Introduction
Over the past decade computers have exponentially increased their role in clinical practice. Medical applications (apps) for mobile devices and laptops are growing in numbers and are nowadays also commonly used in the cardiovascular perfusion field. There are several perfusion directed apps in the market, however, all of them have lack of department directed features. Facing this, Hospital de Santa Marta Cardiothoracic Surgery department – Perfusion team, and the department of Physics – Biomedical engineering of the Universidade Nova de Lisboa, started developing an app for perfusion related parameter calculations
Material & Methods
After an analysis of the most popular perfusion apps in the market, the authors started to develop an app that fully satisfied the needs of the department. The first step was to define the programming language to be used; MATLAB software had been chosen based on an intuitive and easy language. Then came the delineation of the app content, defining parameters to use and calculations to be performed. Results The app is divided in six fundamental parts that interact internally between each other, each one dedicated to a specific topic, allowing the user to insert data, calculating automatically several parameters. After the introduction of patients biometric data, several calculations are automatically done like, body surface area, blood Flow, Heparin /Protamine dose, priming parameters, dilutional hematocrit and modified ultrafiltration volume. A print option is available, if the user wants to attach the app data to the perfusion report at the end of the procedure.
Conclusions
After a few trials, this app reveals safe, intuitive and user friendly, as well as an excellent tool that features department directed perfusion parameters and calculations
