The regression model could not be developed using simple respiratory parameters. Therefore, we introduced a new variable, defined as flow ratio, which equaled the HFNC flow divided by inspiratory flow. Our equation demonstrated that the actual FiO 2 was mainly determined by the flow ratio in a ...
Assuming the existence of a (quasi) steady-state metabolism throughout the metabolic network, the first fundamental balancing equation can be written as: (1) Here, the metabolic network is expressed as stoichiometric matrix S with the dimension dim S = (m× q), where m is the number of ...
