The objective of this study was to develop a software for data interpretation of gasometric applicable in Intensive Care Units that can provide a diagnosis for disorders of acid-base balance. This is an experimental study being selected on a theoretical basis with the Java IDE NetBeans 6.8 through a partnership with professionals trained in Information Systems. The program development was based on creating an algorithm, a sequence of well-defined and unambiguous to be performed mechanically in order to provide a desired diagnosis. We created a software applicable in intensive care units called InterGas, which is a program easy to install, has an interface easy to understand and use, and to process the data quickly and accurately providing as the final diagnosis for the disorder the acid-base balance. The lack of another tool that brings together all the components of InterGas makes it a pioneering software that facilitates decision-making, as it characterizes the occurrence of mixed disturbances using compensation formulas.
