SynchroMix

When you want to use several drugs in the same infusion reservoir, it is necessary to calculate the volume to include of each of the drugs. From a determined daily dose, and from the available concentration of each drug, there is a single solution for the volume of each one. By solving this problem, the duration of the deposit is also determined based on its total volume and the actual concentration of each drug after mixing. SynchroMix is a calculator that allows, based on the volume of the reservoir, and the available doses and concentrations of each drug (up to 3), to calculate the volume to use of each one, the actual concentration and the duration of the deposit. The sole purpose of these results is to check the calculations previously carried out to determine the parameters of the mixture, or to simulate different situations for educational purposes. The results previously obtained by a person qualified to do them always prevail and SynchroMix is only one more tool to check the validity of those calculations. In no case should this data be used without having previously performed the calculation by other means and SurgicEn is exempt from any responsability due to misuse of the application, error in the definition of the data or error of calculation due to the internal processes of the application.
