible Processes with Finite Speed from this Biological System permanently oscillating (as long as the person is alive).
