WebGas Laws. Four main factors, also known as Fick’s Law, influence the rate at which gases will diffuse across the layers of the respiratory membrane. They are: 1) thickness of the membrane; 2) surface area of the membrane; 3) diffusion coefficient of gases in relation to the membrane; and 4) partial pressure differences of the gases. WebThe Fick principle states that blood flow to an organ can be calculated using a marker substance if the following information is known: ... In reality, this method is rarely used due to the difficulty of collecting and analysing the gas concentrations. However, by using an assumed value for oxygen consumption, cardiac output can be closely ...
